Infused with Krystal Water Complex, 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, its the same leave-in wonderful as the Purify Plus Conditioning Treatment, just a hushed version that also adds volume. Its neutralizer, protectant, bodifying treatment and sealer all in one barely-there but cant go without formula.
