The Best Hair Growth Serums to Save Your Thinning Strands

Best Hair Growth Serum for Fine Hair: Ro 3-in-1 Topical Finasteride Spray

Ro

3-in-1 Topical Finasteride Spray

Somehow the fine mist of this spray is super relaxing—and that’s partially because the brand has perfectly portioned each spritz to deliver the exact dose of the product you need. In addition to minoxidil, it contains tretinoin, which you might recognize from prescription retinol formulas. Because it helps to stimulate cell turnover, studies have shown that it purportedly makes it easier for the scalp to effectively absorb the minoxidil and finasteride. This entire bottle will last you for up to one month, and it’s recommended that you use it on a daily basis.

Best Hair Growth Serum with Minoxidil: Rogaine

Rogaine

5% Minoxidil Solution

This is probably the most recognizable brand for hair loss, and that’s because of the popularity of the brand’s oral medications. That said, the serum is incredibly cost-effective because each order comes with a six-month supply of serum-style dropper bottles.

It contains minoxidil, which works to stimulate follicle hair growth. While this is the only active ingredient, it has been clinically proven to be one of the most important. It also contains alcohol, which can be drying—especially if your scalp is experiencing any irritation.

Restoring Hair & Edge Drops

Beyoncé’s line of hair care products, Cécred, already had a huge following, and that was before someone online claimed that the brand’s hair drops basically helped him to regrow a full head of hair.

Best Hair Growth Serum for Sensitive Scalps: OneSkin OS-01 Scalp Serum

OneSkin

OS-01 Hair Peptide Scalp Serum

According to OneSkin, as you age, some cells enter a stage of senescence, thereby turning into senescent cells. These cells start to trigger premature aging, which can result in signs like thinning hair. This scalp serum is meant to prevent the accumulation of those senescent cells to encourage better, thicker hair growth, thereby reducing the appearance of aging—at least at the hair level. The serum does this by using a special peptide, as well as good-for-your-hair ingredients like the antioxidants fisetin, sunflower sprout extract, and rice bran water.

Best Hair Growth Serum for Damaged Hair: Vegamour GRO+ Advanced Hair Serum

Vegamour

GRO+ Advanced Hair Serum for Severe Signs of Thinning

While the price of this product can seem like a bit much, you only use a dropperful at a day so it will last longer than one month even if you use it daily as the brand recommends. This formula is not only intended to curb shedding, it’s also made with scalp hydration and hair density in mind. To help maintain a healthy scalp, Spanish microalgae serves as a prebiotic hydrator that will help build up the skin barrier. Finally, plant stem cells provide a protein-rich boost to the roots that help anchor and strengthen them.

Best Hair Growth Serum for Curly Hair: Briogeo Destined for Density

Briogeo

Destined for Density Peptide Hair Serum

Often, curly hair types tend to be drier because the hair strand is like a spiral staircase rather than a straight shoot for the oil to travel down. Because of this hair can break and this breakage can lead to it looking sparser than it should When that happens, you’ll want to stimulate the follicles to help hair grow. The formula also contains biotin, which naturally supports elasticity and strength while coating each strand to provide a thicker overall look. The copper peptides in the formula work to promote the production of collagen, which will definitely help the hair grow stronger over time. The caffeine and green coffee oil in the formula work hand-in-hand to stimulate the scalp, leaving each strand healthier overall.

While the biotin in this serum will help your hair look thicker, especially over time, this serum should be used more for the appearance of thicker hair versus actually promoting new growth. That said, peptides, which are included in this formula, have been found to improve hair re-growth as well in a number of studies.
