Review: Treats hair kindly - Love this product Review: Very effective for thickening hair - My wife uses the complete nioxin system, as her hair grew back very thinly after some gruelling chemotherapy. The system works very well, with noticeable results. However, she seems to get through more of the conditioner, and this size represents very good value for money (rather than buying the whole system every time). ## Features - Conditioner: lightweight conditioner to improve hair resilience, hydrate scalp and hair from root to tip; hair treatments for dry damaged hair with progressed thinning - Biotin hair growth: infused with biotin, niacinamide and UV protecting ingredients; clinically designed to add thickness and fullness - Scalp treatment: gentle cleanser for scalp; removes impurities and follicle-clogging sebum for healthier hair growth environment - How to use: rub conditioner from root to ends, leave for 1-3 minutes; use alongside Scalp + Hair Shampoo and Scalp + Hair Thickening Treatment - Nioxin routine: for best results, use daily with Nioxin System 4 and preferred Nioxin hair styling products; add to your self care regimen or an optimal beauty gift ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D6WJNC8D | | Age Range Description | Adult | | Age range (description) | Adult | | Benefits | Advanced hair treatment for dry damaged hair - added thickness & fullness in 30 days for progressed thinning hair., Nourishes the scalp: infused with nourishing botanicals, antioxidants, and UV protecting ingredients, this kit's Scalp + Hair Thickening Treatment can nourish and revitalise the scalp, improving its overall health and condition., Reduces hair thinning: by strengthening hair resilienc… | | Best Sellers Rank | 931 in Beauty ( See Top 100 in Beauty ) 162 in Hair Conditioners | | Brand | NIOXIN | | Brand Name | NIOXIN | | Country Of Origin | USA | | Customer Reviews | 4.7 out of 5 stars 98 Reviews | | Hair Conditioner Type | Standard Hair Conditioner | | Hair Type | Aging, Color Treated, Damaged, Dry, Thin | | Hair type | Aging, Color Treated, Damaged, Dry, Thin | | Item Dimensions | 7.4 x 8.6 x 27.2 centimetres | | Item Form | Lotion | | Item Weight | 1000 Grams | | Item form | Lotion | | Liquid Volume | 1000 Millilitres | | Manufacturer | Wella Professionals | | Manufacturer Part Number | 4449 | | Material Features | Strengthening, protective | | Material feature | Strengthening, protective | | Model Number | 4449 | | Number of Items | 1 | | Package Type Name | Bottle | | Product benefits | Advanced hair treatment for dry damaged hair - added thickness & fullness in 30 days for progressed thinning hair., Nourishes the scalp: infused with nourishing botanicals, antioxidants, and UV protecting ingredients, this kit's Scalp + Hair Thickening Treatment can nourish and revitalise the scalp, improving its overall health and condition., Reduces hair thinning: by strengthening hair resilience, Nioxin System Kit 2 helps minimise hair breakage, promoting the appearance of fuller, thicker hair while protecting the hair color., Supports scalp health: the advanced formula of Nioxin System Kit 4 gently cleanses the scalp, removing impurities and excess sebum that can clog hair follicles, creating a healthier environment for the scalp., Thickens the hair: Nioxin System Kit 4 is clinically designed to add thickness and fullness to dry, damaged, color-treated hair with progressed thinning, with visible results in just 30 days.
