A Deep Dive Into Best Hair Growth Serums

Everybody endures some degree of hair loss and shedding; on average, most women lose 100 to 150 hairs every day, according to Color Collective founder Kerry E. Yates.

This usually goes unnoticed, since hair ends up in your brush or on your bathroom floor, but if you see substantial clumps falling out when washing your hair, it might be a symptom of a larger problem. Similarly, abrupt and severe thinning of your strands — even if they aren’t shedding — might be alarming, but it’s also rather normal.

There are several causes of this sort of tress stress: According to Bridgette Hill, a trichologist and colorist at the Paul Labreque Salon in New York City, genetics, hormonal fluctuations, stress, sickness, certain prescription medications, hairstyling habits, and nutritional deficiencies are some of the primary reasons of female hair loss and shedding.

It’s a long list, to be sure, and Hill emphasizes that if you’re experiencing hair loss, you should always seek the opinion of your doctor.

Having said that, there are several hair growth serums and other leave-in treatments that can assist. Unlike wash-out shampoos, they penetrate the scalp and may do a variety of things depending on the recipe, adds Gretchen Friese, a trichologist at BosleyMD, a business that specializes in hair loss and restoration.

“They can enhance circulation, eliminate toxins and debris from the follicle, or even reawaken a dormant follicle so it can start producing hair again,” she explains.

Most people who have hair problems can benefit from one of these treatments, which can be applied all over or simply on certain places where you’re observing thinning, she says. (Side note: Ashley Graham swears by this scalp serum for strengthening her brittle baby hairs.)

The Most Effective Hair Growth Serums and Treatments

There are several hair growth serums to select from, each with its own unique set of components. Plant-based solutions, such as rosemary extract, CBD, and curcumin, are recommended by Hill for additional preventative measures and to help avoid thinning in the first place.

Keep in mind that just one chemical, minoxidil, is FDA-approved to really grow new hair, according to Howard Sobel, M.D., cosmetic dermatologist and director of Sobel Skin in New York City. (It’s the active component of Rogaine, which is available both over-the-counter and by prescription.)

Hill likes this mild serum, which boosts scalp circulation with a range of plant-based components (including lemon essential oil). Hill appreciates how simple this is to use, which is important because regular usage of any of these treatments is required for optimal outcomes. To that point, it must also be used only once a week for three months.

According to one Dermstore customer, “It’s quite simple to use. I use it on my scalp once a week after towel drying my hair. After that, I massage it in for a few minutes. Around week five or six, I observed new hairs sprouting in and my general hair growth speeding up. I’m really delighted with the outcome.”

“In four months, this serum can noticeably enhance hair density by up to 50% while lowering loss from combing and washing by up to 76%,” adds Friese.

This is due to a combination of ingredients not found in many other hair growth serums, including mung bean and red clover, which have been shown to help inhibit the production of dihydrotestosterone (DHT, a hormone involved in hair loss), and nicotiana benthamiana, an Australian plant whose proteins have been shown to increase the density of hair roots, she explains.

The Gro Hair Serum has quickly become a popular favorite for thinning hair and has gotten rave feedback from customers.

According to one Vegamour client, “This product significantly boosted my hair growth. I shed a lot due to stress, which helped me regenerate.”

Another person remarked, “Three months later, [my] bald patches are completely covered with baby hairs! The lotion is simple to use and does not leave a [greasy] residue, which is critical for me because I have oily hair.”
