Nioxin Brand Guide

Nioxin Brand Overview and History

Nioxin, a trailblazer in professional hair care, was founded in the late 1980s by hairstylist Kevin Wesson. Observing clients' struggles with thinning hair, he developed the first scalp therapy system to address hair loss at its source. Acquired by Procter & Gamble in 2000, Nioxin has grown into a global leader, now available in over 80 countries. The brand's philosophy centers on the scalp as the foundation of healthy hair, using a three-step system: cleanser shampoo, scalp therapy, and conditioner. With decades of research, Nioxin products are dermatologist-recommended and clinically proven to increase hair density by up to 11% in just 8 weeks. Today, Nioxin continues to innovate with advanced formulas incorporating antioxidants, peptides, and vitamins for all hair types experiencing thinning due to stress, aging, or environmental factors.

Nioxin excels in hair care categories focused on combating hair loss and enhancing thickness. Their lineup targets Beauty & Personal Care > Hair Care > Hair Loss Products and Shampoo & Conditioner > Shampoos.

  • Hair Loss Products: Comprehensive systems like the Scalp + Hair Thickening kits that include shampoos, conditioners, and treatments to purify the scalp, reduce breakage, and amplify volume.
  • Shampoos: Specialized formulas such as System 1 for natural or untreated hair with light thinning, and System 2 for progressed thinning on natural hair. Both feature niacinamide for scalp health and biotin for strand strength.
