I’ve been using this shampoo for three months now and notice my hair feels cleaner and looks fuller. The scent is mild and doesn’t leave my hair feeling dry. My hair has become more manageable and I feel like it’s growing stronger.

It’s a good match for my coloured hair. The formula doesn’t fade my colour and gently removes oil. I see a slight improvement in thickness after consistent use, though results take time.
