The caffeine and niacinamide formula increases hair diameter, helping fine hair look thicker and fuller. It also strengthens the hair fibre against breakage to help maintain length. The leave-in treatment is suitable for coloured hair and daily use.
Fuller-looking hair starts with the visible thickness of each fibre. The caffeine and niacinamide formula helps increase hair diameter while strengthening against breakage. This is particularly useful for fine hair when you want thicker-looking strands, easier styling and better length retention.
If your hair is fine and your style lacks fullness, care can focus on each strand's diameter. NIOXIN Diaboost is a hair diameter treatment that combines a fuller appearance with protection against breakage. It is a leave-in hair serum for daily use.
Protection against breakage adds a daily care benefit to the immediate fuller appearance. Peppermint and field mint oils complement scalp care, while the leave-in format allows you to continue styling straight after application. The treatment is suitable for all hair types, including coloured hair.

Nioxin is a professional hair and scalp care brand specialising in fine and thinning hair. Eva Graham founded the brand in 1987, and its first products were introduced through salons. Her personal experience of hair loss inspired an approach that places scalp care at the centre of the routine.
Nioxin takes inspiration from skincare, combining thorough cleansing with targeted scalp care. Its range also includes conditioning products, protection against breakage and treatments for fuller-looking hair.
Nioxin is known for three-step care systems containing a shampoo, conditioner and leave-in scalp and hair treatment. The systems are selected according to hair type and the degree of thinning, making it easier to build a coordinated routine.
Selected formulas contain niacinamide, caffeine, biotin and peppermint oil. Ingredients and application methods vary between products. Check each product’s description and ingredient list, particularly when adding a new treatment to an existing care system.
System Kit 1 is designed for natural, untreated hair with light thinning, while System Kit 2 is intended for the same hair type with more advanced thinning. System Kit 3 is designed for colour-treated, dry or damaged hair with light thinning. System Kit 4 addresses these hair types with more advanced thinning.
The systems’ shampoos provide cleansing, followed by hair conditioners. A leave-in treatment completes the routine. When choosing a kit or individual products, check the system number and intended hair type.
Nioxin also offers serums and treatments for fuller-looking hair. Diaboost is designed to enhance the appearance of hair thickness and protect against breakage. Root Lifting Spray helps lift hair at the roots and create volume.
For more intensive care, the range includes hair masks. Nioxin Anti-Breakage Mask is formulated to strengthen hair and help reduce breakage. Choose additional products according to whether your priority is caring for the lengths, looking after the scalp or adding volume during styling.
Nioxin is suited to women and men seeking a structured routine for fine or thinning hair. The range includes options for natural, colour-treated, dry and damaged hair. Products can be selected for home use or with guidance from a salon professional.
Start with a system suited to your hair type and add supplementary products as needed. Care products and volumising styling products serve different purposes, so choose according to your desired cosmetic result and follow each product’s directions.
