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...

I will be honest there are better smoothing products out there. The reason I tried this product is because I am in love with their hydra source shampoo. I will admit that this product did not fully smooth my hair but it smelled good and I finished the bottle because I do not believe in product waste.

I absolutely love how wonderful this shampoo is at helping to moisturize while smoothing unruly and frizzy locks. Has a luxurious lather and lovely scent. Hair is left soft and smooth with a gorgeous shine. I'm very satisfied with this. Also happy that it doesn't have coconut oil or natural proteins that can cause breakage.

- 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
