Arrow Product details

A lightweight serum formulated with optimized high and low molecular weight Hyaluronic Acids, which helps to hydrate, reduce frizz and brittleness to improve shine, whilst helping to protect hair from the impact caused by environmental pollution. 

Hyaluronic acid is a classic ingredient, traditionally known in skincare for its highly hydrating properties. Lack of hydration in the hair can be caused by several factors, 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. 

All hair types, even those with sensitive skin. 

2% RESISTHYAL™**containing optimized high and low molecular weight Hyaluronic Acids, helps to hydrate, reduce frizz and brittleness to improve shine, whilst helping to protect hair from the impact caused by environmental pollution.

HOW TO APPLY: Use as a post wash treatment. Shake bottle first, then pour onto the palm of your hand and work through wet or dry hair. Apply enough product to thinly coat all of your hair. Leave on and style as usual. For best results, apply 1 - 2 times per week. HOW TO LAYER YOUR HAIRCARE ROUTINE: Hyaluronic Acid Hydrating Hair Treatment works alongside all other The INKEY List hair and scalp products. If using Peptide Volumizing Hair Treatment or PCA Bond Repair Hair Treatment, use Hyaluronic Acid Hydrating Hair Treatment afterwards. Apply before using Shea Oil Nourishing Hair Treatment, as the last step in your hair routine. For all other The INKEY LIST hair treatments, because of the role they play and the way they work on your hair, these can be applied in any particular order.
