Best Hair Mask for Thin Hair

The best hair mask for thin hair is a light one that gives your lengths what they need without leaving your roots flat. Each fine strand is narrow, so it soaks up product fast and shows any extra weight. A mask made for thick, coarse hair will still condition fine hair. It just won't stop there, and by the next morning your hair sits flat and looks greasy.

Thin hair or thinning hair?

"Thin" can mean two things. Fine hair means each strand is narrow. Thinning hair means there are fewer strands on your head. This page is about fine hair. A mask works on the hair you have. It won't change how much grows.

Protein or moisture: pick by how your hair feels

Most masks lean one way or the other. Choose by what your hair is doing now, not by what the label promises.

• Protein masks suit fine hair that feels soft, limp and a bit stretchy when wet, or won't hold a curl or a blow-dry. Look for keratin, wheat protein or silk protein near the top of the ingredient list.
• Moisture masks suit fine hair that feels dry, rough or tangles easily, which is common if it's coloured or heat styled. Look for lighter hydrating ingredients like glycerin, aloe or panthenol.
• Too much protein shows up fast on fine hair. If it starts to feel stiff, straw-like or snaps when you brush it, switch to a moisture mask for a few weeks.

What to skip

Rich butters and heavy oils, like shea butter and coconut oil, usually go into masks made for thick, dry hair. On fine hair they tend to sit on top and weigh it down. If a mask is pitched at "very thick" or "coarse" hair, it isn't built for you, however good the reviews are.

How to use a mask on fine hair

• Shampoo first, then squeeze out as much water as you can so the mask isn't watered down.
• Apply from mid-lengths to ends only. Keep it off your scalp and roots.
• Start with less than you think you need. You can always add more.
• Leave it on for the time on the pack. Longer doesn't mean better on fine hair.
• Rinse well with lukewarm water until your hair stops feeling slippery.
• Once a week is plenty for most fine hair. If your hair is in good shape, once a fortnight is fine.

Mask, conditioner, or both?

On mask days, the mask takes the place of your conditioner. On other wash days, use a light conditioner for fine hair on your mid-lengths and ends. If you're still choosing a wash, start with the best shampoo for fine hair, then add the mask.

And if your fine hair isn't dry, damaged or coloured, you may not need a mask at all. A good conditioner might be all it takes.

When fine hair has another problem too

Fine hair is often coloured, dry or splitting at the ends as well. Pick the mask for the bigger problem, then use it with a light hand.

• If colour fades fast or feels rough after toning, compare the best hair mask for coloured hair.
• If the ends are the main issue, look at the best hair mask for split ends and keep it on the last few centimetres.
• If your hair feels dry from roots to tips, see our best hair mask for dry hair picks and use half the amount.
• If it puffs up in humid weather, a hair mask for frizzy hair can work, applied to the ends only.
