Look for anything that adds fibers to the hair, pro hairstylistHaley Curnuttexplains.

Its the best bet to be sure that the hair itself will expand in size.

Thickening agents like silica silylate and starchy ingredients like maltodextrin or silk powder work particularly well.

We also considered our editors experiences with volumizers and texturizers and called on three expert hairstylists for their opinions.

We combined all these insights to curate this list of thickening products that deliver real results.

That’s where this strengthening oil from Mielle comes in.

It also hydrates every follicle, smooths split ends and stimulates the scalp.

Consider its TikTok virality justified.

It’s also infused with biotin to strengthen strands and provitamin B5 to increase smoothness and shine.

Star ingredients include strengthening keratin,hydratingchia seed oil,and texturizing copolymers.

It also adds shine and helps smooth the appearance of damage and split ends.

We love how it smells and that it’s light and gentle on fine hair types.

We just wish the spray mister worked a little better.

This one is amazing for anyone dealing with thinning hair but covets that bouncy, full look.

The fortifying formula strengthens the hair and balances the scalp by supporting its natural microbiome using probiotics.

It can feel a bit heavy on finer hair though, so we recommend potentiallydouble-shampooingto remove any excess product.

In addition to preventing split ends and breakage, this spray gets bonus points for being vegan and cruelty-free.

While we love the refreshing mint scent, it might be too intense for more sensitive scalps.

The volumizing features help lift roots, giving hair a fuller look and effectively masking thinner strands.

The styler contains silica-rich bamboo extract for instant volume and amino acid-packed rice extract to strengthen strands over time.

This one really does all the things.

It even works for those with alopecia.

Its super easy to use, doesnt get too sticky, and smells incredible too!

Its not typically recommended.

This is because shampooing cleanses the hair and often removes natural oils.

Instead, rinse your hair and use a thickening conditioner or other thickening product.
