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

This is a great product and handy for travel. I used it in conjunction with the Toni & Guy shampoo and conditioner I got in a previous box.

I use this EVERY time I straighten my hair! It never causes it to get greasy like products have in the past and it smells great! Highly recommend!

I really liked the smell. It smelled like cinnamon and something else I couldnt put my finger on. It made my hair feel great and look great. I would buy it just for the smell though. They should make candles out of whatever the used in this.

AMAZING hair gloss!
SampledPurchased

I have wavy hair that can get super frizzy if not properly tamed. I've tried practically every hair gloss out there to finish my look after I blow dry and this one takes the cake! I absolutely love this polish. Its light and non-greasy yet really tames my fly-aways. HIGHLY RECOMMEND! You won't be sorry!

I received a sample of this in my monthly box and have really enjoyed using it. It made my hair shiny but not greasy and did not weigh my hair down either.

A little goes a long way!
Sampled

I've had this product for almost a year now and it's almost gone. Obviously I don't use it as often as most people do, but I use it about once or twice every 2 weeks when my hair gets crazy frizzy and it works like a charm. I don't use very much, I have shoulder length hair so just 1-2 pumps is enough to tame my frizz for the day. It doesn't weight my hair down either! Love this product.

Better than Argan oil
SampledPurchased

Prefer this to expensive argan oil but was disappointed when the full size was the same as the Birchbox sample. Good sample size, not so good for $15 full size. Will think twice before getting it again...

Serum is good, bottle leaks a lot!
Purchased

Overall, I really like this stuff. I got a sample in one of my Rent the Runway dresses and really enjoyed using it. The bottle started leaking on the sample I had which I assumed was due to traveling with it on an airplane so I threw out the sample and bought the "full size" which actually ended up being the exact same size as the sample. Anyway, besides assuming I'd be getting a larger bottle for what I was paying for this new bottle leaks just as bad as the first and it's never left my house. So now I will keep it until it runs out but definitely won't purchase again. I hate having to constantly clean up oil from my shelf and waste so much product. Sad face.

A little goes a long way!

I'm always excited to try a new frizz serum and while this one didn't totally disappoint, I think I'll stick with my John Freida. No matter how little serum I would run through my hair, it always seemed to make my hair feel a little greasy. It was also really hard to scrub off my hands. This product would work in a pinch but I don't think I'll be purchasing the full-size.
