braidbetter is clinically tested to be hypoallergenic, safe for sensitive skin, and suitable for individuals with eczema-prone skin. It has also been lab tested as microbiome-friendly. The ingredients used in its manufacturing are carefully selected to ensure they are biodegradable, skin-safe, and environmentally responsible.

In contrast, Kanekalon is a modacrylic fiber commonly used in synthetic braiding hair. Modacrylics are synthetic fibers with a high acrylonitrile content, and commercial braiding hair products may also include other polymers such as PVC-related materials, PET, polypropylene, or nylon, depending on the formulation. (EPA – Acrylic and Modacrylic Fibers Production).

Recent investigations by organizations such as the Silent Spring Institute and Consumer Reports have analyzed various synthetic, human, and plant-based braiding hair brands and identified compounds associated with potential health risks, including carcinogens and endocrine disruptors.

Why Is an Itchy Scalp with Braids So Common?

When evaluating the root cause of "the itch" associated with braiding hair, it is important to recognize that irritation is multifactorial. The source of itching may stem from the fiber itself, residual chemicals on the fiber, or the installation method. Not all cases are chemically driven; mechanical factors such as tension, occlusion, sweating, and friction can also exacerbate scalp irritation from braids, particularly for individuals with sensitive or atopic skin. Working with an experienced stylist can help minimize tension-related irritation. Find a braider near you who works with braidbetter.

Chemicals in Braiding Hair: Residual Processing Agents

One common cause of an allergic reaction to braiding hair is the presence of residual processing chemicals on the fiber surface. Research on textile-related dermatitis shows that irritation is more frequently linked to these chemicals than to the base polymer itself.  Potential irritants include:

• Dyes and finishing agents

• Adhesives

• Formaldehyde-based resins

• Flame-retardant additives

These materials can act as sensitizers or irritants depending on their composition and residual levels.

Flame Retardants Found in Braiding Hair

Flame-retardant additives, including tributyl phosphate, triphenylphosphine oxide, tributylphosphine oxide, and 2,4,6-tribromophenol, were detected across multiple synthetic and bio-based braiding hair samples. These chemistries have been associated with contact sensitivity and irritation in some individuals.

Aromatic Amines, Organotins, and Other Sensitizers

In addition, aromatic amines, organotin compounds, and benzyl chloride, all of which have been linked to skin sensitization, were identified in various synthetic and human hair samples. Aromatic amines are most commonly associated with oxidative and disperse dye systems used in the processing of both human and synthetic braiding hair.

What Was Detected in braidbetter Samples?

In the interest of full transparency, braidbetter samples were also evaluated as part of these independent studies.

Silent Spring Institute tested two braidbetter samples. The following compounds were detected in only one of the two samples: diethyl phthalate, tributyl phosphate, phenol, and bis(2-ethylhexyl) ester hexanedioic acid. The following compounds were detected in both samples: chloromethyl octanoate, chloromethyl hexanoate, and bis(2-ethylhexyl) phthalate.

In a separate analysis, Consumer Reports evaluated one braidbetter sample in triplicate. They detected trace levels of the following compounds in each replicate: lead, dichloromethane, naphthalene, 4-isopropyl toluene, acetone, and benzene. The following compounds were detected in only one of the three replicates: 2-butanone, carbon disulfide, and chloroform.

We remain committed to transparency and to continuously improving the safety and quality of our products as we work toward becoming the cleanest option for braiding hair on the market. In response to these findings, we have already initiated a comprehensive investigation into the root causes of these detections and are actively implementing reformulation and process improvements.

Can Fiber Friction Alone Cause Scalp Irritation from Braids?

Physical properties of the fiber itself can also play a significant role. Even in the absence of chemical sensitization, synthetic fibers may cause irritant contact dermatitis due to:

• Friction and roughness against the scalp

• Poor moisture management

• Prolonged contact with the scalp and neck

This means that even braiding hair without chemicals can still cause irritation if the fiber surface is coarse or poorly manufactured, making material quality a key factor for anyone seeking itch-free braiding hair. Proper aftercare also plays a role; see the braidbetter care guide for tips on keeping your scalp comfortable throughout your wear.

Choosing Braiding Hair for Sensitive Scalp: What to Look For

For those prone to an itchy scalp with braids, choosing hypoallergenic braiding hair that has been clinically tested can make a meaningful difference. Look for products that are:

• Clinically tested for skin safety (not just self-reported claims)

• Free of known sensitizers such as flame retardants and aromatic amines

• Microbiome-friendly and suitable for eczema-prone skin

• Made from biodegradable, skin-safe materials

braidbetter meets all of these criteria, offering a safe braiding hair option that addresses both chemical and mechanical sources of irritation.

What Still Needs to Be Studied

To better understand and isolate the root cause of irritation, a follow-up study is recommended to evaluate differences across multiple brands, focusing on:

1. Variability in residual surface chemicals and finishing agents

2. Differences in fiber morphology, including roughness and frictional properties

 Relevant research questions include:

• Does removal of surface chemicals (via pre-wash) significantly reduce scalp irritation from braids?

• Are specific chemical classes (e.g., dyes, organotins, flame retardants) driving irritation?

• Does fiber friction and roughness independently cause irritation in the absence of chemicals?

• Is irritation primarily irritant rather than allergic in most users?

• What is the interaction between braid tension and chemical exposure?
