Hair concealers: fibers, sprays and powders explained

How concealers work

All concealers do one of two things: they reduce the contrast between your scalp and your hair, or they add apparent bulk to the hair you have. Both work best where there's still some hair to cling to, so they're most effective on thinning areas, a widening part or a slightly receding hairline, and least effective on smooth bald skin.

The main types

Hair-building fibers

Fine, colored fibers, usually keratin or cotton based, carry a static charge and cling to existing hairs, making each one look thicker. They're shaken or sprayed over dry hair and often locked in with a light hairspray. They give the most natural fullness on diffuse thinning.

Colored sprays

Aerosol sprays tint the scalp and hair the same color, reducing see-through. They cover larger areas quickly but can look flat up close and may transfer onto pillows or hats.

Powders and root touch-ups

Pressed or loose powders are applied with a brush or puff along the part and hairline. They're precise and quick for small areas.

Concealer pens and creams

Pens and cream sticks fill in a soft hairline edge or temples by tinting the skin, good for small, defined areas.

Tips for a natural result

• Match the color slightly lighter than your hair; too dark looks painted.
• Apply to completely dry, styled hair.
• Build up in thin layers and check in daylight.
• Use a hairline template or comb to keep the front edge soft.
• Wash out every night so your scalp stays clean.

Limits

Heavy rain, swimming, intense sweating and wind can disturb most concealers, and they don't change the underlying hair loss. If your hair is still thinning, see a dermatologist about treatment, or read our guide to hair restoration options.
