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! ## Features - Eliminate dryness and frizz instantly - It's a highly concentrated serum that smoothest and seals the hair's cuticle - It is suitable for all hair types ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0017RD0KW | | Benefits | Conditioning, Frizz Control, Hydrating, Moisturizing, Nourishing, Smoothening, Strengthening | | Best Sellers Rank | 142,802 in Beauty ( See Top 100 in Beauty ) 478 in Hair Serums | | Brand Name | Rusk | | Customer Reviews | 4.5 out of 5 stars 2,054 Reviews | | Global Trade Identification Number | 00611186040669 | | Hair Type | All Hair Types,For,Frizz | | Hair type | All Hair Types,For,Frizz | | Item Form | Cream | | Item Type Name | Rusk Thermal Serum For Unisex 4.2 oz Serum | | Item Volume | 4 Fluid Ounces | | Item Weight | 0.14 Kilograms | | Item form | Cream | | Liquid Volume | 4 Fluid Ounces | | Liquid volume | 4 Fluid Ounces | | Manufacturer | Rusk | | Material Type Free | Alcohol Free | | Number of Items | 1 | | Product benefits | Conditioning, Frizz Control, Hydrating, Moisturizing, Nourishing, Smoothening, Strengthening | | Scent | Vanilla | | Scent Name | Vanilla | | UPC | 611186040669 | | Unit Count | 1 count | ## Product Details - **Product benefits:** Conditioning, Frizz Control, Hydrating, Moisturizing, Nourishing, Smoothening, Strengthening - **Hair type:** All Hair Types,For,Frizz - **Material Type Free:** Alcohol Free - **Scent:** Vanilla - **Liquid volume:** 4.2 Fluid Ounces - **Item form:** Serum - **Brand:** Rusk - **Number of items:** 1 - **Unit count:** 1 count - **Item volume:** 1 Fluid Ounces ## Images ![Rusk Thermal Serum for Unisex 4.2 Oz Serum - Image 1](https://m.media-amazon.com/images/I/41xrdfThkeL.jpg) ![Rusk Thermal Serum for Unisex 4.2 Oz Serum - Image 2](https://m.media-amazon.com/images/I/71a5YrXxSCL.jpg) ![Rusk Thermal Serum for Unisex 4.2 Oz Serum - Image 3](https://m.media-amazon.com/images/I/71zKhuJKo2L.jpg) ![Rusk Thermal Serum for Unisex 4.2 Oz Serum - Image 4](https://m.media-amazon.com/images/I/81I2-A5GurL.jpg) ![Rusk Thermal Serum for Unisex 4.2 Oz Serum - Image 5](https://m.media-amazon.com/images/I/61BiAw2RdKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best straightening serum *by C***L on 8 March 2014* A really great product to use with hair straightener.
