Microneedling has grown in popularity as a noninvasive way to treat a variety of skin concerns, from reducing scarring to treating fine lines and wrinkles. While there are several types of microneedling products, they all have a key feature—they contain many small, thin needles. As microneedling wounds heal, the skin is left smoother and brighter with reduced wrinkles.
Microneedling use has expanded into hair loss for its ability to stimulate the scalp and hair follicles directly, providing a targeted approach to hair restoration. Combining microneedling with PRP, oral or topical solutions can further enhance the results and promote hair growth.
How It Works
Rolling a microneedling handpiece outfitted with tiny needles across patchy areas on the scalp creates microscopic wounds, William Gaunitz, FWTS, certified trichologist and founder of Advanced Trichology, told New Beauty. The punctures in the upper dermis and into the dermal layer stimulate growth factors and tissue recovery, resulting in the body rebuilding the scalp and hair follicles.
By creating microchannels in the scalp, microneedling helps enhance the absorption of topical minoxidil, potentially increasing its efficacy. Additionally, the micro-injuries induced by the needles may trigger a wound-healing response, leading to increased blood flow and collagen production, according to an article from Real Simple.
The initial results likely won’t be seen for about six weeks. However, once new growth becomes evident, it is critical to continue with the treatments to achieve maximum results. Most patients require several treatments to achieve ideal results and then continue with maintenance treatments every three to 12 months.
Studies currently indicate that there are positive results when microneedling is used alongside topical or oral alopecia medications. When microneedling is utilized as an adjunct therapy for alopecia, results present an increase in hair density, thickness, and the quality of hair regrowth, Veronica Joseph, an IAT-certified hair practitioner, told Byrdie.
Microinfusion is another popular cosmetic procedure that uses tiny needles on the skin in order to achieve a healthy and radiant complexion. Microinfusion involves about 20 to 30 hollow needles that deliver nutrients directly into the dermis. This may lead to more immediate results and less downtime than microneedling, according to a 2016 study.
Scalp microneedling is generally well-tolerated, with most patients experiencing mild discomfort during the procedure. Topical numbing creams are often applied before the treatment to minimize any potential discomfort.
