Argan oil crystals 

The liquid crystals in the Renée Blanche ARGAN oil treatment line protect your hair from external agents, restoring shine and vigor.
This specific treatment detangles and rehydrates brittle, lifeless hair from root to tip, strengthening the hair fibre all the way to the tips.
To apply, slide a small amount into the palm of your hand and massage evenly along the entire length of the hair, working all the way to the tips. Rub more vigorously at the tips, closing any split ends.
