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 have never used a conditioner quite like this one. This conditioner is light yet hydrating. My hair is on the finer side and it does not weigh it down. I will definitely be repurchasing!
Good quality conditioner!

This conditioner is great. It coats my hair with just a very small amount so the bottle will lasts a very long time. The smell is great but not too strong. Its not as thick as some conditioners I have used in the past but it is very conditioning. It really does seem to help my hair be less frizzy. I have very fine and thin hair that is type 2C or 3A. I was able@to wear my hair curly for multiple days without it getting frizzy. I would definitely recommend this to others! I got this for free from Influenster in exchange for my honest review and I will continue to purchase this product because it is awesome!
So smooth!

I received this complimentary from Influenster in exchange for a review. I absolutely loved this! It made my hair very smooth, and I've had no issues with any frizz lately (which can sometimes be a problem for my fine textured hair). It smells great, is nice and light, and is a pleasure to use. Definitely not to heavy for my fine hair at all, but was still very conditioning. Would 100% recommend.

I truly enjoy this conditioner. I have never used a conditioner that leaves my hair so soft and manageable that I don't have to use a leave in conditioner once my hair is towel dried. I can brush it and let it go. The scent of it is so light, but so pleasing. If I could find a body wash or perfume in the same scent I would be in heaven. I even took this product and the shampoo on my trip to Arizona in travel bottles of course. I didn't want it confiscated at the airport, and it served me well in the hotels we stayed in on our drive back to Pennsylvania. I will be searching for sales for this before I run out.

If this product draws moisture to the hair, how is that combating frizz? Being out in humidity causes frizz.
