Toxic Braiding Hair Is Still Trending. Here Is What Your Scalp Actually Needs.

What the 2025 Consumer Reports tests found in braiding hair, how an ACV rinse fits in, and how to care for your scalp before, during and after your next install.

.8-10 minute read.Reviewed by the NK&Co Editorial Team

A lot of us moved to braids, twists and locs to get away from relaxers and harsh chemicals. So when Consumer Reports announced in February 2025 that it found carcinogens in every synthetic braiding hair product it tested, our community felt it all at once: anger, fear and exhaustion. A year later, the conversation is still going. It has gotten more detailed, more scientific and more important.

This guide covers what the research says, what it does not say, and how to care for your hair and scalp before, during and after your next install. We will also get into apple cider vinegar (ACV) rinses, why one Houston-area salon now includes them in the service, and where a well-formulated scalp oil fits in a healthier protective style routine.

What the Research Found in Braiding Hair

The 2025 Consumer Reports test

In early 2025, Consumer Reports (CR) scientists tested 10 popular synthetic braiding and crochet hair products for heavy metals and 65 volatile organic compounds (VOCs). According to CR's published results:

  • Carcinogens (known, probable or possible) were detected in 100 percent of samples.
  • Three products, all pre-stretched braiding hair, contained benzene, a known carcinogen linked to acute myeloid leukemia.
  • Every sample contained methylene chloride, a probable carcinogen.
  • Lead was detected in 9 of 10 products, and CR's risk analysis found all nine could expose a regular user to a level of lead that could be concerning over time.
  • VOCs were released when the hair was heated to boiling (212°F), similar to the hot-water dip many stylists use to seal ends.
  • There are no federal limits for lead in synthetic braiding hair, so CR measured against California's Maximum Allowable Dose Level, which it considers the most protective benchmark in the U.S.

The 2026 follow-up: human hair and "clean" brands were not off the hook

Readers asked CR to test human hair and brands marketed as safer. In CR's February 2026 follow-up, scientists tested 30 more products, including human hair, plant-based fibers and synthetics with safety claims:

  • Lead was detected in 29 of 30 products. The nine human hair products had the highest lead levels by far.
  • 100 percent of products contained VOCs, including acetone, methylene chloride and benzene at low levels.
  • Only one product had no detectable lead, arsenic or cadmium, which CR said shows braiding hair can be made without detectable heavy metals.
  • Some brands with "lead-free" or "non-toxic" claims still tested positive for contaminants, sometimes at lower levels than others.

A peer-reviewed study widened the lens

In February 2026, researchers at Silent Spring Institute published what they describe as the most comprehensive public testing of hair extensions to date, in the journal Environment & Health. Across 43 products they identified 169 chemicals. According to Silent Spring's summary, 48 appeared on major hazard lists, including 12 listed under California's Proposition 65, and nearly 10 percent of samples contained toxic organotin compounds. Flame retardants turned up in both synthetic and bio-based samples.

Keeping it in perspective

Experts have pointed out that CR's work was not peer-reviewed the way a journal study is (AP News), and CR's exposure model focused on hand-to-mouth transfer, not absorption through the scalp. Cosmetic chemist Michelle Wong of Lab Muffin Beauty Science also broke down how small some of the measured amounts were. None of the experts CR spoke with told people to stop wearing braids. Their advice is to install and wear them with more care, and to remember that exposures add up across every product we use.

Lawsuits and legislation

The findings have moved well past social media. A law firm opened a class action investigation into the brands CR tested, and a class action was filed in federal court in California in late 2025 (Pitre v. Scientific Hair Research). CR petitioned the FDA to assert jurisdiction over synthetic braiding hair and require full ingredient disclosure. In New York, Assembly Bill A7001 would require manufacturers to disclose all ingredients and label products containing carcinogens or reproductive toxicants, and CR is backing the state's Beauty Justice Act. Federally, H.R. 4436 proposes national resources on beauty justice and salon worker safety.

Why Your Scalp Itches Under Braids

Itching is the most common complaint with synthetic hair. Beyond trace contaminants, many synthetic fibers are finished with an alkaline coating that keeps strands from clumping and adds shine. Healthy scalp skin sits at a slightly acidic pH of about 5.5 (Medical News Today), so an alkaline residue rubbing against it all day can leave you flaky, irritated and scratching. Add product buildup, sweat, tension and weeks between washes, and you get the classic braid itch.

Before, During and After: A Smarter Braid Care Routine

Before your install

Choose your hair intentionally. Look for brands that publish third-party test results for heavy metals and VOCs. Be cautious of vague labels like "chemical-free" or "toxic-free" with no data behind them.

Pre-wash or soak your braiding hair. A rinse can lift the alkaline coating and surface residue. Washing will not remove every chemical, such as flame retardants or dyes (Essence), but it can reduce what sits against your scalp.

Start with a clean, moisturized scalp. Cleanse, condition and let your hair dry fully. Do not braid over existing buildup.

Give your hair a break. CR's experts recommend extending the time between installs instead of going from take-down to reinstall within 24 hours.

During your install

Skip the boiling water and burned ends when possible. Heat releases VOCs. If your stylist has to use hot water, ask for good ventilation.

Say something about tension. Braids that are too tight can cause microtears that weaken the skin barrier.

Stylists, protect yourselves. Gloves, clean hands before eating and never holding hair in your mouth all reduce exposure for the people doing this work every day.

While you wear them

Keep your scalp clean. A diluted cleanse or rinse every one to two weeks helps control sweat and buildup.

Use a light oil on the scalp, not a heavy grease. Apply it directly to the parts, then massage gently.

Sleep in a satin bonnet or on a satin pillowcase to reduce friction and frizz.

After take-down

Detangle slowly, cleanse well, deep condition and give your scalp at least a short rest before your next install.

Signs your scalp needs attention

Mild itch in the first day or two can be normal. Pay attention if you notice:

  • Red bumps, sores or a rash along your scalp, hairline or neck
  • Burning, swelling or oozing
  • Itching that gets worse instead of better
  • Hair breakage or thinning at the edges

If you see these signs, take the style down and talk to a dermatologist. You can also report reactions to the FDA through MedWatch and to the Consumer Product Safety Commission at SaferProducts.gov, which CR recommends.

ACV Rinses for Braiding Hair and Scalp

Why apple cider vinegar?

ACV contains acetic acid, which gives it a low pH. On synthetic hair, that acidity helps neutralize and lift the alkaline coating. Many people see a milky white film form in the water during a soak, which is the coating coming off (Makeup.com). On the scalp, a diluted rinse can help break down product residue. A dermatology review in the International Journal of Dermatology notes that vinegar has antimicrobial and antioxidant properties and some evidence for itch relief, and it also warns that misuse can damage skin.

How to do an ACV braiding hair soak

  1. Keep the hair in its bundle and secure it with a rubber band so it does not tangle.
  2. Fill a basin with warm water and mix about 1 part ACV to 3 parts water, enough to fully cover the hair.
  3. Submerge the hair for 15 to 30 minutes. Look for the white film on the water.
  4. Rinse well, then wash with a gentle sulfate-free shampoo until the vinegar smell is gone.
  5. Air dry completely before braiding, ideally the day before your appointment.

How to do an ACV scalp rinse while wearing braids

Dilute much more for skin than for hair. Nebraska Medicine dermatology suggests starting with about half a tablespoon of ACV per 8 ounces of water (Nebraska Medicine). Apply it to your parts with a spray or applicator bottle, massage gently, rinse with water and let your braids dry fully.

Cautions

Never use ACV undiluted on your scalp or skin.

Skip it if your scalp is broken, scratched or inflamed, or if you have eczema or psoriasis and no dermatologist's guidance. In a small study, most people with atopic dermatitis had mild to moderate irritation from a diluted ACV soak (Medical News Today).

Keep it away from your eyes.

Rinse your hair thoroughly. In CR's 2026 testing, one ACV pre-washed product had very high acetone levels, and the brand said vinegar contact was a plausible contributor. Washing and fully drying after a soak matters.

An ACV rinse helps with residue and comfort. It does not remove every chemical or replace choosing better hair.

Arinke Hair & Loc Lounge Is Changing the Game

At Arinke Hair & Loc Lounge, 17627 Beechnut St, Richmond, TX 77407, ACV braiding hair washes are part of the experience. Instead of sending clients home to soak hair the night before, Arinke offers ACV washes for braiding hair so the alkaline coating and surface residue are addressed before your style goes in. For clients in Richmond, Sugar Land, Katy and the greater Houston area, that means fewer itchy first weeks and a stylist who takes scalp health seriously from the start.

Feeding Your Scalp Under Protective Styles

A protective style is only as healthy as the scalp underneath it. Under braids and locs, your scalp is covered, washed less often and exposed to sweat, oil and product. That is the environment where buildup and unwanted bacteria can thrive.

The Nk&Co Hair Growth Collection, led by our hair growth oil, "Ekene" Hair Oil, is plant-based and vegan, formulated for melanin-rich skin and textured hair. Ekene includes botanical ingredients studied for antibacterial and antimicrobial properties to help support a clean, balanced, healthy scalp while you wear your protective style. Massaging a few drops into your parts also nourishes the scalp and supports the conditions your hair needs to thrive.

Ingredient Spotlight: The Botanicals Behind the Nk&Co Hair Growth Routine

We get asked all the time what actually makes a scalp product worth using under braids. Our hair growth routine is built on three products that each do a different job: a light scalp oil, a richer hair food and a soothing serum. Below are the key ingredients in each and what the research says about them. Most of these studies were done in labs, in animals, with oral supplements or with different products, so think of this as why we chose these ingredients, not a promise of results.

"Ekene" Hair Oil: The Lightweight Scalp Oil

"Ekene" Hair Oil is a lightweight, plant-based scalp and hair oil for a scalp that feels dry or uncomfortable and hair that feels dry, brittle or rough. It absorbs fast without weighing down braids, twists, locs or wigs, and has a fresh, herbal, gently minty scent with no added synthetic fragrance. Here are its key ingredients:

Tea tree oil. Tea tree is one of the most studied botanicals in scalp care. Its main active compound, terpinen-4-ol, has been studied for antibacterial, antifungal and anti-inflammatory properties (Carson et al., 2006). In a randomized study of 126 people with mild to moderate dandruff, a 5% tea tree oil shampoo used daily for four weeks improved flaking scores by 41 percent, compared with 11 percent for placebo, with improvements in itchiness and greasiness too (Satchell et al., 2002). Researchers connected this to tea tree's activity against Malassezia (then called Pityrosporum ovale), a yeast associated with flaking.

Neem. Neem has a long history in traditional care and contains limonoid compounds such as azadirachtin and nimbidin. A 2022 review summarized lab research on the antibacterial and antifungal activity of neem extracts and compounds, while noting that more studies in people are still needed (Wylie and Merrell, 2022).

Peppermint. Menthol gives peppermint its cooling, tingly feel on the scalp. In a 2014 study in mice, a 3% peppermint oil applied topically for four weeks increased hair follicle number and depth more than saline, jojoba oil or 3% minoxidil in the same study (Oh et al., 2014). This was animal research and has not been shown in people, so we think of peppermint as a refreshing, scalp-conditioning ingredient, not a growth guarantee.

Eucalyptus. Eucalyptus oil is rich in 1,8-cineole (eucalyptol). A 2023 review describes lab research on its antimicrobial activity against several bacteria and fungi (Pries et al., 2023). It also adds a clean, fresh scent.

Castor oil. Castor oil is made mostly of ricinoleic acid, which showed anti-inflammatory effects when applied topically in lab and animal research (Vieira et al., 2000). Its thick texture also helps seal moisture into strands.

Jojoba, avocado and grapeseed oils. Jojoba is technically a liquid wax that closely resembles the natural oil your scalp produces, so it feels light instead of greasy. A dermatology review of plant oils covers jojoba for its skin barrier support (Lin et al., 2017). Avocado oil adds richness to help condition dry strands, and grapeseed keeps the blend lightweight and easy to spread on your parts.

Why this matters under protective styles. Under braids and locs, your scalp is covered, washed less often and sitting in sweat and product for weeks. After an ACV rinse helps clear residue and bring your scalp back toward its slightly acidic pH, a light layer of Ekene with these botanicals helps replenish moisture and support a healthy, balanced scalp until your next wash.

"Erinma" Hair Food: The Moisture and Sealing Step

"Erinma" Hair Food is our nutrient-rich hair food, made to soften and condition hair, help with detangling and seal in moisture between oilings. Where Ekene is the light everyday scalp layer, Erinma is the richer step for your strands, ends and edges. Here are its key ingredients:

Fenugreek. Fenugreek seed has a long history in home hair care in India and beyond. In a small randomized, placebo-controlled trial of 60 people with split ends, a topical fenugreek seed gel used for two months reduced hair splitting significantly more than placebo, and the fenugreek group also saw less dryness and fragility (Hajizadeh et al., 2022). Separately, a lab study found fenugreek leaf extract was active against Malassezia furfur, a yeast associated with flaking (Kulkarni et al., 2020). That was lab research with a different part of the plant, so we see it as promising, not proven on the scalp.

Shea butter. Shea is a rich, softening butter that helps seal moisture into dry strands. Researchers isolated triterpene compounds from shea fat that showed anti-inflammatory effects when applied topically in mice (Akihisa et al., 2010). This was animal research, but it helps explain shea's long reputation for comforting dry skin.

Wheat germ oil and vitamin E. Wheat germ oil is naturally rich in vitamin E, an antioxidant. In a small randomized trial, volunteers with hair loss who took 100 mg of tocotrienols (a form of vitamin E) by mouth daily for eight months had a 34.5 percent increase in hair count in a measured scalp area, compared with a 0.1 percent decrease in the placebo group (Beoy et al., 2010). That study used oral supplements, not a topical product, so we include wheat germ and vitamin E for their antioxidant, conditioning role, not as a growth promise.

Hempseed oil. Hempseed oil is a balanced source of omega-6 and omega-3 fatty acids. In a 20-week randomized crossover study, people with atopic dermatitis who took hempseed oil as part of their diet reported less skin dryness and itchiness than with olive oil (Callaway et al., 2005). That was dietary use, but it shows why hempseed is valued for dry-feeling skin.

Castor, avocado, jojoba and ylang ylang. Castor adds slip and helps seal in moisture, avocado adds richness for dry strands, jojoba keeps the blend from feeling greasy, and ylang ylang adds a soft floral note.

"Chizaram" Anti-Itch Serum: The Soothing Step

"Chizaram" Anti-Itch Serum is a lightweight, plant-based scalp and skin serum for a scalp that feels dry, tight, flaky or itchy. It sinks in without weighing down protective styles, with a fresh, minty, herbal scent over a soft floral base. If itching is your biggest struggle under braids, this is the step to add between washes. Here are its key ingredients:

Calendula. A 2023 review summarizes lab and animal research linking calendula flower compounds, especially triterpenoid esters such as faradiol esters, to anti-inflammatory activity (Shahane et al., 2023). That is a big part of why calendula is a classic in soothing skin care.

Lavender. Lavender has been studied for antibacterial and antifungal properties, though reviewers describe the evidence as promising but still developing (Cavanagh and Wilkinson, 2002). It also adds a calming scent.

Chamomile. Chamomile flowers contain terpenoids and flavonoids, and chamomile has long been used to calm inflammation and comfort skin. A review notes that more preclinical and clinical research is still needed to confirm these benefits (Srivastava et al., 2010).

Peppermint. Beyond its cooling feel, peppermint has some human data on itch. In a study of 50 people with chronic itch linked to liver, kidney or diabetic conditions, those who applied peppermint oil twice daily for two weeks reported more itch relief than those who applied petrolatum (Elsaie et al., 2016). That study was on body skin, not the scalp, and used a different product.

Tea tree. The same tea tree research behind Ekene applies here, including the dandruff shampoo study that showed improvements in flaking and itchiness (Satchell et al., 2002).

Basil. Lab testing of sweet basil essential oil found activity against several bacteria and fungi, including Staphylococcus aureus (Joshi, 2014). This was lab research only.

Sesame, avocado, olive, hemp, wheat germ and apricot kernel oils. These carrier oils give the serum its light, moisturizing base, with ylang ylang adding a soft floral note.

Bonus Tip: Nkechi Body Butter Works on Hair Too

"Nkechi" Body Butter is made for dry skin, but its whipped, water-free blend of shea and mango butters, castor oil, and peppermint, tea tree and eucalyptus also works on hair. Smooth a small amount over your ends to help seal in moisture, or warm a little between your palms to soften dry-feeling braids and edges. A little goes a long way, and keep it off your parts so it does not build up on your scalp under your style.

A quick note: essential oils can irritate sensitive skin. Patch test first, apply only to intact skin and stop using any product that causes burning or redness.

How to use a scalp oil with braids

  1. Apply a few drops directly to your parts two to three times a week.
  2. Massage gently with your fingertips to spread it without frizzing your braids.
  3. Pair it with a diluted ACV rinse every one to two weeks to keep buildup in check.
  4. Less is more. A light layer works better than heavy product that traps residue.

Frequently asked questions

Is synthetic braiding hair toxic?

Independent testing has found contaminants such as lead, benzene and other VOCs in many braiding hair products, including synthetic, human and plant-based hair. Levels vary widely by brand. Experts recommend choosing brands that publish test results, avoiding heat during installs and taking breaks between styles.

Does an ACV rinse remove chemicals from braiding hair?

An ACV soak helps lift the alkaline coating and surface residue that commonly cause itching. It does not remove every chemical, such as flame retardants or dyes, so it works best alongside choosing better hair.

How do I stop my scalp from itching under braids?

Pre-wash your braiding hair, start with a clean scalp, avoid overly tight braids, cleanse your scalp every one to two weeks with a diluted rinse and use a light scalp oil on your parts. See a dermatologist if itching comes with bumps, sores, burning or swelling.

How often can I use an ACV rinse on my scalp?

For most people, a well-diluted rinse every one to two weeks is plenty. Stop if you notice burning, increased itching, redness or breakage, and avoid it on broken or inflamed skin.

Where can I get ACV braiding hair washes near Houston?

Arinke Hair & Loc Lounge at 17627 Beechnut St, Richmond, TX 77407 offers ACV braiding hair washes for its clients.

Can scalp oil help my hair grow while I wear braids?

A healthy scalp supports healthy hair. A light, plant-based oil with antimicrobial botanicals can help keep your scalp balanced and nourished under protective styles, which supports the conditions your hair needs to thrive.

When to see a professional

If your scalp shows red bumps, sores, burning, swelling, oozing, or itching that worsens instead of improving, take the style down and talk to a dermatologist. You can also report reactions to the FDA through MedWatch and to the Consumer Product Safety Commission at SaferProducts.gov. A professional stylist can help assess tension, installation technique and whether a style is right for your scalp.
