Non-ablative Er:YAG laser is an effective tool in the treatment arsenal of androgenetic alopecia.

The treatment was effective in treating AGA, confirmed by a decrease in AGA grade and by blinded evaluation of global photographs. Although the possible additive or complementary effect of topical minoxidil or nutraceuticals cannot be excluded, our results suggest that the non-ablative Er:YAG laser SMOOTH™ mode as a monotherapy, or in combination with PRP, is an efficient and safe treatment for AGA-with a high satisfaction rate among patients regardless of patient age, AGA duration, or AGA stage.
