Honest reviews from skincare lovers around the globe.
For amazingly smooth, tousled hair! Truest by S-Free Acid Heat TR Shampoo & Treatment Premium. This premium version of Truest by S-Free Acid Heat TR Shampoo & Treatment, which received an A rating from LDK the Beauty, boasts double the repair keratin for even more power. Its denser texture provides intensive repair for highly damaged hair. It leaves hair smooth and manageable, with a glossy finish. The gorgeous, translucent white freesia scent is perfect for my highly damaged hair. With continued use, the damage is less noticeable, and I'm now able to enjoy styling my hair in ways other than updos. The smooth finish is a delight, and the lovely white freesia scent makes bath time a truly enjoyable experience. The cute packaging is also exciting! @truest_by_sfree #truest #truest #acidheattreatment #touslysmoothhair #softandglossyfallwinterhairrecipes
I only use the treatment. First of all, I love the scent. After using a hair dryer, my hair is shiny and smooth, like I've just come back from the salon! The next day, the frizz and frizzy surface of my hair is much better than when I use other treatments lol. I love it so much that I keep using it, and recently I even bought the mini size for travel!
As the reviews said, it was neither good nor bad. I didn't feel like it had to be this way.
[Testing 200 Shampoos] No. 73 Thank you so much for always reading! Following me encourages me to keep posting ★ 20s Hair Type: Thick/Strong and bouncy, semi-long/Bleached hair (5 or 6 times) I really love the finish of this shampoo!! This shampoo is supposed to be a night fragrance that can be enjoyed by all genders, but...it has a calm night musk scent, which is quite distinctive. It's probably a matter of personal preference, but I'm okay with it. As for the finish, it's pretty average when I use it in the bath. It just lathers a little. However, when I dried my hair after the bath, I was amazed! My hair became so smooth, it was so straight I wanted to touch it forever!! I no longer have to worry about frizz. It doesn't even frizz at all! This is a shampoo I want more people to use!!
It was a bit rough when I washed it, but it became smooth. The scent seems to be a matter of personal preference.
