For years, microneedling has been a not-so-secret weapon in cosmetic dermatology offices thanks to its ability to soften acne scars, fade hyperpigmentation, and smooth wrinkles. But the treatment’s appeal isn’t limited to the face alone. Derms say microneedling can also be surprisingly effective on the scalp, where it’s increasingly used as a relatively quick, low-downtime option for men hoping to slow hair loss and promote thicker, fuller growth.
Before you book an appointment to get pricked and prodded, check out the basics of microneedling and hair loss—including how it stacks up against more established solutions—below.
What is microneedling?
Microneedling is a minimally invasive procedure that uses tiny, surgical-grade needles to create microchannels in the skin or scalp to trigger the body’s natural wound-healing response. This process stimulates collagen and elastin production, helping to improve the skin’s tone and texture. Skin wins aside, microneedling also offers some compelling advantages for your hair.
“Microneedling drives the release of growth factors and increases blood flow, culminating in the activation of stem cells around the hair follicle,” says Dr. James Kilgour, MD, a board-certified dermatologist at Golden State Dermatology in Sacramento, California. “All of these signals work together to nudge dormant follicles back into a growth phase and strengthen the ones that are already active.” The micro-injuries also allow topical treatments—such as serums, platelet-rich plasma (PRP), and minoxidil—to penetrate more effectively. (For the uninitiated, PRP involves drawing blood and spinning it in a centrifuge to isolate platelets and growth factors before it’s topically applied or superficially injected. Tissue regeneration and healing, plus the growth of new blood vessels, are meant to produce thicker, healthier hair. Meanwhile, topical minoxidil is an FDA–approved medication that pushes hair into the growth phase of the hair-growth cycle and restores inactive hair follicles, says board-certified NYC cosmetic dermatologist Dr. Michele Green, MD.)
So what does the treatment entail? Most people sit with numbing cream on the treated area for up to 30 minutes. Once it’s smeared off, your provider passes the microneedling device over your skin or scalp. Topical solutions sometimes but not always follow before you’re out the door. Dr. Green says that you might experience minor redness, swelling, and pain, though side effects tend to be mild and short-lived.
How well does it work for hair loss?
To date, studies are limited on microneedling for hair loss on its own. (And in case your chin’s patchy, there’s a lack of research investigating microneedling specifically for beard growth.) Still, one 2022 review in the Journal of Cosmetic Dermatology found that microneedling significantly increased total hair count compared to 5% topical minoxidil—yet pairing the two together offered an even greater benefit.
According to Dr. Kilgour, microneedling truly shines as a synergistic therapy. “When paired with PRP, minoxidil, or other topical growth treatments, it amplifies results by enhancing absorption and stimulating follicular activity through multiple pathways,” he says. By targeting hair loss on multiple fronts, Dr. Kilgour says that (depending on your baseline) you can expect “modest to meaningful” improvements in fullness, shaft thickness, density, and overall hair health. Per Dr. Green, it’s also likely that you’ll shed less.
Both derms champion microneedling as an excellent option for men who want to maximize non-surgical outcomes—yet it’s neither a miracle worker nor a one-and-done solution.
“Microneedling can absolutely help slow hair loss, but it’s not a permanent switch that halts the underlying genetic process,” says Dr. Kilgour. Dr. Green adds that medical-grade hair loss therapies like oral Propecia are likely to be more effective. “However, scalp microneedling can work with other therapies—oral, topical, or in-office treatments—to prevent hair loss and promote hair regrowth,” she says.
In other words, consider microneedling to be a supporting player, rather than the sole MVP, in your hair restoration lineup.
Should you try it?
If you have androgenetic alopecia (A.K.A. male-pattern baldness) and are actively thinning or balding, microneedling is a treatment worth considering. Just note that you’ll need to commit to a series of treatments—with the standard being at least three, spaced a month apart—to achieve optimal outcomes. Each session will set you back at least a few hundred bucks, and adding PRP or other topicals could as much as double the price tag.
Sure, it’s an investment—but it’s one that can pay off when done consistently with an experienced provider.
“Microneedling is one of my favorite tools because it’s low-risk, minimally invasive, and genuinely effective, especially when incorporated into a comprehensive plan,” says Dr. Kilgour. It’s also worth doing sooner rather than later. “The earlier we address thinning, the more responsive the follicles are,” he says.
Rest assured that it can pack a punch no matter where you are in your hair restoration journey. “For men who are committed to a routine and want to optimize their results without jumping straight to medications or [surgical] procedures, microneedling is an excellent entry point,” says Dr. Kilgour. “And for those already on medical therapy, it can be the missing piece that takes their regrowth to the next level.”
