A depilatory product is a type of product used to remove unwanted hair from the body. The two most common crossword solutions for this term are NEET and NAIR, both of which are four-letter words. NEET is a brand of depilatory cream that is applied directly to the skin and left on for a few minutes before being washed off. NAIR is a brand of depilatory lotion that is applied to the skin and left on for a few minutes before being wiped off with a damp cloth. Both products work by breaking down the proteins in the hair, making it easier to remove.
