TLDR Low level laser therapy may promote hair growth for patterned hair loss, but more research is needed.
The systematic review conducted by Omeed Memar, Benjamin Caughlin, and Hamid Djalilian examined the effectiveness of low level laser therapy (LLLT) for androgenic and female pattern hair loss. The review found that light in the red spectrum was effective in promoting hair growth, based on observations of paradoxical hypertrichosis during laser hair removal attempts. However, the authors concluded that larger case-controlled studies were necessary to substantiate these findings.
