The efficacy of these treatments varies, so new add-on treatments are continuously being researched. The main differences between these two microneedling devices are in their designs. Dermarollers simply roll over the skin’s surface with hundreds of tiny needles, while dermapens target smaller areas with greater control of depth.
Can Microneedling Cure Androgenic Alopecia?
For example, pressing too hard or using needles that are too long can cause scarring. Keep scrolling to learn how microneedling can boost collagen (and hair growth) in your scalp. Finally, 4 out of 22 clinical studies utilized split-scalp study designs to evaluate MN against or as an adjuvant to topicals and/or injectables.
Potential Side Effects
Over the past few years, there has been an ongoing discussion about the use of microneedling at home. This DIY procedure using dermarolling can help with androgenetic alopecia and induce hair regrowth. For years, scientists have known that inflicting micro-injuries to the scalp induces follicular neogenesis by stimulating the natural healing processes of the skin. Microneedling is an aesthetic procedure that rejuvenates the skin by promoting collagen production. It involves using a skin roller equipped with small needles to create tiny punctures in the skin.

"Essentially, they're the ones getting ready to be lost permanently, [but] we can turn that around and make it a fuller, stronger, thicker hair." While it’s tempting to buy your own dermaroller, it’s much safer to leave these devices in the hands of a licensed and experienced professional for your hair loss treatment. Dermatologists strongly discourage doing microneedling at home or with providers who aren’t properly trained.

The best combination therapy using microneedling in the treatment of alopecia is still being researched. How often microneedling for hair should be done, for how long, and which additions will be key aspects of choosing treatment. And despite the promising results from the previously mentioned study, dermapens might be a better choice compared to using a dermaroller on the hairline given their increased precision. Dermarollers come in a wide range of styles and needle lengths, but generally are less precise than professional-grade machines and are not typically as adjustable for different areas or skin types. Modest results are still possible, offering a more financially appealing alternative to potentially expensive in-office treatments. If you're considering microneedling to treat or prevent hair loss, you'll want to start out with a clean and healthy scalp.

Macro-photographs were taken at fixed focus, distance, and exposure by use of a specialized adapter attached to the camera [Figure 1]. These images were printed on A4 size Kodak matt-photography paper at baseline and at 12 weeks [Figure 2]. The visible clipped hair was marked with a black dot and these were counted by a blinded evaluator at baseline and at 12 weeks (the target area was once again clipped off at week 12).
Microneedling’s Effect on Hair Growth
Dermarolling at home is another addition to the list of “at-home anti-aging treatments” sweeping the market. The number and variations of dermarollers available for purchase are ever-growing. This can cause some confusion about which device is best and whether the one you decided on really works.
"These things are helpful to improve the existing hair on the head — make it fuller, make it thicker," she explains. A larger concern, particularly if you receive the treatment at a medical spa or a clinic that doesn't specialize in microneedling for hair, is permanent hair damage and loss, says Dr. Kinler. Providers who aren't trained in the procedure may increase the needle depth too much, which can cause damage to the hair bulb when it enters the scalp, she explains. "I have seen patients come in with superficial breakage of the hair shaft at the scalp, which obviously takes a while to regenerate," she says.
While the exact reason for this type of hair loss is unknown, it is generally understood that “the immune system mistakenly attacks hair follicles, leading to hair loss,” she adds. If you’re experiencing elevated levels of the hormone dihydrotestosterone (DHT), your body will respond by shrinking your hair follicles and reducing the length of the hair growth cycle, according to Cleveland Clinic. Your provider may ask you to stop using certain topical creams, including retinoids or lotions to prepare for your first treatment. You may also be given a prophylactic prescription for antiviral medication if microneedling to the face. Be sure to follow their instructions and ask any questions you have so that your procedure goes smoothly.
Collagen levels in the skin decline as we age, and new collagen can be produced when the skin is in repair mode. If you are set with a medication, but need a dermaroller, we have you covered there, too. Our titanium-needled Strut dermaroller is only $11.99 with a sturdy design and longer-needles for scalp penetration. If you are also interested in using a topical formulation in conjunction with microneedling our doctors can answer your questions and help find a good routine for you.
Goren et al. demonstrated that reduced sulfotransferase activity in hair follicles predicted topical minoxidil nonresponders [42]. More recently, Sharma et al. found that, over 21 days, once-weekly microneedling led to a median increase in sulfotransferase activity of 37.5% [8]. Microneedling (MN) is a minimally invasive procedure involving the induction of percutaneous wounds with 0.25–5.00 mm medical-grade needles. MN can be administered at-home or in-clinic, with devices ranging from needling stamps, manual rollers, and automated pens with or without fractional radiofrequency. Scalp microneedling for hair loss (alopecia) works by stimulating specialized hair follicle stem cells, which can trigger enhanced hair growth. All studies exploring the effectiveness of microneedling for hair regrowth use medical-grade devices.
Dermatologists may recommend microneedling with other treatments, such as topical serums, radiofrequency, or platelet-rich plasma. A dermatologist can explain additional treatment options and their estimated costs. Since microneedling is considered a cosmetic or aesthetic procedure, it’s usually not covered by insurance. In the rare event that a doctor deems the procedure medically necessary, it’s recommended that you check with your insurance provider before your appointment. Unfortunately, microneedling is not covered by medical insurance as it's considered a cosmetic procedure. For instance, if you have a documented case of AA that's negatively affecting your quality of life or a debilitating case of acne, you may consider opting for insurance to pay for the procedure.
Skin irritations, bruising, and peeling are also common, yet mild, side effects following microneedling, adds Joseph. Still, no matter the tool used in your treatment—stamps or rollers—microneedling is thought to be relatively safe, Joseph tells us. For example, someone with a V-shaped widow's peak would start by microneedling hairline recession on both sides of the "V," where there's still some hair, but it's thinning. A woman with female-pattern hair loss, marked by frontal hairline thinning, diffuse thinning over the head's crown, or increased part width, could treat these areas of thinning hair with microneedling. Managing expectations is key if you're considering trying microneedling for hair loss. Microneedling as a standalone treatment has yet to be shown to regrow enough hair to cover large bald spots if someone has advanced hair loss.
After you are done microneedling, you will want to apply a calming and soothing lotion all over the scalp. At this point, you can stop microneedling, or you can use the same technique to go over the scalp diagonally. But, if you want to try out microneedling yourself at home due to the ease or the cost savings, you should have a pretty good idea of how to do it safely and effectively before you begin. Results may vary based on the severity of the skin concern, its location, and the treatment plan used. Microneedling often requires touch-up treatments as part of a long-term maintenance plan. It is said to rejuvenate and plump the skin with minimal discomfort and downtime, and it can be adjusted to fit each person’s needs.
