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

Alright

This product was okay. My hair generally has no frizz, and I already use a shine spray so I didn't notice a huge effect.

This made my hair have amazing shine and look so healthy (since I style it a lot) a little bit goes along way

Okay but I'm not a serum gal
Sampled

I'm not really someone who uses hair serums and this sample was okay. It felt a little greasy but did not weigh my hair down.

Smell okay
Sampled

This hair product smells okay but leaves a lot of residue on my hands. I expect some oil left behind in a product like this but it seems a bit much. I think there are better gloss serums on the market.

Fine line
Sampled

I have very fine hair, so often times trying to use any kind of shine/anti-frizz type product just bogs it down and makes it super limp. This product does none of that, which is awesome! I'll likely be ordering some for the summer when frizz becomes an issue again :)

I received this oil in my sample this month and really liked it. It's helps with fly aways and keeps hair healthy and shiny looking. I wouldn't purchase only because I have one brand that I consistently use and love more than any so far.

Not Suited for Oily Hair
Sampled

My hair gets greasy very fast and this product seemed to make things worse. Definitely would not recommend for those with oily hair types if you're planning on using it long-term. It did tame flyaways and made my hair much smoother in the short time I used it.

Pretty darn good
Sampled

it made my hair so soft and silky for real. I have course dry damaged hair from coloring it and I long for shiny silky hair again. I've used Aveda damage remedy, purology, and chi serum. This stuff by far worked way better because it is such a weightless serum that I didn't have to worry about looking too oily. I used one pump, rubbed it into my hands then ran my hands through my already dry and styled hair as if I were washing it. Now my hair is soft, supple, and smells great. It adds the shine that was missing and not at all greasy. It's worth a try for the $.
