Sulfate-free shampoos are essential allies for prolonging the benefits of a keratin treatment and for general hair care. These shampoos are gentle and do not remove keratin, which helps to keep hair soft and frizz-free for longer after treatment.
In addition to their post-keratin effectiveness, sulfate-free shampoos are less damaging to hair in general. They do not remove natural oils or dry out the scalp, making them ideal for all hair types, even if you have not had a straightening treatment.
Arual Free shampoo and conditioner are excellent examples of sulfate-free products that offer hydration, softness and shine to your hair. By incorporating these products into your routine, you will keep your hair healthy and beautiful for the long term, preserving the benefits of keratin and avoiding unnecessary damage. Sulfate-free shampoos are an investment in the health and beauty of your hair.
