Rusk Thermal Serum for Unisex 4.2 Oz 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 amazon would sell it, thank god they do. Having to pay twice the price is worth it.

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!

Love this for my coarse dry hair.

Love this stuff been using for years always keeps frizz away and protects from over heating.

Me gusto mucho, me quita el frizz y me da mucho brillo al cabello aparte que lo protege del calor

J'utilise ce produit depuis des années c'est très efficace avant de se servir d'un séchoir ou d'un fer à lisser les cheveux sont super doux et brillant on peut mettre ce sérum le matin sur cheveux secs et procéder à son brushing et ça c'est vraiment très pratique je le recommande à 100%

I was spending a fortune on Moroccan Oil hair product as my hair is triple processed and I wanted it to look smooth and feel soft. Someone recommended this and I figured I would try it for the price instead of $50.00 for a bottle. This works just as well if not better. It is thick so I am not using as much as the other and I use from root to end. I do not wash my hair everyday because of the triple process and it is never greasy. My hair is super shiny and incredibly soft after blowdrying considering the process that has been done, and blow drying straight. No frizz at all! I highly recommend this.
