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 2/25/22Been 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 03/30/23Still using this after every shower. I try new products regularly but this one is always my last step !!

Gorgeous!
This hair serum is the best that I have ever tried. It leaves my hair soft, shiny and full of life. I absolutely ❤️ it.

Absolutely LOVE
I’ve been using heatsmart dry oil serum for many years faithfully. They stopped making it and I’ve been trying to find something similar and thisproduct wins! A LITTLE GOES A LONG WAY. Just wanted people to know that. You don’t feel residue in your hair when it’s wet, it’s feels great while it’s blow drying (no stickiness), I have less frizz when I’m done (I use a paddle brush while drying) and mine and my daughter’s hair is shiny, but not oily when we’re done. I’m sold!

Gives hair lots of lift and body, but odd smell
It has a strange, funky odor. Thankfully, after hair is dried the smell goes away. Rusk is a brand I have known for years. This product gives lift and body. Also it will last a long time, as you only use a drop or two. Gives hair a smooth and silky feel.

Works great
I was a little hesitant to use this at first because of the heavy consistency, but I’m glad I did. My hair feels very smooth and is not sticky. It also helped calm down the frizzes.

makes my hair feel healthy even after a blow dry.
My hair is usually flat and after a blow dry just all over the place. I am so glad I tried this Thermal Serum. My hair feels conditioned and in control after the blow dry. I can style it easier because it is not all over the place. I don’t like my hair if I don’t use this. I love it, love it. I don’t say that about any other product I use consistently. If you haven’t tried it, you need to. My hair is color treated and fine so this is my go to product.

Just alright. Aveda makes a heat protector that is 100% better, but cost just a little more.
I imagined this protectant to be all smoothing, etc. It is somewhat, but not what I had hoped.

Don’t use too much!
This works very well, but definitely follow the instructions of a drop or two.

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.

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%

This is a great heat protector for your hair! Smells great, thick consistency so you only need a little bit! But very useful and makes your hair silky and shiny! Highly recommend!

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!
