The Best Hair Serums for Every Hair Type

I get it, hair serums can be intimidating. Try a new one and you could wind up wasting your hair washing day on strands that are weighed down at the root, curls that you can’t quite coax out, or—perhaps worse of all—a style with a bad case of the blahs. Contrary to what your instincts might tell you, hair serums are for everyone. Whether you’re looking to stimulate hair growth postpartum, need a potion that will guard against heat damage in a major way, or have strands that are begging for a dose of nourishment, there’s a hair serum out there that’s up for the job. Oh, and if it’s shine you’re after, well, you’ve come to the right place because serums are like liquid gold for luster. While paying attention to the main objective of the formula is important, determining the best serum for your hair type and texture is equally so. If you have thin or fine hair, this becomes especially paramount as a product that’s not matched for your hair type can be the fastest way to a flat crown, and who wants that? Do your research before you take one of these best hair serums home but, once you find a winner, just know you two will be in it for the long haul.

A blend of botanical ingredients are called on to combat hair thinning and breakage, fortifying strands with lightweight hydration and antioxidant armor. After 90 days of using this clean formula daily, you could see thicker-looking and stronger-feeling hair. Apply directly to the scalp where you want to promote hair growth. Massage the formula into the scalp, then style as you would normally. Apply both morning and night for the best results. If you’re looking for even more hair-growth potential, Nutrafol recommends pairing this serum with one of their hair growth nutraceuticals.

When you’re using a straightening iron, the number one thing you should never do without is a good heat protectant.

Suitable for hair types ranging from straight to coily and hair textures from fine to thick, this serum works double duty to treat already-damaged hair and prevent future thermal damage. As the name implies, blue tansy flower oil is the key ingredient. It helps support new hair growth by nourishing follicles. Argan oil and grapeseed oil also come to play, moisturizing from scalp to ends while warding off frizz and protecting against split ends and breakage.

Best Serum for Thin Hair

Bumble and bumble Hairdresser’s Invisible Oil


If your thin or fine hair has convinced you that oils aren’t for you, let Bumble and bumble. Hairdresser’s Invisible Oil convince you otherwise. It’s light as air but a hands-down winner for reducing frizz, softening, adding shine, protecting against heat damaging, and even detangling. It’s a tall order for such a small bottle, but it gets the job done with just a couple drops per application.

Best Drugstore-Value Hair Serum

BioSilk Silk Therapy Original

You can call this one of the original strand-smoothing hair serums. The leave-in treatment helps prevent split ends and adds shine like nobody’s business. It should be applied from the scalp to the hair ends, but won’t weigh you down at the root thanks to a formula that’s as lightweight as it is effective. One Amazon reviewer shared, “This is a must-have product for blow-drying or hot pressing your hair. If you want it to be silky and not have a product that weighs it down, it’s this one! I’ve used other silk oils in the past and I always agree this one is the best. This is a very light oil and does the best with heat application (IE: hot irons, curling irons, blow dryers).”

Maize oil, argan oil, and procaxi oil provide a trifecta of strand-smoothing ingredients that nourish, soften, protect, and strengthen while providing undeniable shine. Use it before blow-drying as a styling aid or after for an extra boost of shine and frizz-fighting power.

Keeping curls and coils soft, hydrated, and smooth can be a tall order, but this treatment with argan oil at the helm is up for the challenge. Just a few drops worked evenly into either wet or dry hair is enough to start seeing the moisturizing, strengthening, elasticity-boosting benefits. Use it on its own or combine it with one or more of the equally effective products from the new (but already fan-favorite) product line formulated for natural hair.
