Most laser caps are overpriced, underpowered, or wrong for your stage of hair loss. After testing them all with real patients — one brand consistently came out on top.

Why GrowLuma Stands Out

"The most common mistake I see is men buying the wrong solution for their stage of hair loss. GrowLuma is the only brand that addresses this directly."

1. Three caps matched to your stage. 120 diodes for early shedding. 210 for moderate thinning. 258 for advanced cases. No other brand does this.
