Scalp Microneedling for Hair Regrowth
How do Micro Injury Procedures like Microneedling or Microchanneling for Hair Regrowth work?
Scalp microneedling is an emerging therapeutic option for individuals experiencing hair thinning or androgenetic alopecia. This procedure involves controlled mechanical stimulation of the scalp using fine needles to induce micro-injuries in the dermis. These micro-injuries trigger a cascade of wound-healing responses, including increased expression of growth factors such as platelet-derived growth factor (PDGF), epidermal growth factor (EGF), and vascular endothelial growth factor (VEGF), all of which contribute to follicular stem cell activation and improved perifollicular angiogenesis. We offer micro injury procedures on their own, or with the use of hair growth stimulating peptides or human stem cell growth factors or exosomes.
How is Microchanneling different from Microneedling?
Microchanneling can offer a more comfortable alternative to scalp microneedling. Like microneedling, microchanneling hair growth treatments are formulated to nourish hair follicles back to a state of ideal health with select growth factor proteins that are naturally present in healthy, young hair follicles. This process allows for a normal hair growth cycle that leads to new hair growth and thicker, fuller-looking hair.
Both these treatments improves the overall condition of the scalp, rejuvenating damaged hair follicles and increasing circulation of nutrients for healthy hair. When delivered using microchanneling technology, the scalp experiences increased circulation and blood-flow to feed our follicles essential nutrients to promote increased hair growth.
Clinical Evidence Supporting Scalp Microneedling for Hair Regrowth
Recent clinical research has demonstrated promising outcomes when microneedling is used alone or in combination with established treatments such as topical minoxidil or platelet-rich plasma (PRP). A 2021 randomized controlled trial published in the International Journal of Trichology found that patients who underwent weekly microneedling in conjunction with 5% minoxidil showed significantly greater increases in hair count and patient satisfaction compared to those using minoxidil alone. Additionally, microneedling has been shown to enhance the transdermal absorption of topical therapies, thereby potentiating their efficacy. As a low-risk, minimally invasive modality, scalp microneedling offers a compelling adjunct or standalone option in the clinical management of hair loss.
Results from Scalp Microneedling Require Consistency
Results from scalp microneedling treatments typically begin to appear after 6-12 treatments, though this can vary based on individual factors such as the cause and extent of hair loss, age, overall health, and whether the treatment is combined with other therapies like exosomes, stem cells and/or minoxidil.
Here’s a general timeline:
Weeks 1–6: The scalp may feel tighter or more sensitive, and some shedding can occur as follicles shift phases.
Weeks 7–12: Subtle signs of improvement may begin, such as reduced shedding and a softer texture to newly emerging hair.
Weeks 13–18: Noticeable improvements in hair density, thickness, and regrowth are more common during this window.
Beyond 19+ weeks: Continued treatment can lead to further improvements, especially when done consistently over 6–12 months, and on-going maintenance.
Consistency is key. Most clinical studies showing meaningful results involved biweekly sessions for at least 4–8 months.
