GREAT PRODUCT

About Me Product Junkie

Comments about Mizani Thermasmooth Smooth Guard Smoothing Serum:

This is the best product I have found for my stubborn naturally curly hair. I have tried them all and bought many based on high review ratings and all have failed. Trust me on this one especially curly haired girls. Forget trying to deal with humidity on an average day I would have to straighten at least the front and has left my hair dry and damaged and split ends galore. This product leaves it super shiny and tidy looking.
Everyone is different but don't get the less than 5 star reviews. This product is the best ever and plan on stocking up......these companies have a way of making certain products disappear, unfortunately.

      I have natural curly hair. This is the only product (and I've tried many) that kept my curls away. My hair remained straight for days without any touch ups from my flat iron.

        i am a naturalista and this product definitely make my hair straight. I'm not sure if there is less humidity or not but it does not frizz up as fast.

          This product is awesome! I struggled with my daughter's hair and this serum straighten her hair with little to no effort. We were both amazed at the results. A little expensive but a little goes a long way. We will continue to purchase.

              Comments about Mizani Thermasmooth Smooth Guard Smoothing Serum:

              I usually use about a nickel sized amount, and I actually pour it into my hand, rub them together, and lightly run my hands through my hair - either wet or dry. I have used it before blowdrying, before straightening, or after straightening to tame fly-aways and add a little shine.
              I have never had a problem with the weighed down, greasiness that others have. I don't put it directly on my roots either, about an inch or two below them.
              I love the shimmer it gives my hair!
              Its aimed for African hair styles, but I am white with platinum hair.

              Not for 'Mixed' Texture hair

                Comments about Mizani Thermasmooth Smooth Guard Smoothing Serum:

                My hair is naturally a very soft curl, not coarse but not texture free. I straighten it on a regular basis. I used this product on sections of my hair while straightening. It seemed to protect well. However, less than 2 hours after leaving my house for the evening, I had to put my hair up because it was out of control with frizz. Would not recommend to someone with 'mixed texture' hair.
