Detailed answer

Allergies to skincare products typically manifest as skin reactions such as rashes, itching, or inflammation. These reactions are localized to the area of contact with the product. Hair straightness is determined by the structure and genetics of the hair follicle, as well as external factors like heat or chemical treatments. It is unrelated to allergies to skincare products. However, if a person experiences an allergic reaction on their scalp due to a skincare product, it may indirectly affect the hair by causing scalp irritation or discomfort, which could potentially lead to hair loss or breakage. It is important to identify and avoid allergens in skincare products to maintain healthy skin and hair.
