What is the best hair treatment for dry hair?

Cysteine is a natural absorbent that conditions hair by penetrating the hair shaft. It reduces frizz and prevents hair from further damage and drying. The cysteine complex, a non-essential amino acid found in keratin (the hair protein), is used in this treatment. Hair is washed and dried first. Small pieces of hair are treated with the cysteine complex. The roots of the hair are not touched. Your hair will be wrapped in a plastic sheet for roughly 45 minutes after treatment. After that, the cysteine compound is heated to activate it. For a sleek finish, your hair is blow-dried again and flat ironed. Your hair is shampooed with suitable products like Moroccanoil and conditioned again after the treatment. You’ll notice a difference in your hair once it’s dry.
