this is an amazing product for calming down the frizzies and I;m sure as the warm weather and humidity near I will be using it more. The key is to not use A little goes a long way and too much leaves my hair looking like I havent washed it in a week .TOO MUCH

I bought it on sale cuz it was Hella cheap at shoppers drug mart. It works alright, but I found if I didn't use it on the daily, it really didn't work as well

I got it as a sample along with her shampoo and conditioner. When you follow the steps it gives great results. However, I'm not a fan of products that only work when you apply heat, for eg blow drying or straightening, so I would only use it occasionally.

This Treemme Keratin Smooth Infusing serum is ok, but I have used better products. I found that it leaves your hair feeling like it is coated. It does smooth your hair, but it doesn't leave your hair feeling good.

I like this product but it must be used sparingly. I love the way it finished off my blow out, smoothing down any flyaway and broken hairs...it lasts a very long time and is reasonably priced.

This is a pretty okay product, I've bought it more than just once now. The trick to using it is to only use a VERY little amount, the tiniest bit or else it will give you a greasy kind of look. You want to wash your hair, blow dry/style and THEN apply it.

the tresemme line has siginificantly improved. The price can not be beat for the quality of hair care products.

The serum in combination with the hairspray, shampoo, and conditioner in the keratin smooth hair line leaves your hair feeling smooth for several days.

The serum, just a very small amount ( so does not over power your hair leaving it oily) leaves it smooth, no fly aways, relaxed, silky, beautiful. The smell is great, very mild but plesant, but the price!!

This serum is extremely effective if you have frizzy, stressed out hair. It smooths without being to heavy or greasy and doesn't have an overpowering scent. It is especially effective when used with all of the Keratin Smooth products in the Tresemme line.

I've started using this product and I really liked it for it doesn't make my hair feels oily and it tames all the frizz and static from my hair. And it has a great smell too! I always love Tresemme products!
