so far it is kind of really bad, I have been using the nioxin #2 foam scalp treatment for thinning hair. After four days I could see a difference, my thinning hair looked thicker and I could feel small baby hairs growing, then after a week my scalp got very, very red, blotchy, swelling, scalp got very dry and flaky, the red blotchy spots spread to my forehead and it is causing my scalp and the area behind my ears to be very sore. I have stopped using it and bought the vitamin Biotin to help. I haven't used the nioxin in two days, the redness and swelling is slowing going away, my scalp and behind my ears are still sore. I used a old hair remedy for the dryness, I soaked my hair in extra virgin olive oil, leaving it in my hair and on my scalp for a couple of hours and it has helped with the dry and flaky scalp. Be careful of this product, if you are a person who is sensitive to products, chemicals and have skin allergies, I would think twice about using this product.
