Laser therapy and Platelet-Rich Plasma (PRP) are considered non-chemical therapies for hair loss that may be tried before systemic medications.

“so our non chemical therapies would be laser and or PRP and so a lot of times during a consultation process we're looking to try to institute something that's going to help someone's hair loss issue and they may say you know what I just don't want the risk of side effects of this drug I don't want to apply this medication into my body and I can certainly understand that they may want to try something that's non chemical whether it's a real or perceived value of less side effects laser has no side effects oh I see so you think of laser PRP topical as maybe something you would try even before you go systemic”
