- Q
I have fine straight colored hair and I have terrible issues with static. I use Ultra conditioning Biolage shampoo and conditioner which is great and makes my hair shiny but it does not help with static! Does this shampoo and conditioner really help with static?
- Asked by Jen
- Official Answer By Matrix - Brand EngageHi there! We appreciate your interest in our Biolage products. Based on the information provided we recommend triying our Smooth Proof Leave-in Cream. Frizzy hair is prone to excess flyaways when exposed to static and humidity. Controls frizz and flyaways for smoother, more manageable hair. Static is controlled and hair is detangled with a hydrophobic shield. We hope you can give this a try and love it! https://tinyurl.com/yczqgr7aWas this answer helpful to you

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...

This conditioner is good but is expensive
Hair Type Straight Hair
I use it when my hair gets wavy, tangled or dry.
Horrible
With this price point, i thought for sure it would at least be decent. Almost the worst conditioner ove ever used. I brish my hair while conditioner is still in it wbcause my hair is super thick and curly. Its the only way i can manage. My hair rips right out with this. It doesnt smooth. It doesnt detangle. Dont waste your money.
Don't waste your money
Bought this because reviews seemed positive. But as a girly with thick and super frizzy hair this is an absolute NO! Left my hair with like a weird film on it and even after using it my hair felt super greasy like I hadn't even washed it. Do not waste your money on this.
Amazing
