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

Silky, shiny hair!
Sampled

My hair can be quite blah. It's a mousy brown color and pretty fine. This product adds an instant silkiness and boost of shine that brightens up my boring tresses. However - a little bit goes a long way!

My hair is insanely frizzy from being pinned up for nursing school all the time but this serum makes it look so smooth and polished.

Great for shine, smoothness
Sampled

I was really excited to get this product in my box! I've been curious about trying out smoothing serums. For the most part, I like this, it does add a lot of shine, and it doesn't weigh hair down. BUT, I did find that it in the process of smoothing frizz and adding shine, it also sort of smoothed out my natural wave. Not a big deal, I'll reserve it for after a blowout or when I'm looking to sleek out because it really is great for that. :D

Perfect
Sampled

I had this sample for a while before finally trying it because I don't use hair serums very much. My hair is so thin and fine, and I'm fearful of anything making my hair look oily or greasy. This stuff did a perfect job of taming flyaways without making my hair look oily. And it smells phenomenal! Love it! Will definitely be ordering more!

Soft, shiny hair!
SampledPurchased

Just ordered the full size bottle. I think I can finally throw away all the other hair products I've bought. This is everything in one package. Helps my hair shine without any greasiness. No more flyaways. Works great with my straight iron. My hair is so soft. You only need a small amount, it goes a long way!

Light weight and great smelling!
SampledPurchased

i have been looking for a light weight finishing gloss for a while and this is the PERFECT product. i have fine hair, but a lot of it, and the Texas humidity definitely doesn't help. This provides just the right amount of sleekness without weighing my hair down - plus it smells awesome!
