However it is also VERY drying and resulted in exaggerating the frizzy ends of my hair. So swings and roundabouts. ## Frequently Bought Together - Nioxin System 4 - Hair Thickening System For Damaged Hair with Progressed Thinning - Biotin & Niacinamide - Shampoo, Conditioner, Serum - Nioxin 3D Intensive Diaboost 100 ml - Nioxin Night Density Rescue Serum - Overnight Hair Thickening Serum for Optimised Hair Growth - with Ginger & Caffeine (70ml) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/656422641-nioxin-system-4-hair-thickening-system-for-damaged-hair-progressed](https://www.desertcart.us/products/656422641-nioxin-system-4-hair-thickening-system-for-damaged-hair-progressed) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-15*
