Alison Rees –
After using this shampoo for a week, my hair feels noticeably smoother, especially at the ends. The frizz is reduced and my curls hold better without looking dry. I love the shine it adds without weighing my hair down.
Steven Chapman –
My straight hair has never been this smooth. The coconut oil gives it a healthy glow and makes it easier to style. I’ve used it with the conditioner and the results are consistent.
Melanie Davidson –
It works well for frizz control, especially in humid weather. The hair feels hydrated, but I noticed it might be a bit heavy for very fine hair. Still, overall a great product.
Jane Berry –
I have chemically treated hair and this shampoo is gentle. It doesn’t strip color and keeps my hair soft and manageable every time I use it.
Madeleine Glover –
The smoothness is immediate after washing. I use it twice a week and my hair stays frizz-free throughout the day. A little pricey, but worth it for the results.
