I have bought multiple bottles of this! I have fine hair that I blow dry and straighten daily and I can't imagine NOT using this product. I pump it onto my hands, rub my hands together and smooth it from my mid shafts down to the ends. I find I have less frizz, less split ends and I feel confident that I won't burn my hair. My hair is protected. I really like this product and recommend it.

Best. Stuff ever if your working to achieve smooth straight hair this stuff really helps moisturize and keep frizzy at bay while letting you achieve smooth hair totally worth it

I'm not usually a fan of tresemme, but this product is affordable and works great. I have fine, curly hair and used this when I straightened it. It was glossy and smooth when using his product!

Hair dryers and straighteners are part of my regular hair routine which is so bad to use everyday. With TRESemme's Heat Activated Treatment I don't feel so bad to use heat on my hair because it helps my hair look less frizzy and brings out the shine in my hair that heat naturally takes away!

I bought this product on sale at Shoppers I really wanted to try, it is very good as a home treatment, but consider is not a professional keratin treatment, the results doesn't last too much, but is very good to tame your frizz and gives shine. I would buy it again for sure.

TRESemmé® Keratin Smooth System Heat Activated Treatment is fantastic! It really does protect hair from heat damage caused by blow dryers and straightning/curling irons. After showering, I towel dry my hair until damp and then massage a quarter-size dollop throughout my strands. My hair is a lot smoother after blow drying, that's for for sure!

I'm liking the TRESemme Keratin Smooth System Heat Activated Treatment so far. I use it after I shower on damp hair and then blow dry my hair. It gives me more volume which I'm very pleased with.

TRESemmé® Keratin Smooth System Heat Activated Treatment works amazing , I have long wavy hair and this stuff works great foe damage and frizz I recommend it.

Left my hair frizz free and helped straighten it really well. It didn't leave my hair feeling heavy like most smoothing products do. I buy this product all the time, great smoothing treatment.

J'utilise ce produit après avoir laver mes cheveux avec du shampoing et du revitalisant, juste avant de les sèché au sechoir! Ce produits ne les laisse pas seulement doux et soyeux, il protège contre les damages et la chaleur! Je le recommande!
