Developer
A Developer in the beauty industry, also known as a processing solution specialist, is someone who works with hair chemicals and treatments. They mix and manage the chemicals used in hair coloring, perming, and other beauty treatments. Think of them as the "behind the scenes chemist" who ensures that hair products work correctly and safely. They might work for beauty product companies creating new formulas, in salons mixing custom solutions, or in training roles teaching others about proper chemical usage in hair treatments.
