How to Care for Grey Hair: Texture, Yellowing, Sun and the Right Cut

What changes when hair turns grey

Grey and white hairs are strands that grow without melanin, the pigment that gives hair its colour. The loss of colour is the obvious change, but many men notice the texture changes too: the new hairs can feel coarser, stick up more, and resist lying flat on the part or at the crown.

Grey hair also tends to feel drier, partly because the scalp often makes less oil with age. Put together, that means grey hair tends to look frizzy or dull faster than your old colour did, and it rewards a slightly more careful routine.

Why grey hair turns yellow, and how to stop it

Grey and white hair has no pigment to hide stains, so anything that tints it shows. Hard water minerals, smoke, pollution, sun exposure, heavy styling products and even some dandruff shampoos can leave a brassy or yellow cast, most visible in bright daylight.

Purple shampoo corrects this by depositing a faint violet tint that cancels yellow, the same way opposite colours cancel on a colour wheel. Use it once a week or every second week instead of your regular shampoo, and leave it on for one to three minutes; longer can leave very white hair with a lilac tinge.

1. Wet your hair and squeeze out the excess water.
2. Apply purple shampoo through the grey areas and lather.
3. Leave it for one to three minutes, less for pure white hair.
4. Rinse well, then follow with your usual conditioner, because purple shampoos can be drying.
5. Increase or reduce frequency depending on how the colour looks after a week.

Protect grey hair from the sun

Sun is harder on grey hair than on dark hair. The American Academy of Dermatology notes that light-coloured hair, including grey, is more vulnerable to UV damage because it lacks melanin, and that sun breaks down hair proteins, leaving it dry, brittle and frizzy.

In practice that means a hat for long days outdoors, a leave-in product with UV protection if you spend weekends on the water or the golf course, and sunscreen on any thinning part of the scalp. Men whose grey comes with a thinning crown should put SPF 30 or higher on exposed scalp, or wear a wide-brimmed hat.

A moisture routine that keeps grey soft

Grey hair behaves best with gentle cleansing and generous conditioning. Harsh or clarifying shampoos used too often leave it wiry, and hot water and high blow-dryer heat make the texture rougher.

Choose a mild shampoo, use conditioner after every wash, and add a light leave-in or cream if your grey stands up at the crown. Our guides to choosing a shampoo and whether men need conditioner go into the details.

• Wash two or three times a week unless your scalp is oily.
• Condition every wash; a mask once a week if it feels wiry.
• Use matte or light-hold styling products; heavy, dark-tinted waxes can dull grey.
• Blow-dry on low heat, or let it air dry.

Cuts that make grey look intentional

Grey looks strongest when the cut is clean and the edges are sharp. Long, unstructured grey can read as tired; the same colour in a tidy taper fade or a short side part reads as distinguished, because the contrast between the light hair and a crisp outline looks deliberate.

Many men with salt-and-pepper hair find the sides grey first, and a taper that keeps the sides short evens out the patchwork of colours. If you want to keep length on top, a scissor cut that removes bulk stops wiry grey from puffing out. For style ideas by age and colour, see haircuts for grey hair.

Grey beards need the same care

Beard hair often greys earlier and more unevenly than the scalp, and it yellows faster because it sits close to food, coffee and smoke. A purple shampoo on the beard every week or two, rinsed thoroughly, brightens it; beard oil helps with the wiry texture.

Tidy lines matter even more on a grey beard, since stray light hairs show against the skin. Our page on the grey beard covers shapes and trimming.
