If your end goal is a fuller head of hair, Keranique's Micro-Exfoliating Follicle Revitalizing Mask is the pre-shampoo product for you. For starters, it contains vicia faba seed extract, an ingredient that helps promotes stronger and fuller hair. It also contains Biotinoyl Tripeptide-1, which sequesters DHT (the hormone/steroid responsible for balding). Additionally, the apricot seed powder gently exfoliates your scalp while jojoba oil nourishes. Be prepared for the cleanest and softest hair of your life.
Though you may not associate elasticity with hair health, the truth is that healthy hair is flexible and stretchy when wet. Unhealthy hair, on the other hand, is brittle and breaks off. Philip Kingsley's Elasticizer Pre-Shampoo Treatment is formulated with natural castor oil and olive oil to promote moisture, bounce and shine, silicones to smooth the cuticle, elastin to strengthen and promote elasticity, and glycerine and glycol to help hair better retain moisture.
This pre-shampoo treatment by Living Proof is specifically formulated for women with graying hair, color-treated hair or chemically treated hair. It boasts the brand's "shampoo-activated color-seal technology" and UV absorbers, which together help lock in color while strengthening the shaft. It also repairs damage and reduces further breakage, and is intended for usage before every shampoo.
