Brand: Philip Kingsley

Density Thickening Shampoo contains unique hyper-branched polymers and hydrolyzed pea peptides to instantly volumize hair without causing dryness. The sulfate-free formula restores and strengthens strands from deep within the cortex, while BHAs gently exfoliate the scalp, resulting in reduced breakage and an optimal scalp environment. Formulated for anyone experiencing hair loss or thinning, as well as those with fine, fragile hair prone to breakage.

- Hyper-branched polymers increase volume by transforming from a flat structure on wet hair, to a hexagonal shape upon drying, pushing the hair apart to deliver lasting volume and healthy strands
- Hydrolyzed pea peptides increase strand thickness and provides antioxidant, hydrating and smoothing benefits
- Strengthening molecules strengthen hair from deep within the cortex to reduce hair breakage
- Salicylic Acid is a BHA which gently exfoliates and stimulates the scalp, helping to reduce sebum (oil) and create the best environment for optimal hair growth
- Cruelty-free. Scientifically-tested
