Your head might feel weird after dying your hair due to a variety of reasons, ranging from mild skin irritation to a more serious allergic reaction to the chemicals in the hair dye.
Potential Causes for a Weird Feeling After Hair Dyeing:
-
Chemical Irritation: Hair dyes contain chemicals like ammonia, peroxide, and paraphenylenediamine (PPD) that can irritate the scalp. This is the most common cause of a "weird" feeling. The sensation could be:
- Tingling or burning: A mild chemical reaction can cause a slight burning or tingling feeling, particularly if you have sensitive skin.
- Itchiness: The chemicals can disrupt the scalp's natural pH balance, leading to itchiness.
- Dryness: Hair dyes can strip the scalp of its natural oils, causing dryness and a tight feeling.
-
Allergic Reaction (Contact Dermatitis): Some individuals are allergic to components in hair dye, especially PPD. This can cause a more pronounced reaction than simple irritation. Symptoms might include:
- Intense itching: More severe than simple irritation.
- Redness and rash: Often appearing on the scalp, hairline, ears, neck, and even eyelids.
- Swelling: In severe cases, swelling of the scalp, face, or eyelids can occur.
- Burning sensation: A stronger and more painful burning than typical irritation.
-
Scalp Sensitivity: You may simply have a sensitive scalp that reacts more readily to the chemicals in hair dye, even if you're not truly allergic.
-
Over-Processing: If the dye was left on for too long, or if you recently permed or relaxed your hair, your scalp may be more sensitive to the chemicals, leading to irritation.
-
Product Buildup: Even after rinsing, some dye residue or other chemicals from the process can remain on the scalp and cause irritation or a "weird" feeling.
What to Do:
-
Rinse Thoroughly: Immediately rinse your hair and scalp thoroughly with cool water to remove any remaining dye.
-
Use a Gentle Shampoo and Conditioner: Opt for sulfate-free and fragrance-free products to minimize further irritation.
-
Apply a Cold Compress: A cold compress can help soothe an irritated scalp.
-
Avoid Scratching: Scratching can worsen the irritation and potentially lead to infection.
-
Take an Antihistamine: If you suspect an allergic reaction, an over-the-counter antihistamine (like Benadryl) can help relieve itching and reduce inflammation. Note: Consult a doctor or pharmacist before taking any new medication.
-
See a Doctor: If your symptoms are severe (significant swelling, difficulty breathing, severe rash), or if they don't improve after a day or two, seek medical attention immediately. You may need a prescription-strength antihistamine or corticosteroid cream.
-
Patch Test: Before dying your hair again, perform a patch test to check for allergic reactions. Apply a small amount of the dye to a discreet area of skin (like behind your ear) 48 hours before dyeing your hair. If you develop any redness, itching, or swelling, do not use the dye.
-
Consider Alternatives: Explore gentler hair dye options, such as semi-permanent dyes or dyes that are free of ammonia and PPD. Talk to your stylist about options that might be less irritating for your scalp.
By understanding the potential causes and taking appropriate steps, you can manage a weird feeling after dyeing your hair and prevent future occurrences.
