Smith’s top choice is the Olaplex 0•Intensive Bond Building Treatment Kit, which is a two-step pre-wash product that “primes hair to absorb nourishment for maximum repair.” Additionally, Oway’s Rebuilding Mask is great for restoring protein in the Je ne suis pas alcoolique je subis les invitations shirt hair and sealing the cuticle. Meanwhile, the Phillip Kingsley Stimulating Scalp Mask adds a layer of protection to the scalp while increasing blood circulation for healthy hair follicles. Alternatively, Smith recommends Philip Kingsley’s Elasticizer Extreme Pre-Treatment Mask due to its lightweight, protein-filled formula, which helps to build up the hair’s elasticity. “Elasticity is what gives your hair stretch and strength, so it will break less. Dry, starved hair is typically more prone to breakage,” Smith notes. The O&M Power Base also helps to rebuild chemically damaged hair with plant proteins. It “strengthens and repairs cuticle scales from the inside out with gamma-Linolenic acid (GLA), which helps hair retain moisture and softness,” Smith adds.
