Nair removes hair from the skin by dissolving the hair shaft. It works on the skin’s surface so hair may grow back quickly, usually within four days. The results last a little longer than shaving.
Nair and other depilatories can be safe, painless methods for hair removal, but the chemicals may irritate the skin if they are left on too long. A reaction may also occur when applying Nair to sensitive areas, such as the face and genitals. To avoid a reaction, read the instructions before the using the product. Test Nair on a small patch of skin to test for a reaction to the cream.
