Hairstory New Wash can be worth it for those seeking a sulfate-free alternative to traditional shampoo. It cleanses the scalp and hair using oils and essential oils, aiming to maintain natural moisture and reduce reliance on styling products. Consider your hair type and budget before deciding if its unique approach aligns with your needs.

There isn't one single brand universally used by most salons. Common professional brands found in salons include L'Oréal Professionnel, Redken, Wella Professionals, and Aveda, but the specific brands used vary greatly depending on the salon's focus and clientele.

The healthiest option depends on individual hair type and needs, but generally, sulfate-free cleansers or co-washing products are considered gentler. These options help retain natural oils and prevent dryness, promoting healthier hair overall. Experiment to find what works best for your hair.
