Majestic Protein Therapy ( with Collagen and Argan Oil) is the latest and most advanced protein formula to remove frizz, reduce volume and deeply restore damaged, without the use of harsh chemicals. It can be applied on previously straightened hair, colored or de-colored hair, and hair that has been treated with any other chemicals. The healthier the condition of the hair, the better the final result will be. The volume reduction is progressive and cumulative, making the hair easier to work on, besides providing shine and natural look to the strands. For very thick, curly hair, previously treated with a relaxer, applying this treatment will provide an amazing result and a very natural look.
