Colin Paige –
I’ve used this spray on my coloured and chemically treated hair for a few weeks now. It feels like my hair is more resilient and less prone to snapping. The detangling is excellent, especially after washing. I apply it before styling and notice a significant improvement in softness and strength.
Benjamin Short –
My hair has been weak and frizzy for a long time. After using this spray regularly, it feels smoother and more manageable. It doesn’t leave a greasy residue and works well with my daily routine. A good addition to my hair care regimen.
Faith Wilson –
I applied it after washing and before blow-drying. My hair stayed in place better and didn’t tangle as much. It’s especially helpful for my curly hair that tends to break easily. I’d recommend it to anyone with damaged or coloured hair.
