Grey hair causes: The science behind silver streaks

Why does hair turn grey? Peter explains, “hair colour is caused the presence of two types of melanin (a pigment) which is distributed throughout the hair structure. The variety of hair colours results from the quantity and ratio of the black-dark brown eumelanin and the reddish-brown pheomelanin. Without pigment hair is fairly translucent, which is how it appears grey or white.”

Hair follicles contain pigment cells that produce melanin, which is what gives your hair (and eyes and skin) its colour. When your body produces less of this pigment, the hair appears white, silver or grey.

As the hair turns grey for a variety of reasons, there is no one cause and as such, it’s not possible to stop your hair turning grey.

What products should I use on grey hair?

Now you know what causes hair to turn white, it’s important to learn how to maintain it. Like blondes, grey hair can throw off some golden or orange tones.

Manage these by using a purple shampoo that will neutralise the warmth, leaving you with icy silver locks. The Tigi Dumb Blonde Bed Head Purple Toning Shampoo, for example, uses violet toners to banish brassiness and brighten the hair.

If you’ve dyed your hair in an effort to cover up any grey roots, make sure to use a colour-enhancing shampoo like the TRESemmé Colour Revitalise Vibrance Protection Shampoo. This will gently cleanse and help keep your shade more vibrant, for longer.

What causes hair to go grey in your 20s?

Due to a variety of factors that impact why hair goes grey, due to genetics, you can also go grey earlier than expected.

“Melanin is produced at the bottom of the hair follicle in the scalp. Over time, the biological processes that produce melanin switch off, this is what causes hair to appear grey,” reveals Peter.

Generally, people go grey at different stages in their life, some much earlier than others.
