Helps control static!
I have only used this shampoo three times. I wash my hair every 3 days. I like my hair straight. This product does help keep it smooth and static free. I'm still not sure how I feel about it. It leaves a greasy film on it and makes me want to wash my hair every day. My hair seems heavier.

NOT For Fine Hair
I really liked this shampoo. Polished my hair so the frizzies were kept at bay. Great for humid weather! The color looked great. Some volume was still there. Didn't irritate my eyes. Nice. EXCEPT for the wads of hair that would clog my drain when I washed it, the hairs that would fall out when I ble...

The Biolage shampoo and conditioner smooth made my hair so soft and shiny, and no frizz whatsoever. Love the smell as well. Will definitely be buying it again.

Didn't help much with smoothing. Made me break out.
my favorite shampoo
Hair Type Straight Hair
My hair is very thick and gets frizzy. This is the only shampoo I have found that smooths it out. Plus, I love the smell and the fact that it is an eco friendly brand!
The only shampoo that actually changed my hair.
Hair Type Very Curly Hair
After 10+ years of trying everything under the sun for my dry, frizzy, Type 3 curls, this Biolage Smooth Proof shampoo & conditioner combo is the only thing that's truly worked. I've dealt with years of bleaching, color damage, and products that made big promises but left my hair feeling like hay. This one? Soft. Nourished. Touchable. And it actually lasts between washes.It does take a couple weeks to see results—so if you've got textured hair, give it time. But once it kicked in, I was hooked. It's the only combo I'll use now. Bonus? I dye my hair red (aka the hardest color to keep alive), and this shampoo doesn't strip it—even when I use moderately warm water. That never happens.
Doesn't get hair clean
I love using similar smoothing shampoos and decided to try this one, but regret that decision. It doesn't get my hair clean and after a few days of using this shampoo my hair was left so oily that immediately after showering and blow drying my hair it looked like I haven't washed my hair in days. I washed my hair with a different brand's smoothing shampoo and my hair was clean again.

- Q
Is this sulfate free
- Asked by TT
- Official Answer By Biolage - Brand EngageWe appreciate your interest in our Smooth Proof Shampoo Frizzy Hair. This product does not claim to be sulfate-free. The purpose of adding sulfates in a shampoo formula is to create a richer lather and bubble when shampooing the hair. This shampoo uses color-safe sulfates so that it can be used to prolong the life of your hair color. We hope this information helps!Was this answer helpful to you
- Q
Is this similar to the discontinued Sugar Shine line? Will results be similar?
- Asked by Lisa
- Official Answer By Matrix - Brand EngageHi there! Great question! While both are fantastic formulas, they target different hair needs. Biolage Sugar Shine was designed to act as a "polisher" for normal-to-dull hair. It was a silicone-free, ultra-lightweight formula that focused on removing dulling impurities and styling buildup to reveal a high-gloss, glass-like shine. Biolage Smooth Proof is our ultimate "frizz tamer." It is a highly nourishing formula infused with cold-pressed camellia oil and glycerin. It works by creating a protective, humidity-resistant barrier around each hair strand to keep hair sleek, soft, and manageable in humid environments. If you loved the weightless, high-shine finish of Sugar Shine, you may find that the rich, oil-infused Smooth Proof formula feels heavier, especially if your hair is fine. However, if your main struggle is frizz, unruly texture, and static, Smooth Proof will give you excellent smoothing results! If you are trying to replicate the lightweight shine of the Sugar Shine line, we highly recommend trying Biolage ColorLast Shampoo. It is incredibly lightweight and excellent at smoothing the hair cuticle to maximize shine and radiance (even on non-color-treated hair).Was this answer helpful to you
