I have thin,curly, damaged hair. Basically the worst. It’s hard for me to want to use heat protectant when it makes my hair look dirty or oily. I’ve been shopping around trying different things, and as of 2-3 weeks I’ve been using this product. So it looks thick and like omg your hair is gonna be greasy but surprisingly it’s not !! I put very little (dime size amount) in my palms and spread it through my wet clean hair a couple times. Might be easy to put too much so start off w little then repeat process as needed. Smell is nice, somewhat familiar. It helps my hair look less damaged, helps keep my hair straight, gives my hair some weight, and my hair is growing!! Like I def see some growth prob from being so well protected! Def worth a try. UPDATE. 6months later and I’m still using this. My hair has def grown and is being protected from heat !! Def will be buying another bottle soon. UPDATE 2/25/22 Been using this since 10/10/20. Works well with other products without feeling greasy ! So you go girl and take care of that hair ! Literally putting this and like 4 other products in my hair including oils/ serums. Hair is shiny and longer than ever. Who knew putting time and effort in your hair would make it healthier and just better lol. Some of us gotta work for some things right! Worth it. UPDATE 03/30/23 Still using this after every shower. I try new products regularly but this one is always my last step !! Review: Korean hair, fast drying, use a LITTLE! - I’m Korean and have long, thick, coarse hair, and it’s damaged from past dye-jobs. I also had a baby last year so a lot of hair got broken off midway or completely fell out... yay for postpartum hair-loss. I only use barely half a pea size of this oil to rub into my palms then apply to wet towel-dried hair (only on the bottom half of my hair, nowhere near the scalp or else I’ll just be a greaseball all day). Then I blow dry my hair as usual and I swear it really cuts down the drying time! And when you have long hair past halfway down your back you know how long it takes to dry all that. The scent is so minimal and after you’re done drying you don’t notice any scent anyway. When I didn’t use this before, even if I blow-dried my hair the same way it would take foreverrr and look so messy and clingy when done. But after drying with this oil in, my hair looks neat and smooth! Again, only use a TINY BIT. One time I accidentally used like two pea-sized globs and it INSTANTLY weighed down my whole hair and I looked so greasy! ## Features - Sleek Finish Essential - This concentrated thermal serum smooths hair texture, seals the cuticle, and eliminates frizz while enhancing shine for a polished, salon-quality finish across all hair types. - Cuticle-Sealing Technology - Designed to lock in moisture and smooth the hair surface, this formula helps reduce roughness and improve light reflection for visibly shinier, healthier-looking hair. - Lightweight Shine Boost - Delivers incredible shine without buildup or heaviness, making it ideal for daily styling routines where smoothness, movement, and softness are key. - Effortless Styling Control - Apply a small amount to damp or dry hair before heat styling to protect strands, reduce frizz, and create a sleek, controlled finish with lasting smoothness. - Trusted Professional Brand - Known for performance-driven styling solutions, RUSK delivers salon-quality results with innovative formulas designed to elevate everyday hair routines. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0017RD0KW | | ASIN | B0017RD0KW | | Best Sellers Rank | #34,227 in Beauty & Personal Care ( See Top 100 in Beauty & Personal Care ) #102 in Hair Styling Serums | | Brand Name | RUSK | | Customer Reviews | 4.5 4.5 out of 5 stars (2,195) | | Global Trade Identification Number | 00611186040669 | | Hair Type | Curly, Dry, Straight, Wavy, textured-hair | | Is Discontinued By Manufacturer | No | | Item Volume | 1 Fluid Ounces | | Item model number | IRATHERMS4A | | Liquid Volume | 4.2 Fluid Ounces | | Manufacturer | RUSK | | Manufacturer | RUSK | | Material Type Free | Alcohol Free | | Number of Items | 1 | | Product Benefits | Smooths frizz, seals cuticle, and delivers high-gloss shine with heat protection. | | Product Dimensions | 2 x 2 x 4.5 inches; 4.66 ounces | | Scent Name | Sulfate Free, Paraben Free, Alcohol Free & Vegan | | UPC | 611186040669 | | UPC | 611186040669 | | Unit Count | 125 Milliliters | ## Product Details - **Hair Type:** Curly, Dry, Straight, Wavy, textured-hair - **Liquid Volume:** 4.2 Fluid Ounces - **Material Type Free:** Alcohol Free - **Product Benefits:** Smooths frizz, seals cuticle, and delivers high-gloss shine with heat protection. - **Scent:** Sulfate Free, Paraben Free, Alcohol Free & Vegan ## Images ![Thermal Serum - Heat Protectant Treatment for Frizz Control - Smoothing with Added Shine, Moisture & Cuticle Sealing - Lightweight Anti-Humidity Hair Serum (4 oz) - Image 1](https://m.media-amazon.com/images/I/41M46aOIWfL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Possibly new favorite UPDATE *by C***Y on October 10, 2020* Ok so here goes.

This is great alone for a blowout, or used before gel for a scrunch and style curly look. I’ve tried many brands over 25 years and I keep coming back to this one. This and Str8 by the same brand are both fantastic products. ## Frequently Bought Together - Rusk Thermal Serum for Unisex 4.2 Oz Serum - Wired by Rusk for Unisex - 6 oz Crème IRAWRDP6 - Design Essentials Deep Moisture Milk Souffle For Dull, Dry & Thirsty Hair - Coconut & Monoi Collection - 12 Oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/13000165-thermal-serum-heat-protectant-treatment-for-frizz-control-smoothing-added](https://www.desertcart.vu/products/13000165-thermal-serum-heat-protectant-treatment-for-frizz-control-smoothing-added) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-09*
