Photobiostimulation Therapy (PBST) and Pulsed Electromagnetic Field Therapy (PEMF) in Hair Loss Treatment:...

Area of Science:

• Dermatology and Trichology
• Regenerative Medicine

Background:

• Hair loss (HL) treatments combining micro-needling, growth factors, and low-level light/laser therapy (photobiostimulation therapy - PBST) show promise but require standardization.
• Pulsed electromagnetic field therapy (PEMF) is explored as an adjunct to PBST for enhanced hair regrowth (HR-G).

Purpose of the Study:

• To compare the efficacy of combined PEMF and PBST versus PBST alone in treating androgenic alopecia (AGA) and COVID-19-related HL.
• To evaluate clinical and instrumental outcomes for hair regrowth.

Main Methods:

• A multicentric, retrospective, case-control study involving 40 patients (20 males, 20 females) with AGA or COVID-19-related HL.
• Patients were divided into two groups: study group (SG) received PEMF + PBST, and control group (CG) received PBST alone.
• Hair regrowth was assessed using photography, global assessment scales, and standardized phototrichograms over 16 weeks.

Main Results:

• The SG demonstrated a statistically significant increase in hair count (HC) of 14 hairs/0.65 cm² compared to baseline.
• The CG showed an HC increase of 11 hairs/0.65 cm².
• The combination of PEMF and PBST resulted in a statistically significant difference (p = 0.0325) in hair regrowth compared to PBST alone.

Conclusions:

• Combined PEMF and PBST is a more effective strategy for improving hair count in patients with hair loss than PBST monotherapy.
• This combination therapy shows potential for standardized and enhanced hair regrowth treatments.
