  • Finally, a product that makes a difference...
I have been buying anti frizz products for years. From creams to masks to serums and oils - I tried everything. And they were all disappointing. Until I got the smoothproof. I was told by my hairdresser that I should really give leave in creams another chance, but I was also advised to be patient and persistent. Smoothproof took very little of my patience to deliver amazing results. My hair is soft and revived now, on top of being smooth and frizz free. I just can't stop touching it. ... show more

  • The Frizzy Hair is GONE!
This product is absolutely wonderful!! I use it after each washing, just a little bit, then rub my hands together and put it through my hair - it smells so good too. Parts of my natural curl is frizzy after shampooing even with conditioner, but this stuff really works. I have already bought my second tube and will keep buying this as long as they sell it, I highly recommend it if you have curly hair that gets frizzy. ... show more

  • Non-greasy hair straightener!
Have been using for years! Never greasy but only apply the size of a pea rubbing in your hands. Keep in mind this product does not replace a flat iron straightener. This product tames and moisturizes. I have dyed hair past my shoulders and use nearly daily after my hair is dry after washing. Great product! Was cheaper on Amazon than going to salon to purchase! ... show more

  • Definitely worth the cost
I live in East TX, which is notorious for high humidity and heat. Every summer my hair gets frizzy and doesn’t stay straight. It’s 11:00 a.m. with humidity of 72% and I’ve been outside at work on and off since 7:30 (humidity was probably higher earlier) MY HAIR IS STILL STRAIGHT AND NO FRIZZ. This never happens. This is pricier than most creams but it is SO WORTH IT. ... show more

  • Great for frizzy, curly hair.
This stuff is wonderful! I use it along with Biolage Curly Hair Cleansing Conditioner (subs for shampoo and conditioner). The two together leave my hair curly, shiny and low frizz. Best hair products I've found in 64 years for curly hair that tends to frizz.

  • Excellent Product!
Excellent product! I usually don't use leave-in conditioners. But traveling through the desert with limited water available, I thought this would be a good time to try. Bought a different brand spray-on product first, which did not work well. Then ordered this one, and can honestly say that I'll stay with it forever.. Absorbs nicely into my long hair, leaving it detangled, smooth, and feeling nourished. Matrix Biolage products rock!! ... show more

  • Leaves my hair feeling soft, smooth, and frizz-free.
This is the best leave in conditioner for frizzy hair. I've always had straight hair but moving to Kentucky, the humidity has made my hair frizzy and static whenever I brush through it. This conditioner straightens my hair, takes away frizz and doesn't weigh my hair down. Highly recommend for anyone looking for a solution to frizzy hair. ... show more

  • I Think I Found The Answer!
My hair...terrible in damp and humid weather. Since I have used this product, my hair has not frizzed out even the tiniest bit. I have tried so many products - first one, even in the damp cold rain (mind you my hair is under an umbrella, the air itself would give me a layer of instant frizz. Not to mention what a hot, humid day would do to it.) No frizz what-so-ever! Just a pea size amount does the trick. Would definitely recommend :) ... show more
