My hair looks and feels amazing

This leave in serum has got to be one of the best that I have tried. I have reddish frizzy hair and this certainly tames my mane and keeps it looking so healthy!

I absolutely love this hair serum. I picked it up once I got back from vacation, my hair was super dry and frizzy and I found that in one use it made a difference in how my hair felt and looked. I've been using it for about a month or 2 now and my hair looks shiny again, it's less frizzy and it definitely doesn't feel dry anymore.

I have found my holy grail hair serum. This is amazing! I use two pumps and it is enough for my shoulder length, wavy hair. It smells really good too, but I love it because of how well it works. Usually my head is a frizzy mess within two hours of showering but not with this. My hair is still wavy but so much more defined and less messy looking. I will always make sure I have this is my collection.

I started using Tresemme Keratin smooth, controls frizz for 48 hours last summer. My hair is silky even on a humid day. price for product is more then fair. It smells amazing too!

This product is like magic.
I have purple hair, which requires a lot of bleaching to maintain my roots, so my hair should be dry, brittle and really damaged, but because of this serum is it soft, shiny and healthy!
I apply it liberally to my ends while my hair is still a little bit damp and make sure that it's well combed in. I also will apply it to my ends when my hair is dry if it needs a little extra life. It's a great price and that little bottle lasts a LONG time.

This stuff is super light and get rids of all the annoying frizzies i get after straightening my hair. Smells nice too and it's very light weight. I always use it right after washing my hair and also add a little bit after I'm done styling it. Great price and value!

Beautiful hydrating serum! I have naturally curly and very frizzy hair but I straighten it often. The serum really fights frizz and gives my hair a beautiful shine. Ive gone through so many bottles of this stuff!

J'aime tellement ce sérum. Il n'est pas cher du tout pour un résultat incroyable. Il rend les cheveux super doux et soyeux ayant vraiment l'air en santé. Je le recommande fortement!

Not a super expensive product but works well. I think it smells nice and it feels good in my hair. It helps to tame my ends but I find it doesn't prevent all over frizziness.

I have fine hair that frizzes up in the heat and humidity. TRESemmé Keratin Smooth Keratin Infusing Serum keeps my hair smooth and styled, even when on a rainy day. It is my go to smoothing serum!
