## Description

Eliminate dryness and frizz instantly with Rusk Thermal Alcohol-free serum. It's a highly concentrated serum that smoothes and seals the hair's cuticle, eliminating dryness and frizziness instantly.

Review: Best straightening serum - 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 desertcart would sell it, thank god they do. Having to pay twice the price is worth it.
Review: Great protection - 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!
