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...

I love the way Biolage SmoothProof Conditioner for Frizzy Hair leaves my hair feeling. I am able to tame the frizz and it makes for more manageable hair. I have long thick hair and I blow dry it often, this has made the process so much easier. The smell is wonderful as well! Just a little bit of the product goes a long way. I am able to use this daily without it leaving my hair greasy and weighing it down. I definitely will recommend this to all my friends and family.
Great Conditioner!

I was very impressed with this conditioner. Compared to alternatives, I feel like I can use less of this product and it works fantastically. So in turn, it last longer. I feel like this would work well with dry hair. Will be getting this again!

So, first, I have always loved Biolage products. They smell great and leave my heart feeling great as well. That said, I'm not sure how well this worked to keep my hair frizz free. The first week, after receiving this product, it was rainy out and my hair still got pretty frizzy. Same thing happened the following week when it was super foggy. My hair does feel softer than when I first received the product so it might just be that my hair is untamable. I can't seem to find a product that really controls my frizz. I was hoping the combination of Biolage Smooth Proof shampoo and conditioner would help but I'm not sure that it did.
only if you blow dry

I preface this with, I dislike blow drying my hair. I've spent a long time getting. y hair healthy and avoid coloring it or using a ton of heat on it. I live in the south so frizz will occur, it's a sad truth. so when I got this as a voxbox to try I was excited. until I tried it, hated it, and realized I'd have to blow dry my hair everytime I washed it. I just cant, my hair is nice & healthy now, also, I'm lazy. so if you blow dry it'll be great, if you air dry, you'll feel acute disappointment.
