Detailed answer

Hair vitiligo is a condition characterized by the loss of pigmentation in the hair follicles, resulting in white patches. It is an autoimmune disorder that occurs when the immune system attacks the melanocytes, the cells responsible for producing pigment. Allergies to skincare products, on the other hand, are a hypersensitivity reaction of the immune system to specific ingredients in the products. While both conditions can affect the skin, they have different causes. Allergies to skincare products can lead to skin irritation or inflammation, but they do not directly cause hair vitiligo. Hair vitiligo is believed to be influenced by genetic factors, autoimmune processes, and environmental triggers, but the exact cause is not fully understood.
