I used to work in a hair salon that mainly sold retail products for over 5 years. I can tell you this product works! It is supposed to be applied directly to the scalp. It can dry out your hair if you apply it sloppily and get it all over your hair. The main thing you need is the shampoo and the follicle booster and scalp treatment liquid. If you find that the conditioner dries your hair too much, you can use a different one like Joico -K pak (which is the best hair care line ever!) or Biolage. IMO, K-pak is best because it strengthens your hair w/o weighing it down. I've brought many heads of hair "back to life" and witnessed customers hair grow. Most people whose hair falls out were not using it poperly and it didn't fall out, it broke off. If you are interested try to find someone at the store who is knowledgeable because sometime they have little girls working there that dont know what they are talking about which results in improper use, and your hair drying out. So basically get the Nioxin shampoo. Because for it to work your scalp has to be very clean. Get the follicle booster. A good conditioner. Not too oily. Joico K-pak is the best. (the reg condioner and the deep penetrating reconstructor) Also, Nioxin has a good leave in conditioner. I forgot the exact name, but it is the liquid leave-in weightless spray. Goodluck. Hope I helped. FYI: I've used it, customers have used it, my whole family including my granny while she was recovering from chemo, my boss and my friends have used it with great results... Also, I am an African American/Creole female. I've used it when my hair was natural and relaxed. I've used it on a wide variety of hair types including caucasian. I find that AA's have to use a stronger conditioner than the one provided by nioxin.
