Microneedling for Hair Loss: How It Works and Why a Series of Treatments Matters

Hair loss is rarely caused by a single factor. Stress, hormones, immune system activity, circulation, and scalp health all play a role. Microneedling has become a supportive, non-surgical option because it works with the body’s own repair mechanisms rather than trying to force change. When offered as a series—most commonly six treatments spaced about one month apart—it allows the scalp time to respond gradually and sustainably.

Microneedling uses very fine, sterile needles to create tiny, controlled micro-injuries in the scalp. These micro-channels activate the body’s natural wound-healing response, increasing blood flow and delivering oxygen and nutrients to hair follicles. Growth factors are released, collagen production is stimulated, and the scalp tissue that supports hair growth becomes healthier and more resilient. Microneedling can also improve the absorption of topical treatments when they are used alongside the procedure.

Also, for many who have thinning eyebrows, I treat this area when I do the scalp if patients desire more hair growth in this area.

Why Six Monthly Treatments?

Hair grows in cycles, and the scalp needs time between sessions to heal and rebalance. Monthly treatments align with these natural rhythms while reducing the risk of irritation. Over the course of six treatments, changes are often gradual—such as reduced shedding, stronger strands, and improved scalp health—rather than immediate regrowth.

Microneedling and Alopecia Areata

Alopecia areata is an autoimmune condition in which the immune system creates antibodies that mistakenly attack hair follicles, leading to hair loss. The exact cause of this immune shift is not fully understood and is thought to involve a combination of genetic predisposition and environmental factors.

Microneedling does not treat the underlying autoimmune process itself. However, some people with alopecia areata may respond positively when microneedling is used thoughtfully. By improving local circulation, stimulating growth factors, and supporting healthier scalp tissue, microneedling may help create conditions where hair follicles can recover during periods when immune activity settles or fluctuates. Responses vary, and results cannot be guaranteed.

The Added Benefit of Light Therapy

For a more comprehensive approach, light therapy can be stacked with microneedling. Light therapy works by delivering specific wavelengths of light to the scalp that support cellular energy production, circulation, and tissue repair. When combined with microneedling, light therapy may enhance the overall impact by further supporting follicle function and calming the scalp environment.

Light therapy is now available as an add-on service to any microneedling or acupuncture treatment, allowing care to be tailored to individual needs. Stacking these therapies creates a layered approach that supports the scalp from multiple angles without adding stress to the body.

A Whole-Person Approach

Microneedling and light therapy are not cures, particularly when autoimmune factors are involved. They work best as part of a broader, compassionate approach that may include stress support, nervous system regulation, nutritional considerations, and appropriate medical care. The goal is not perfection, but supporting the body in doing what it can, at its own pace.

Gentle Medical Disclaimer

Microneedling is not intended to diagnose, treat, or cure medical conditions. Results vary from person to person, especially when autoimmune conditions such as alopecia areata are involved. Individuals with known autoimmune conditions should consult with their healthcare provider to determine whether microneedling is appropriate for their specific situation.

Should you be experiencing hair loss from cancer treatment, we will wait until your treatments are complete before introducing microneedling.

If you are experiencing hair loss from using a GLP-1 drug, microneedling may slow progression of hair loss. However, we would get the most out of the microneedling treatment once discontinuing use of the drugs.
