Pretty good

By Trailsofglitterandgravel

from Charleston sc

Comments about Mizani Thermasmooth Smooth Guard Anti-Frizz Serum:

I use this but it did not amaze me. Makes hair a little weighed down, so I recommend using VERY little and in damp hair only. It's slightly sticky and works really well to keep curls intact. I use it instead of hairspray when I curl my hair for a nice touchable hold, but when I want straight silken hair that has movement I use redken instant deflate instead!

    Comments about Mizani Thermasmooth Smooth Guard Anti-Frizz Serum:

    I am Caucasian, curl type III in the mizani curl classification. Overall my hair is very difficult to straighten as it is very frizzy and dry. This serum delivers, makes blow out easier and faster but it is very potent so you need to know how much of it your hair can handle before turning to greasy. Effective

      Best product for blow outs

      By Angel M

      from Jacksonville, FL

      Comments about Mizani Thermasmooth Smooth Guard Anti-Frizz Serum:

      this is the best product I've found to blow out my naturally curly hair. It gets my hair super straight, leaves it silky and shiny, protects from heat, humidity, frizz and reversion all while being a great heat protectant. I take a star away because every bottle I ever bought had a ineffective pump. I have hook a ton of my naturalista friends onto this product.
