Carolyn Arnold –
I’ve used this product on my medium-length hair and noticed a significant reduction in frizz. The hair feels softer and more manageable after just one application. It doesn’t leave my hair dry or brittle, which I appreciated. The blonde tone is balanced and doesn’t turn too warm. I’d recommend it to anyone looking for a natural, non-toxic straightening option.
Joanne Ince –
The formula works well for my curly hair. After using it, my hair is smoother and less frizzy. I did have to leave it on for a bit longer than the recommended time to get the full effect. It’s a good alternative to chemical straighteners with fewer side effects.
