Best EVER
I have used biolage off and on for years. The salon I went to used a different product so I switched. My hair became hard to manage, dry and dull. I recently went back to biolage and used the smoothproof for the first time. I could not be happier with my decision. My hair is soft, smooth and shiny a...

Not good for natural curls
I have naturally curly, and fine hair. This shampoo and conditioner did not smooth the frizz at all. It made my hair poofy and dry. Also, this shampoo and conditioner set does not have a great smell at all. I used the line with the Smooth proof anti-frizz creme and the curl gel. Results were disapp...

Shrinkflation has destroyed Smooth Proof
I had been using the Smooth Proof combo since 2004. Year after year the execs water this down, which means I need to buy more for the same results because I'm putting 5x in my hair than what was originally required. All that with price increases too :/ The final blow for me has been that it doesnt even work anymore. I used to be able to wash my hair with the shampoo/conditioner in this line and my hair was good for 5 days. Now my hair barely lasts 2 days bo matter how much product I use. I have long, wavey and porous hair so if its not conditioned well, it becomes a fuzzy dredlock. Since I'm removing these shamp/cond combos from my rotation, I only have Paul Mitchell's Awapuhi to rely on.
I would definitely buy this again! Goodbye frizzy hair!

The staff at the Ulta store in Waverly are the nicest retail people I've ever encountered! They are always so friendly and helpful, it's the only Ulta location I will shop at! Thank you, Claudette for doing such a great job training your team!

Made my frizz worse and dried out my hair
Hair Type Wavy Hair
Cheap conditioner at an expensive price. This conditioner did absolutely nothing for my frizz. If anything, it made it worse and it made my scalp extremely itchy. I didn't like the smell either. I am unsure why people like this brand so much but I would definitely stay away.
This combo is a must!
Hair Type Very Curly Hair
The shampoo/conditioner combo is the only products I've found to make my hair feel like silk. This works extremely well in humid days! Ty!!!
