CoileenSodium Lauryl Sulfate
What it is
A powerful surfactant and foaming agent found in many shampoos and cleansers. It is the ingredient responsible for the rich lather most people associate with 'getting clean.'
Why it matters for curly hair
Sodium lauryl sulfate is one of the harshest cleansers used in hair products. It strips the hair and scalp of natural oils, leaving curls dry, frizzy, and prone to breakage. For curly hair, which is naturally drier than straight hair because scalp oils can't travel down the bends of the strand, this stripping effect is especially damaging and can undo months of moisture work in a single wash.
