Steven Pullman –
Used this on my bleached hair after a heat session. It made my strands feel softer and more manageable. The shine returned quickly and my colour stayed vibrant for weeks. No greasiness or residue.
Melanie Clarkson –
My hair was dry and frizzy after a salon colour. After one application, it felt smoother and looked healthier. The shine is noticeable, especially in low light. A little goes a long way.
Dorothy Payne –
Great for maintaining colour integrity. My brunette hair stayed rich and deep after using this treatment. It doesn’t weigh hair down and works well even on fine strands.
Nicola Watson –
Applied it once a week to my blonde hair. Noticed a difference in texture and strength. Less breakage since using it. Would recommend to anyone with colour-treated hair.

After months of salon treatments and daily heat styling, my hair was weak and dull. This treatment restored moisture and gave me a natural shine. It’s become a weekly routine.
