I’ve used this conditioner for about two months after a full hair colour. My hair feels softer and has noticeably more body. The scalp feels less itchy, which was a big issue before. It’s a great match for my colour-treated hair.
Phil Mitchell –
The texture is light but effective. I notice my hair looks fuller after each use. It doesn’t weigh down my strands, which is important for me since I have fine hair.

After using this for a few weeks, my hair feels stronger and less prone to breakage. The soothing effect on my scalp is noticeable, especially after chemical treatments.

It works well for daily use, but I don’t see a dramatic change in volume right away. Still, it feels gentle and doesn’t leave residue.
