Detailed answer

Allergies to skincare products can cause skin reactions like redness, itchiness, or rash, but they do not directly cause hair sunburn. Hair sunburn occurs when the hair shaft and scalp are exposed to excessive sunlight, leading to dryness, damage, and sometimes even loss of hair color. It is mainly a result of UV radiation and not related to allergies. However, certain ingredients in skincare products, such as fragrances or sunscreens, can cause sensitivity to the scalp and skin, making them more prone to sunburn. It is important to protect both your skin and hair from the sun by using sunscreen with hair protection or wearing a hat while outdoors. If you suspect an allergic reaction, discontinue use of the skincare product and consult a dermatologist for further evaluation.
