Nioxin System 4 treatment<\/strong> (Scalp & Hair Treatment) is a leave-in treatment for the scalp and for coloured hair with noticeable thinning. It is the third step of the three-part Nioxin system, after the shampoo and conditioner. The 100 ml bottle has a handy pump.<\/p>\n

What is Nioxin System 4 treatment?<\/h2>\n

Nioxin specialises in care for thinning hair and groups its products into numbered systems. System 4 is designed for coloured hair that has clearly lost density. The treatment refreshes the scalp and boosts the volume of every strand, so your hair looks fuller and thicker. Nioxin says it delivers nutrients and antioxidants to the scalp and helps protect it against damage.<\/p>\n

\"Foamy<\/figure>\n

The formula includes caffeine, niacinamide, biotin, peppermint oil and menthol. UV filters help shield scalp and hair from the sun’s UV rays. The pack is marked Color Safe.<\/p>\n

Who it is for<\/h2>\n

System 4 suits coloured, dry or damaged hair with noticeable thinning. For light thinning on coloured hair Nioxin offers System 3, and for natural hair Systems 1 and 2. Find more products in our hair care<\/a> range.<\/p>\n

How to use<\/h2>\n
    \n
  1. Wash with the System 4 shampoo and apply the conditioner.<\/li>\n
  2. Towel-dry your hair.<\/li>\n
  3. Apply the treatment to the scalp, focusing on thinner areas.<\/li>\n
  4. Massage gently so it spreads evenly.<\/li>\n
  5. Leave it in, no rinsing needed, and style as usual.<\/li>\n<\/ol>\n

    Nioxin recommends using the complete system at least three times a week.<\/p>\n

    The final step of the system<\/h2>\n

    Each Nioxin system pairs a shampoo and a conditioner with a leave-in treatment. According to Nioxin, the treatment works best alongside the shampoo and conditioner of the same system. Explore the whole range on our Nioxin<\/a> page.<\/p>\n

    Frequently asked questions<\/h2>\n

    Should I rinse the treatment out?<\/h3>\n

    No. It stays on your scalp and hair. After applying it you can dry and style your hair as usual.<\/p>\n

    Does it protect hair from the sun?<\/h3>\n

    Yes. The formula contains UV filters that help protect scalp and hair from the sun’s UV rays.<\/p>\n
