Yes, reactions to braiding hair are a common experience, often leaving the scalp intensely itchy and inflamed shortly after installation. This issue is typically a form of contact dermatitis, which is an irritation of the skin, rather than a traditional IgE-mediated allergy to the synthetic fiber itself. The discomfort arises from direct physical contact with chemical substances used during the manufacturing process of the hair extensions. Understanding the source of this irritation is the first step toward preventing it for future protective styles.
The Chemical Culprit: Why Braiding Hair Causes Reactions
The primary source of scalp irritation from synthetic braiding hair, such as Kanekalon, is the alkaline chemical coating applied to the fibers. This coating is added during manufacturing to help prevent mold growth and enhance the hair’s texture and sheen. The chemical residue creates an alkaline environment with a high pH, which disrupts the natural, slightly acidic pH balance of the scalp, leading to irritation.
This reaction is medically classified as irritant contact dermatitis, meaning the chemical substance directly damages the skin tissue. The alkaline nature of the coating causes the burning and itching sensation because the skin functions best at a pH of around 4.5 to 5.5. True allergic contact dermatitis is less common but can occur due to other processing chemicals like dyes or fixatives. Sweating and heat can worsen the problem by causing the alkaline residue to leach out of the synthetic hair and onto the scalp and neck.
Recognizing the Signs of Scalp Irritation
Symptoms of irritation from braiding hair typically appear quickly, often within 24 to 48 hours after the braids are installed. The most common sign is intense, persistent itching, often accompanied by noticeable redness and inflammation along the hairline and across the scalp.
Many people also develop small, raised bumps, known as papules, or a visible rash on the scalp, neck, or forehead. While most reactions are moderate and localized, monitoring the severity of the symptoms is important.
A more severe reaction may involve the development of blisters, weeping, or a painful, burning sensation. These advanced signs suggest a significant inflammatory response or a potential secondary bacterial infection from excessive scratching. If symptoms include swelling of the face, difficulty breathing, or widespread hives, immediate medical attention is necessary, as this may indicate a severe allergic reaction.
Prevention and Treatment Strategies
Preventing the irritating reaction starts before installation with a pre-treatment process designed to neutralize the alkaline coating. This involves soaking the synthetic hair in an acidic solution to lift and remove the irritant chemical residues. A highly effective method is an apple cider vinegar (ACV) rinse, using a mixture of one part ACV to three or four parts warm water.
The hair should soak for 15 to 30 minutes, or until a visible white film appears on the water, indicating the alkaline chemical has been successfully removed. After the soak, the hair must be thoroughly rinsed with cool water and allowed to air dry completely before installation. This preparatory step significantly reduces the likelihood of developing irritant contact dermatitis.
If an active reaction is already occurring, removing the braids is often the most definitive solution. For mild to moderate itching, over-the-counter anti-itch treatments, such as hydrocortisone cream or anti-itch braid sprays containing soothing ingredients like tea tree oil, can offer relief. Oral antihistamines can also help calm the body’s inflammatory response and reduce persistent itching.
If symptoms are severe, persistent, or show signs of infection like pus or blistering, consult a dermatologist for professional care. A physician can prescribe stronger topical steroids to reduce inflammation and may recommend antibiotics if a secondary infection is suspected. The best long-term strategy involves using hypoallergenic or pre-washed synthetic hair options for future protective styles to bypass the chemical exposure altogether.
