If your scalp is very reactive or you have known sensitivities to fragrance or cosmetic preservatives, a cautious approach is sensible. This mask is formulated primarily for the hair lengths and ends, not the scalp. Therefore, the safest practice is to apply it only from the mid-lengths down, avoiding direct contact with the scalp skin.
Before full use, it is highly recommended to perform a patch test. Apply a small amount of the product to a discreet area of skin, such as the inside of your elbow or behind your ear, and leave it for 24 hours to check for any adverse reaction. The formula contains common conditioning agents like cetearyl alcohol and cetrimonium chloride, which are generally well-tolerated but, like any cosmetic ingredient, can cause reactions in predisposed individuals. If you have a diagnosed scalp condition, this product is meant for cosmetic care of the hair fiber and is not intended to treat medical concerns.
