Does nair disappear leg and or arm hair forever?

Nair does not remove leg or arm hair permanently. Nair is a depilatory cream that temporarily removes hair by chemically dissolving the shaft of the hair, it does not target the root of the hair and therefore does not prevent future growth.

For permanent hair removal, methods like laser hair removal or electrolysis are more effective as they target the root of the hair and permanently destroy the hair follicle, preventing regrowth.
