What is the recommended dosage for Microneedling?

Hair Loss: 1.5 mm depth, weekly sessions

What are the side effects of Microneedling?

Potential side effects include: Scalp redness and inflammation (24-72 hours), Mild bleeding at treatment site, Scalp tenderness and soreness, Rare: infection if proper sterilization not maintained.

How does microneedling support hair regrowth?

Microneedling (dermarolling) creates controlled micro-injuries in the scalp, which may activate wound healing pathways and stimulate hair follicle stem cells. A landmark 2013 study in the International Journal of Trichology found that microneedling combined with minoxidil produced significantly greater hair regrowth than minoxidil alone. The controlled injury may enhance topical absorption and trigger growth factor release.

What needle depth is recommended for scalp microneedling?

Clinical studies on scalp microneedling typically use needle depths of 0.5 to 1.5 mm. A 2013 study used 1.5 mm needles weekly with positive results for androgenetic alopecia. Shallower depths (0.25-0.5 mm) may enhance topical product absorption with less discomfort, while deeper needling (1.0-1.5 mm) may provide stronger follicle stimulation. Professional guidance is recommended for deeper treatments.

How often should scalp microneedling be done for hair growth?

Clinical studies on scalp microneedling for androgenetic alopecia typically used sessions every 1 to 2 weeks, with most protocols running 12 to 24 weeks. Research across 52 studies with 8,451 participants supports weekly or biweekly sessions as effective. At-home rollers are often used weekly; professional dermaroller or microneedling pen treatments may be spaced further apart due to greater depth and recovery time.

Can microneedling enhance the effectiveness of minoxidil?

Yes — research suggests that microneedling may enhance minoxidil absorption and efficacy when used together. The micro-channels created by needling increase skin permeability and may trigger growth factor release (including VEGF and Wnt signaling pathway activation) that augments minoxidil's vascular effects. Several of the 52 studies with 8,451 participants tested the combination and found superior results compared to either treatment alone.

Does microneedling help with alopecia areata?

Research across 32 studies with 1,908 participants demonstrates Grade A (Strong) evidence for microneedling in alopecia areata. Scalp microneedling may help by disrupting the abnormal immune signaling around hair follicles and promoting local growth factor release. It is often used alongside topical corticosteroids or minoxidil in clinical practice, and combination approaches tend to show the strongest results in the literature.

About

Microneedling creates controlled micro-injuries in the scalp to activate wound healing cascades and release growth factors. Research suggests it may significantly enhance the effectiveness of topical minoxidil and has shown promising results as a standalone treatment in several RCTs.

How It Works

Controlled dermal injury activates wound healing cascade, releasing growth factors and increasing topical absorption.
