Hair Alchemy Fortifying Treatment Serum is a sheer, fast-absorbing serum that improves tensile strength and elasticity and prevents breakage. This treatment elixir combines a curative blend of chia seed, bio-fermented bamboo leaf and plant-based protein that penetrate the hair cortex to build strength from within, while phytoceramides and cotton seed extract shield and fortify fragile strands. Oribe's Signature Complex defends hair from oxidative stress, photoaging and keratin deterioration. Hyaluronic Acid Complex rehydrates from within to deliver a surge of moisture and increase elasticity.
