Right balance of moisture
[I received this product in exchange for my honest review] I've been using the full system for about 6 weeks now and dont see dramatic results but have felt more confident with the thickness of my hair. I usually only wash my hair once or twice a week so even though I've been using it for 6 weeks ...

Not Very Effective
[I received this product in exchange for my honest review] I have used Redken products in the past and had a favorable experience, so I was very excited to try this. I don't typically use conditioners since I have a pixie cut and somewhat oily scalp. I might use one once a month or so, more as a ma...

Worst Conditioner I've Ever Used
I don't normally write reviews, but I had to say something about this conditioner. It might be great for the scalp, I'm not sure. But it left my hair. Feeling like sandpaper. I will probably be throwing out most of the bottle.
Don't waste your money
Just had my hair trimmed. 1st thing she asked me was what shampoo I started using. this one and the conditioner. for 2 weeks. she showed me the back of my hair and I've never seen breakage in my hair like this. I did notice less hair in the shower after washing but apparently for the past 2 weeks its been breaking mid-strand. needless to say I have a Bob cut now. highly disappointed in the amount i spent and in 2 weeks the damage I've never had before.
Light Weight
[I received this product in exchange for my honest review] I feel like this conditioner was like the shampoo, very light weight. It didn't feel heavy on the scalp at all and a little bit went a lot longer of a way than my normal conditioner. My hair felt light and fluffy after drying.

Very subpar condition
Hair Type Straight Hair
[I received this product in exchange for my honest review] The smell is good, but other than that, there's nothing about it that I would recommend it didn't make my hair soft. It didn't do anything. It felt like a very generic conditioner.
Consistency is key
Hair Type Straight Hair
[I received this product in exchange for my honest review] This conditioner was lightweight yet thick enough to coat all of my fine hairs. I noticed some length to my hair after using this system for a full 4 weeks I was hoping for more body and volume I did not get much of that but I do see growth and small baby hairs forming as well. I have very fine hair and I noticed repairing the breakage I was doing from blow drying with this conditioner as well. I was also pleasantly surprised that a little goes a long way even with hair to the middle of my back. With continued use this product will have many benefits for my hair.
