Would you try a new, unproven hair restoration treatment for your own hair loss?

Induction Therapies and Collagen P.I.N. conducted a case series evaluating the effects of microneedling and plant-derived exosome serum on hair loss. Both participants in the small study reported reduced shedding and new hair growth after a three-month treatment protocol.

Why it matters

The findings suggest a potential non-invasive option for managing alopecia, though the small scale of the study means that further research is required to confirm the results. Researchers emphasize that larger controlled trials are necessary to validate the efficacy of this combined treatment approach.

The study included two 29-year-old patients who underwent three monthly treatments with microneedling at a 0.5 millimeter depth. Both participants applied the PRX8 Plant-Exo Stimulation Serum daily between sessions.

The players

Induction Therapies

Induction Therapies is a Louisville-based company focused on medical and cosmetic skin care solutions.

Collagen P.I.N.

Collagen P.I.N. is a manufacturer of medical-grade microneedling devices used in dermatology and aesthetic procedures.

The details

The treatment protocol required patients to use microneedling at a depth of 0.5 millimeters combined with daily application of a plant-derived exosome serum. After the three-month period, the male patient with androgenetic alopecia and the female patient with traction alopecia both observed positive results without reporting adverse events.

The clinical case series results were announced on October 21, 2026.

Culture Shift

This research reflects a growing interest in incorporating bio-derived serums into standard aesthetic procedures to enhance physical outcomes. It mirrors the broader shift toward integrating regenerative medicine components into routine dermatology and wellness practices.

Residents in Louisville looking for non-surgical hair loss options may find this research relevant, but should consult with a medical professional regarding the safety of such treatments. Patients should weigh the current limited evidence against traditional hair growth methods before making decisions.

The takeaway

While these initial findings are promising for those experiencing alopecia, the limited sample size means patients should treat the results as preliminary. Consult a dermatologist to discuss evidence-based treatments before starting any new hair growth regimen.
