desertcart.com: RUSK Designer Collection Thermal Serum with Argan Oil, Alcohol-Free Conditioning Serum, Heat Protection and Shine, Frizz Eliminator, 4.2 oz : Beauty & Personal Care

Review: Possibly new favorite UPDATE - Ok so here goes. 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: Meet the last serum you will ever buy… - This is the best serum I’ve found for my fine curly and sometimes frizz prone hair. 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.

### ⭐⭐⭐⭐⭐ Scent goes away and hair feels soft
*by L***L on December 7, 2025*

I purchased this to use on my hair for flat ironing. When I got it I smelled it and I did not like the smell and I immediately requested to return. Well, I washed my hair and the other 2 heat protectants I got just make my hair feel like straw so I said well let me just try the Rusk serum. WOW I LOVE IT. My hair feels SO SOFT. I LOVE IT. The scent goes away after using it with the heat. I am so happy I decided to give it a try. I canceled my request to return it. THIS IS A KEEPER.
