The journey to healthy hair can be long and winding, especially because there are so many factors that influence the look and feel of your strands. Diet, vitamins, home remedies, and shampoo can all affect the thickness and quality of your hair, says Michelle Zive, PhD, RD, a registered dietitian for UC San Diego and coauthor of the National Academy of Sports Medicine Certified Nutrition Coach Program. Uncontrollable factors such as genetics, stress, certain conditions like trichotillomania, and hormone fluctuations due to childbirth and menopause can take their toll on hair, too, she explains. But that doesn’t mean you have to live with thinning strands. While you should certainly speak to your doctor about severe hair loss, there are over-the-counter hair-growth products that may help those with mild to moderate cases.
What is a hair-growth product?
Hair-growth products come in many forms, from topical serums, sprays, oils, to thickening shampoos and even oral supplements. Typically, one product is not a cure-all for hair loss. However, a consistent routine incorporating the right ingredients and practices can help.
What to consider and ingredients to look for in a hair-growth product
These contain growth-stimulating ingredients like topical minoxidil (the only FDA-approved treatment for hair loss, says Hadley King, MD, a dermatologist in New York City), as well as biotin, collagen, keratin, vitamin A, and more. And the best part: They’re suitable for all types of hair—straight, 4C curly, natural—you name it.

It’s expensive

It harnesses the power of LED light therapy to stimulate new hair growth, strengthen follicles, promote thickness, and extend the growth phase in the hair cycle.

Easy to apply
Cons
Need too apply twice daily for best results
This spray-on formula contains 2 percent minoxidil, which is clinically proven to promote faster hair growth in women, says Sonia Batra, MD, a board-certified dermatologist and cohost of The Doctors. The spray feature makes it more convenient than most formulas, too. Simply use the targeted nozzle to spray six pumps of product directly onto the scalp where you notice thinning hair. Apply it twice a day and within four months, you’ll start to notice a difference, per brand directions.

Clinically proven to regrow hair
Cons
Some buyers say the foam is messy to apply
Topical minoxidil—or Rogaine—is effective for both male and female hair loss, as well as hair loss due to chemotherapy, says Rina M. Allawh, MD, a board-certified dermatologist in Pennsylvania. The formula is available in both 2 percent and 5 percent topical solutions and 5 percent foam. Allawh recommends the 5 percent formulations for maximum efficacy. And don’t be turned off if you notice some initial shedding, she says. "Consistent use of Rogaine for months has been shown to have favorable results for both sexes. In fact, Rogaine works so well, I caution all my patients to avoid application on non-alopecic areas (like the face) to avoid unwanted hair growth."

Visibly improves thickness while also reducing feelings of stress because of the ashwaganda
Cons
It’s a lot of pills in one day
Nutrafol is one of the best supplements for hair growth, says Rita Linkner, MD, a board-certified dermatologist in New York City. It contains a variety of vitamins that are pro-hair growth, as well as saw palmetto, an herb that helps hair in the same fashion as propecia, a prescription medication for hair loss, she explains. It targets causes of thinning, including stress, lifestyle, and nutrition. You need to take four pills, once a daily for three to six months to begin seeing results.

Some buyers say it has a bad taste
According to experts, if you don’t get enough nutrition through diet alone (sometimes the case with vegans and vegetarians), an oral supplement may help stimulate hair growth. This formula is a dermatologist and patient favorite, says Jenny Sobera, MD, a board-certified dermatologist at Village Dermatology in Birmingham, Alabama. Take it twice daily for potentially thicker, healthier strands.

It’s a splurge
Light energy is used by doctors to stimulate and energize follicles on the scalp to regrow hair. It helps reverse thinning, increase density, and revitalize damaged hair strands. The process, known as photo-biostimulation, is similar to photosynthesis, and this at-home laser comb can help your hair with as little as a three months. For best results, use it three times a week for 11 minutes. Glide it over your scalp in slow combing motions, moving about a half inch every few seconds.
