Less hair fall
I'm very skeptical when it comes to products that claim to help with hair loss so I wasn't expecting this product to actually help, but it did within two weeks of usage. My hair was falling out in huge chunks due to high stress prior to switching to this system. Only problem is I don't see any baby ...

Good system but not seeing results
I have thick wavy/curly islander hair but I've noticed it thinning the past few years. I've used Nioxin for about 2 months now, the shampoo, conditioner, and the leave in treatment (System 4) and I honestly haven't seen any new growth... or thicker hair.

So far I really like this conditioner
Hair Type Straight Hair
I have below the shoulder, very fine straight with a little waviness to it. My hair is also a little frizzy if I don't blow dry it. I haven't used this conditioner but twice so, I don't really know how well it's going to work yet. I can tell you it's got a nice smell and not doesn't have an overly medicinal scent like some of the others I've used. It also leaves my hair soft and easy to brush out. I haven't used noticed that if I dont blow dry my hair and just let it air dry, it is more frizzier than usual. But overall I like this conditioner so far. I will try and update agin after I've used it awhile.
So far so good
Hair Type Straight Hair
I have very fine hair. It's mostly straight but does have a little waviness to it. It's also a little frizzy if I let it air dry. haven't used this shampoo but twice so far I really like it. The smell is nice and doesn't have the overwhelmingly medicinal scent a lot of others do. I have noticed if I don't dry my hair and let it air dry on its own it's a little more frizzier than normally. I will update after a couple of months use.
