Myth Or Maybe? - Colouring your hair makes it thicker?

FALSE There is no scientific evidence that colour molecules alone thicken hair as they are too small to make any difference. However, there are some colourant products which help improve the density of the hair, such as L'Oreal Professionnel Color Supreme. This anti-ageing hair colour creates truly natural-looking, multi-tonal results on white hair, while also helping to improve hair density.
