hair transplantation Er:YAG laser CO2 laser standard punch techniques androgenetic alopecia hemostasis lateral thermal damage

TLDR The 5 W CO2 laser addition improved hemostasis without harming hair growth or causing damage.

This study compared hair transplantation techniques using Er:YAG laser, Er:YAG/CO2 laser at low (5 W) and high (10 W) power, and standard punch methods in 10 men with androgenetic alopecia. The results indicated that the addition of a 5 W CO2 laser to the Er:YAG laser improved hemostasis without significantly affecting mean hair counts or increasing lateral thermal damage. However, the high-power CO2 laser (10 W) led to slightly lower hair counts at 3 months and significantly lower counts at 6 months, along with increased lateral damage. Overall, the low-power CO2 addition was beneficial for hemostasis without adverse effects on hair growth or tissue damage.
