Try Hair Guru London hair fibres in a travel size 5g bottle. It is the easiest way to find your shade before you buy the full size. Our cotton fibres cover thinning hair and blend in with your own colour, so the result looks natural even close up. They hold through sweat, wind and rain, and wash out with ordinary shampoo. Available in 14 natural shades.

How to use: shake a small amount over dry, thinning areas and pat gently to blend, then style as normal. Washes out with shampoo. Made from natural cotton fibres. For external use only. Keep away from eyes. Store somewhere cool and dry. This is a hygiene product and cannot be returned once opened.
