Hair colour allergy, Facts and suggestions. Dr Sandesh Gupta Dermatologist Delhi.

Описание: Hair color allergies can cause irritation or reactions on the scalp due to sensitivity to certain chemicals in the hair dye. The most common allergen in hair dyes is **paraphenylenediamine (PPD)**, but other ingredients like ammonia, peroxide, or resorcinol can also cause issues. Here's a guide to managing and addressing hair color allergies:

---

*Symptoms of Hair Dye Allergy*
Itching, redness, or swelling of the scalp, face, or neck.
Burning or stinging sensations.
Rash or hives.
Severe cases may involve blisters, oozing, or even breathing difficulties (rare).

*Steps to Address a Hair Dye Allergy*
1. *Stop Using the Product Immediately*
Rinse the dye off your scalp and hair thoroughly with lukewarm water and a mild shampoo.

2. *Apply a Soothing Agent*
Use a mild, fragrance-free moisturizer or aloe vera gel to calm the skin.

3. *Use an Antihistamine or Steroid Cream*
Over-the-counter hydrocortisone cream can reduce inflammation.
Oral antihistamines like loratadine or diphenhydramine may help with itching and swelling.

4. *Seek Medical Attention*
If symptoms worsen or you experience severe swelling, blisters, or difficulty breathing, consult a dermatologist or allergist immediately.

5. *Patch Test Before Dyeing Again*
Always test the dye on a small patch of skin (like behind your ear) 48 hours before applying it to your hair.

*Alternative Options*
**PPD-Free Hair Dyes**: Look for brands labeled as hypoallergenic or free of harsh chemicals.
**Natural Options**: Henna or plant-based dyes can be gentler alternatives but still require a patch test.
**Professional Coloring Services**: A dermatologist or allergist can guide you toward safer options or refer you to a professional salon experienced in handling sensitive scalps.
