About Ferrous Sulfate

Ferrous Sulfate is an inorganic salt.[1] In cosmetics, it is used to provide a temporarily tightening, astringent sensation to the skin or scalp and to leave the skin surface feeling fresh.[3] In Korea, it may be used at up to 6% in non-oxidative hair dyes, but it cannot be used in oxidative hair dyes.[2]
