Another hair bummer: breakage. Protect strands before styling with TONI&GUY Prep Heat Protection Mist.

Silky Smooth

I tried this product on my wavy, sometimes fly away hair. The serum made it look so shiny and manageable. I event put it on when my hair was damp and gave me some nice, smooth waves.

Multi-Uses

I love this stuff! I only need to use just a little bit. I have very fine and very long hair and this just made my hair look shiny with no frizz issues. Having fine hair tends to tangle easy and it doesn't when I use this product. I also love this product because unlike a lot of shine products it doesn't make my hair look oily. On top of all this, I discovered that if I rub just a little bit on my hands before putting my hand lotion on it sealed my skin during the cold winter months and I didn't have any problems with dry painful cracks in my skin. I will be ordering this again to use with my lotion. I know that seems odd but its awesome! This was the first winter I didn't have to spend tons of money on thick goopy hand sealers.

Oily-looking hair

This made my hair look oily after I had just washed it. I have fine hair and this didn't do it any favors!

Still going strong

Love this serum! It is so perfect. It doesn't leave my hair oily and it doesn't take over the shake of my hair.

Really great!

This serum works sooo well. It helps keep my long, thin hair smooth during very long days at work. Keeps those pesky flyaways under control. Also, I hardly need to use any product at all, a little goes a very long time. I'm impressed!

This is awesome.

Seriously, it's flipping awesome. It makes my hair look and feel silky and smooth without making it look or feel greasy. It does not affect any volume to my hair either. I absolutely love this product.

Great for frizzies

I really like the Toni&Guy Shine Gloss serum! I put it in my purse if I was to go out and thought I might need a frizz fix! Smells pretty good and moisturizing too!
