Nioxin Diaboost Thickening Xtrafusion Treatment (100ml) is designed to increase the thickness of your hair and give a fuller appearance. By targetting thinner hair strands which have decreasing diameters, this treatment uses breakthrough HTX Technology to increase the thickness of each and every individual hair strand.

Formulated with a blend of Niacinamide, Caffeine and Panthenol, Nioxin Diaboost is clinically proven to penetrate deep into the hair shaft to strengthen resilience and reduce hairloss.

Diaboost has a silky light-weight formulation aswell as an amazing fresh fragrance that is a dream to apply. The spray application makes this product extremely easy to use, and the non-sticky formula is ideal for all hair types. Overall, continued use of Diaboost will leave hair visibily thicker, healthier, fuller and with greater manageability.

Directions of use:

  • Spray directly onto your scalp and massage into your hair.
  • Use either in the morning or evening on wet or dry hair.
  • Can work in conjuction with your regular styling products.
  • Use 2-3 sprays on the hair daily.
