TLDR Non-laser devices show promise in treating hair issues, but more research is needed.

The review discusses significant advancements in non-laser energy-based devices for treating hair-related conditions, such as androgenetic alopecia and chemotherapy-induced alopecia. Techniques like iontophoresis, electrotrichogenesis, intense pulsed light (IPL), and radiofrequency (RF) show promise in enhancing drug delivery, stimulating hair growth, and reducing unwanted hair. Scalp cooling, particularly effective in preventing chemotherapy-induced alopecia, has shown success rates of 50-70% in studies with up to 1,411 patients. RF technology is noted for its potential in both hair removal and growth, while IPL demonstrates significant hair reduction. The review emphasizes the need for further research to refine these techniques and establish their long-term efficacy, highlighting the potential for personalized approaches in trichology.

research Seventy-MHz Ultrasound Detection of Early Signs Linked to the Severity, Patterns of Keratin Fragmentation, and Mechanisms of Generation of Collections and Tunnels in Hidradenitis Suppurativa

41 citations , November 2019 in “Journal of Ultrasound in Medicine”

The study tested the use of 70-MHz ultrasound to detect early signs of hidradenitis suppurativa (HS) linked to disease severity. It involved a cross-sectional analysis of ultrasound images from 139 HS patients compared to a healthy control group. The study found significant abnormalities in hair follicles, such as curved shapes and protrusions into pseudocysts, and identified ultrasound signs like the "bridge sign" and "sword sign" that were linked to HS severity. Two patterns of keratin fragmentation, multifragment and cylindrical, were observed. These findings suggested that ultrasound could aid in early HS diagnosis, management, and treatment evaluation by identifying early signs and keratin fragmentation patterns associated with fluid collections and tunnels.
