ClinConnect Summary

This clinical trial is comparing two types of laser treatments to see which one is more effective for treating androgenetic alopecia, commonly known as male pattern baldness. The two lasers being tested are a non-ablative fractional 1565nm laser and an ablative 2940-nm fractional Er:YAG laser. Both types of lasers have shown promise in helping to regrow hair, but this is the first study to directly compare their effects.

To participate in this trial, you need to be a male between the ages of 18 and 65 who has been diagnosed with androgenetic alopecia, specifically at Norwood Hamilton stages II to V. You should not have had any laser treatments for hair loss in the past six months, and you must agree to share pictures and attend follow-up visits. It’s important to note that individuals with certain severe health conditions or skin issues near the treatment area may not be eligible. If you choose to take part in this study, you can expect to undergo one of the laser treatments and will be monitored to see how well your hair regrowth progresses.
