Over 30? The new Living Proof Timeless collection is for you! Have you ever used a pre-shampoo before? Basically, they’re moisturizing treatments, like hair masks, oils and butters, that you apply to your hair while it’s wet or dry before you hop into the bath or shower to shampoo and/or condition. The extra step adds shine, and it’s also supposed to make the Timeless shampoo and conditioner work better. We carry travel sizes of all the products too!
