Our panel was impressed with its lightweight feel, with the majority noticing thicker hair as a result of using it. Less shedding was reported, with many testers seeing significant regrowth.

Revitalizer, £53 81/100

Designed around Ayurvedic principles, this scalp-stimulating treatment seeks to reduce breakage-caused hair loss by supporting the hair’s natural keratin. It also lifts hair at the roots for an instantly thickening effect. It delivered noticeable results in just two weeks when it came to regrowth; testers said hair was left looking stronger and healthier, and they loved the herbal scent.
