Detailed answer

Allergies to skincare products are caused by immune responses to specific ingredients in the products. Hair and scalp melanoma, on the other hand, is a type of skin cancer that develops from melanocytes, the cells that produce pigment in the skin. The main risk factors for melanoma include genetic predisposition, intense and intermittent sun exposure, fair skin, and a history of sunburns. While it is important to be aware of any potential allergic reactions to skincare products and discontinue their use if symptoms occur, there is no scientific evidence to suggest that allergies directly cause hair and scalp melanoma.
