Phyto doesn’t just use botanical extracts willy nilly—the brand picks and chooses parts of plants that have the highest concentration of active ingredients to reveal hair’s natural beauty.

Nice, but nothing special

I found this serum to do what it advertises: it does keep frizz down. However, I wouldn't say it does a better job than other similar products. Apparently the paraben-free nature of the product appeals to some, but other than that, there are a slew of other, less expensive options out there.

I've tried all kinds of products at all price points for my wavy hair. Phyto makes the only products that tame my hair without making it heavy or flat.

Non greasy formula that does not weigh you hair down. A dime size or less is needed for short hair.

This is my new favorite serum. It is light and doesn't mask over your hair. Perfect for finishing the look after a blow dry, curl or straighten! So happy this was in my box!

This is a perfect finishing oil. Never left month hair oily. Great to use on days that I use dry shampoo because it keeps my ends healthy and frizzy free.

Works nicely

I usually don't have a problem with frizz so I won't be purchasing this product but I did have the chance to try it on a day I was having some flyaways and frizz and it worked really well. Was lightweight and non greasy. Though I didn't care for the smell too much.

Loved the way this product made my hair feel. Just a small pump was enough to combat frizz and humidity all day while leaving a nice shine to my hair.

Enjoyed this product. Would probably buy. Left my hair feeling soft and smooth with a nice shine. I used it right out of the shower and it seems to work best that way
