## Description

Hair Building Fibres for Thinning Hair – Natural & Undetectable Hair Loss Concealer – Wind & Sweat Resistant – 27.5g (Black)

## Features

- INSTANTLY CONCEAL THINNING HAIR & BALD SPOTS: Hair Mass Hair Building Fibres deliver immediate results by binding to your natural hair to fill in thinning areas and bald patches. Perfect for men and women dealing with hair loss, thinning crowns, or receding hairlines. Look younger and more confident in seconds.
- STAYS PUT – WATER, WIND & SWEAT RESISTANT FORMULA: Our micro-cotton fibres are electrostatically charged to cling tightly to hair, resisting movement from sweat, rain, and wind. Enjoy all-day hold without smudging, running, or flaking — even during workouts or humid weather.
- COTTON-BASED FIBRES FOR A NATURAL, UNDETECTABLE FINISH: Unlike synthetic or keratin fibres, Hair Mass uses natural plant-derived cotton, creating a soft matte texture that mimics the look of real hair. No artificial shine or powdery residue — just fuller-looking hair that’s virtually impossible to detect.
- EASY TO APPLY & GENTLE ON SCALPS: Simply shake or spray the fibres onto clean, dry hair, then style as usual. The lightweight, non-irritating cotton formula is ideal for sensitive scalps and is suitable for daily use — including after transplants or dermatological treatments.
- LARGE 27.5G BOTTLE – UP TO 75 APPLICATIONS: Hair Mass offers outstanding value with a larger 27.5g bottle that lasts longer than most competitors. Available in multiple natural shades to suit your hair colour and blend flawlessly for a thick, full appearance.
