## Customer Reviews

### ⭐⭐⭐⭐⭐ Best straightening serum
*by  on Reviewed in the United Kingdom 8 March 2014*

A really great product to use with hair straightener. Have never suffered from split ends using this product. Frizzy hair is soft and silky. Have been using it for a few years now, was unable to find it at my local hairdressing suppliers lately, never thought amazon would sell it, thank god they do. Having to pay twice the price is worth it.

### ⭐⭐⭐⭐ Great protection
*by  on Reviewed in the United Kingdom 8 October 2013*

I've used the thermal serum for several years, because it gives the best protection against using heat on your hair. Other products leave my hair feeling dry or don't actually protect it from the heat. Only the smell of the thermal serum good be a little more attractive (though it isn't a bad smell, just neutral). Rusk is a little more expensive, but definitely worth the money!

### ⭐⭐⭐⭐⭐ Nice
*by  on Reviewed in Canada 16 January 2026*

This is my 2nd bottle and I love this stuff!!
