Hyaluronic acid is a classic ingredient, traditionally known in skincare for its highly hydrating properties. The The INKEY List Hyaluronic Acid Hydrating Hair Treatment formulation contains optimized high and low molecular weight hyaluronic acids, which not only hydrates your hair, but also works to reduce frizz, brittleness and protect it against pollution.

Lack of hydration in the hair can be caused by a number of things, including over washing, water temperature being too high, using heated tools without heat protection or humidity. When your hair becomes dry, the hair cuticle is rough and open, causing hair to lose moisture and become frizzy.

Similarly to its ""cousin"" in skincare, we'd recommend everyone to use this, as it's a fantastic multi-tasking lightweight serum, especially indicated for those in need to tame frizz but also who live in big cities and want to protect their hair against pollution.

Key ingredients:

- 2% RESISTHYAL™

- 1% BETAINE

- 1% PANTHENOL

DIRECTIONS
