Having *platinum* blonde hair (not naturally... colored), I tend to get very dry, brittle, damaged hair. I decided to purchase *TRESemme Keratin Smooth Infusing Serum* a few months back because it was on sale at the drugstore & I had a wedding reception to attend that evening. I ran home; washed, dried and straightened my hair (with a high heat flat iron) and applied the infusing serum. I was *OVER-THE-MOON* impressed (and excited) with how amazing this product was!! I can honestly say that this is, by far, the *BEST* serum I have ever used! (And, trust me- I have an entire drawer filled with bottles, jars and sprays of smoothing serums that just do NOT work.) I -HIGHLY-recommend this! Not only does it smooth out frizzy, damaged hair- it actually greatly aids in the repair of severely damaged hair- adding shine, luster and perfectly polished... & all of this without the greasy, heavy mess that MOST of these serums leave! Another added bonus to this product is that you can use it on dry hair (to just smooth out areas where you need it) or on wet hair to really repair damaged hair- as well as adding shine for a perfectly polished look. Since you only need such a small amount--- this serum will last months!!! I can honestly say that I will continue to use this serum... forever! TRESemme has hit it out of the park with this keratin infused serum! And at SUCH an *awesome* price!!! I highly recommend this! You will be forever HAPPY :) :) :)

A tiny amount is all you need, spread it throughout your hair, but avoid the roots. Wonderful results. My overprocessed dry hair really loved this serum. It soaked right in yet didn't leave my hair feeling oily or weighed down. Left it shiny and no frizzies. Will use again and again. Works really well if you are blowdrying.

I like this Tresemme product for controlling frizz in hair. It works really well and lasts all day. It's a nice smelling product, very light doesn't weigh your hair down or make it feel crunchy or greasy!

I love this product. It's lightweight and controls frizz and dryness and I absolutely think it's worth every penny. I highly recommend this product!!!

I bought this to control my little frizzies. The kind I was previously using was very expensive so I gave this one a try. It worked ok but definitely not as good as the higher end one. I don't think I would buy it again. For the record, my hair is long and medium texture.

I bought this product and tried it on my curly dry frizzy hair not only did it soften my hair it also took all the frizz away wade down my hair so that they weren't so frizzy I like this product I will buy it again

I love using the serum on my hair just before styling with blow dryer and straighter. My hair is soft all day! Also keeps my frizz to a minimum. Great product

Such a terrible idea to use on my fine hair. This product weighed it down so that it looked limp and oily. Definitely not a product for fine or thin hair.

I love Tresemme products, they always do an amazing job without being heavy, the smell is amazing as well. I just recently tried this product as I had bleached some of my hair and it was a little fried. This made it smooth and manageable again, will continue to use and purchase

I will start by saying all tresseme products are the best you will never go wrong with a product.
My daughter wears hair extensions religiously I bought kerarjn smooth infusing serjm by tresemme an she absolutely loves it. Only apply to the ends of your hair or it will look greasy and you don't need a lot. Great product
