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!

The main reason why I decided to stick with this protectant was because I was impressed with the smell. It has a very light cucumber smell that disappears soon after applying. I really can't stand sweet, cocoa, vanilla, cupcake scents in hair products. I was so happy I found this product! The product works very well. I love the serum consistency. My hair has less breakage. Great product! That being said...I'm worried what the new signature scent will be be. I hope I don't have to go searching for another heat protectant.

Love this for my coarse dry hair.

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%

Works great for my hair. I read some comments about the smell. I actually like the smell, however it does go away once it's dry. Lightweight and doesn't leave my hair greasy. I have oily hair and I love this product!
