I love this hair activated product, it worked wonderfully when used prior to blow drying and I also used it before flat ironing and it left my hair protected, soft, and smooth overall!

I love this stuff, I am use my flat ironing on my hair regularly so I saw this product on the shelf and gave it a try. My hair was so nice and frizz free I am going to keep on using this as it is doing the job I need it to do. it smells good. does not make hair greasy either.

I love this stuff, I am constantly flat ironing my hair so I needed to get this.I like the pump too because you don't end up using too much. My hair was so nice and frizz free just like it claims to do. I don't think it lasted though after my was and condition. You have to keep using. Maybe over time I will see a difference. i am going to keep using to see how it helps. it smells good. does not make hair greasy either.

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!

TRESemmé Keratin Smooth System Heat Activated Treatment was an okay product that I recently tried out. I normally straight and blow dry my hair. And found that using too much of it didn't do much but make my hair very oily.
A little bit goes a long way with this product. But wasn't satisfied with results.

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 had such high hopes for this, but I was disappointed. It did smooth out my hair for a few hours after blow drying, but my frizz slowly crept in. It smelled great, didn't make my hair sticky but it just didn't keep me straight.

When I have an important meeting or outings I style my hair. And I'm worried about the damage. I thought I'd give it a chance and it did not live up to expectations. It didn't last long
