PURIFY PLUS LITE LEAVE-IN CONDITIONING TREATMENT Infused with our Krystal Water Complex, our Purify Plus Lite whispers sweet nothings into those thinner, fine strands by neutralizing everyday tap water and barricading the hair shaft from the intrusion of harsh chemicals. With a kiss of keratin and delicate PH balance, it’s the same leave-in wonderful as our Purify Plus Conditioning Treatment, just a hushed version that also adds volume. It’s neutralizer, protectant, bodifying treatment and sealer all in one barely-there but can’t go without formula.
