Although milder for the scalp, it leaves calcium mineral residues on the hair shaft, making it drier, brittle, and dull [4, 11-14].
STRAIGHTENING MY HAIR is typically a two-day affair. I wash all the product out the night before and load my hair with hydrating protectants. I let it air-dry, then I braid it before bed so that the next day, the curls are looser and easier to work through. Then, and only then, can I go in with a flat iron.
