Nioxin products are hair-thinning treatment systems, each consisting of a cleanser, scalp therapy and scalp treatment designed for different types of hair and stages of hair loss, according the Nioxin website. There are reports of irritation to the scalp and allergic reactions in response to using the product, states Nioxin Reviews.
The Nioxin treatment systems help three out of four men and women in the United States by using advanced technologies to deliver thicker and fuller-looking hair, reports the official website.
As of February 2015, Nioxin has six different treatment systems, each consisting of a three-step process with a shampoo, conditioner and treatment formula, describes Nioxin Reviews. Choosing a system starts with determining the type of hair one has and matching it to one of two custom treatment systems specifically designed for the hair type. The benefits of the systems include thicker-looking hair, strengthening hair against future damage, reduction of overall hair loss and increase of hair texture. Results are typically seen after six months to one year of consistent use.
Potential side effects include temporary redness of the scalp due to increased blood flow, scalp irritation, flaking and hair loss, reports Nioxin Reviews. Additionally, there have been reports of allergic reactions, including swelling of the face and the onset of hives.
