A Randomized Evaluator Blinded Study of Effect of Microneedling in Androgenetic Alopecia: A Pilot Study PMC
Table Of Content
Microneedling may be a promising hair loss treatment, particularly for androgenic alopecia, to add to any current treatment regimens for those who can afford it. One study in particular explored the potential benefits of microneedling when used with a topical corticosteroid to treat alopecia areata. Some evidence suggests microneedling, also called dermarolling, can also stimulate hair growth.
Do At-Home Dermarollers Work?
Your healthcare provider will work with you to develop a treatment plan that addresses your individual goals. Overall, the process of microneedling usually takes about 45 minutes to one hour. Microneedling varies in cost depending on how many sessions you do as well as the issue you are addressing. If you decide that microneedling is right for you, you can expect to pay between $200 and $800 per session. Also, people who are on blood thinners or who have hemophilia may bleed too much with microneedling and should avoid this procedure. 0.5mm is a good starting point for scalp microneedling at home when done carefully.
Optimal Procedure Sequence
Microneedling has emerged as a promising therapeutic option for addressing different types of alopecia, demonstrating its potential to stimulate hair growth and improve the condition of the scalp across various forms of hair loss. Its effectiveness has been particularly noteworthy in treating androgenetic alopecia, alopecia areata, and telogen effluvium. Science seems to answer the question “Can microneedling stimulate hair growth? Like building muscle, utilizing the remarkable healing powers of the human body to improve skin and hair is an exciting area of research, with microneedling growing ever more popular. With evidence pointing to its effectiveness, safety, minimal side effects, low invasiveness, and ability to pair with other treatments, it will be interesting to see how microneedling will play a role in treating hair loss in years to come.
Microneedling For Hair Loss: Should You Do It For Hair Growth?
And when it comes to preventing hair loss, a study shows that both microneedling alone and microinfusion with minoxidil have been shown to be effective in treating alopecia. As an adjunct therapy, Giorgio et al. suggested that the release of growth factors from MN may induce immunosuppressive actions that amplify the effects of substances such as 5-aminolevulinic acid [31]. Ragab et al. found that MN alongside topical PRP improved hair parameters similarly to PRP injections, and suggested that MN may also enhance transdermal delivery for AA [29]. This doesn’t mean that you need to keep microneedling over the long term, though. You can also switch back to an FDA-approved treatment after your sessions, or continue with your combination therapy. Long-term hair regrowth can be maintained even after microneedling treatments end.

What to Expect During a Microneedling Treatment
Some speculate that microneedling may provoke the release of factors that promote hair growth or perhaps directly stimulate hair growth as a result of the small injury caused. Microneedling first gained its reputation as a scar treatment during the 1990s. Since then, it’s been studied as a potential alternative or adjunctive treatment for androgenic alopecia and alopecia areata. Microneedling is a type of cosmetic treatment that addresses various effects of aging. It’s also nicknamed skin needling because of its effects on increasing collagen production in the skin. Alopecia areata is an autoimmune condition that is characterized by “round patches of hair loss on the scalp,” although it can occur elsewhere on the body, Agbai says.
You’ll Reduce Your Risk of Infection
Some patients report their scalps being more sensitive to the sun after microneedling. Ideally, you would wear a hat and put on sunscreen every day, especially after the procedure. Ideally, you would combine microneedling at home with drug administration (e.g., corticosteroids, minoxidil 5%). These effects are primarily the result of collagen and elastin deposition after certain metabolic pathways get stimulated.
Microneedling Might Be The Secret to Preventing (and Treating) Hair Loss
If you’re considering a microneedling treatment, you’ll be able to choose from a wide range of different devices. The most common ones are usually referred to as the dermaroller, dermapen, and derma-stamp. Although microneedling has the word ‘needle’ in it, the tiny needles used in this procedure are nothing like the ones used to draw blood or deliver anesthesia. Doctors around the world use microneedling when applying hair regrowth medications and serums (e.g., minoxidil, platelet-rich plasma, exosomes).
What is the optimal care for skin after microneedling?
It also can't restore hair growth if the hair follicle has been irreversibly destroyed by advanced scarring. The actual procedure time can vary based on the size of the treatment area, but it generally takes less than 10 minutes. After the scalp microneedling is completed, your healthcare provider may apply a topical balm to the area or perform an injection, depending on what the goal of the microneedling session is. Your dermatologist rolls a device with thin needles over your skin, creating tiny micro-injuries.
Microneedling for Hair Regrowth: Does It Really Work?
Those for microneedling are generally mild and disappear within a day or two and include redness, possible infection, swelling, flaking, and irritation (4). The best serum after dermaroller treatment is still up in the air since vitamins, medications, and even certain hair creams can all have their benefits. These newer microneedling devices are still under investigation, and evidence behind their efficacy is still lacking. It will be interesting to see how these novel devices are used for microneedling in the future. Similarly to dermarollers, the needle lengths of dermapens vary widely than you would find in a dermatologist’s office. Therefore, the effectiveness of an at-home pen can be less than you would get professionally.
Unfortunately, there still aren’t any studies exploring the effects of long-term microneedling on its own, so it’s not certain how effective or helpful this hair loss treatment might be. In one study, researchers found that microneedling combined with topical minoxidil (a medication used to treat hair loss) was more effective at promoting hair growth than minoxidil alone. Another study showed that microneedling improved hair density and thickness in people with androgenetic alopecia (a common form of hair loss). Several studies have shown that microneedling can help improve hair density and thickness in people experiencing hair loss. The micro-injuries caused by the needles stimulate the production of growth factors and cytokines, which in turn promote hair growth.
Forthcoming large, double-anonymized human studies should help to determine the safety, efficacy, and potential benefits of microneedling for hair loss as a monotherapy. Microneedling may be able to help with hair regrowth in people with hair loss disorders like alopecia. The treatment has been shown to reduce hair loss when used alongside a primary treatment, such as Rogaine (minoxidil) or other growth factor solutions. A review of 33 studies found that participants in every study noticed an improvement in the appearance of their acne scars after microneedling. The treatment decreased inflammatory markers and increased collagen, which sped up the skin's healing process, reducing the appearance of scars.
You may still try the latter version for less invasive (but more temporary) results. Microneedling is a professional procedure performed in a board certified doctor’s office. You may notice skin irritation and redness within the first few days of the procedure.
