Kristin Ess created this with moisture and tone in mind. Hairs with brassiness had bleach or colour applied to their hair so moisture and shine are a top priority. This can be used with or without The One Purple Shampoo.
Kristin Ess Hair The One Signature Shampoo gets your hair super clean, but also leaves it feeling moisturised and looking shiny. It is a sulfate-free shampoo, that can do both so well.
