4 Reasons You’ll Be Obsessed With Glass Hair Shine Serum
1. Frizz-Free Confidence
Say goodbye to flyaways—this serum smooths even the most stubborn strands while keeping your hair touchably soft and sleek.
2. Lightweight Shine
Adds that glossy, salon-worthy finish!
3. Clinically Backed Protection
Formulated with PhytoVie® Defense clinically tested for 450°F thermal protection, frizz-control and shine after first use.¹
4. Best For
This product was designed for frizzy and damaged hair types, but results can be experienced on the majority of hair types. For fine or oily hair types, start with a smaller amount.
I've been looking for something like this for a long time. I put a pea sized amount in my very thick hair and it came out shiny and very nearly frizz free, as in there were only 2 strands of hair frizz sticking out. (My hair does what it wants.) It really brought out the shine in my hair. It looked like it was made of light.

effective
This is a lightweight serum that kept my flyaway prone hair smooth and in control. I didn't notice any additional shine, but the smoothing was effective. Kept my hair smooth for 2 days between washings. Light and didn't weigh my hair down. Minimal scent so it doesn't clash with perfumes worn. I did use more than the recommended amount on one occasion and my hair looked greasy, so use sparingly.

Best Hair Serum!
This is the best hair serum I’ve ever tried! I have fine, chemically processed (lifted) hair and can never seem to get my hair feeling as great as the day you go to the salon, but thanks to this serum, I can get that feeling in between salon visits. A pea sized amount works perfectly for fine hair. If you have a thicker, more coiled hair structure, then a nickel sized amount may be more suitable. This is a product I definitely recommend.

Holy Grail!
The Frizz Control Shine Serum is my new HG finishing product. I live in super humid FL and have naturally wavy/frizzy hair so a finishing serum is a must. This one is simply amazing! It’s lightweight yet provides strong frizz control. Although the name indicates it increases shine, I didn’t really expect that result. But, it really did make my hair smooth AND shiny! Using the same shampoo/conditioner as usual and with the same styling-my hair was much nicer. Several friends even asked if I got a new keratin treatment! As a bonus, it smells like heaven. Highly recommend!

Perfect for fine hair!
This shine serum works instantly to tame frizz without being heavy or greasy. It did not make my hair look greasy on non-wash days which is a huge plus! I love the scent, it’s a clean vanilla that is almost identical to the discontinued Pacifica Vegan Silk line that I used to use. The ridges on the cap make it easier to grip when removing and look pretty as well. I would definitely recommend this to anyone looking to tame frizz and remain frizz-free even on humid days.

This product does its job way nicely, and I didn't notice any frizz. Hair was shiny and bouncy after the application. love the smell, during the humid and open air tend to break my hair , but not any more.

Great addition to hair routine
I enjoy this product- it smells great, a little strong at first, then it tones down. It is also a bit greasy upon application, but if you keep working it through, it settles in nicely. It helps tame my fly aways that enjoy sticking up!

A great serum!
I had the opportunity to try this serum and I really like it! It has a good texture that is actually better than my favorite serum. It's a great balance of thickness but thins out slightly when you rub it in your hands to apply. I love the scent and it really worked well for my dry, coarse hair. My hair requires some type of anti-frizz product at all times and this was the perfect everyday serum. My hair was very shiny and felt great! Thank you to Kitsch for gifting me this product to try out.

Lightweight and non-greasy!!
I usually have a lot of trouble with frizz and I was really excited to try out this product! Usually when I use a frizz control product I have to use a lot of product which then makes my hair look greasy, so I enjoyed not having that issue with this. I also found it really easy and convent to use as I usually used it before rushing out to work. Highly recommend!
