We are Nioxin, the #1 professional hair care brand for thicker, fuller hair.
We create scientifically proven products to care for your scalp and make your hair look and feel thicker and fuller. We want everyone to be able to enjoy hair like this. Nioxin Professionals System 4 Kit is designed for color treated and damaged hair with advanced thinning, clinically and dermatologically tested.
Nioxin System 4 Densifying Treatment delivers essential nutrients, antioxidants and botanical extracts to the scalp to nourish and protect it. It refreshes the scalp and increases the volume of hair fibers, making hair look fuller and thicker. It also includes UV protection to protect the scalp and hair from sun damage.
To use, apply Nioxin System 4 Densifying Treatment Serum to damp, towel-dried hair, focusing on the scalp and problem areas. Gently massage to distribute evenly – no need to rinse. Then style as usual.
For best results, use the hair serum with Nioxin Professionals System 4 Shampoo and Conditioner. You can incorporate it into your personal care routine and combine it with other Nioxin styling products such as mousse, hair thickening gel or professional hairspray. It also makes a great beauty gift for someone who appreciates taking care of their hair.
