I had full coverage until about 48, then notice weak crown density then diffusion on top. Got on min and topical finasteride after ignoring it for 3 or 4 years. Seems to have stabilized nearly 2 years into the regime.@JuliusScissor
Your hair looks very dense. Mine is similar at 41. Was the thinning massively noticeable? I was hoping that post 40 I was out of the danger zone as I’m yet to see a man in real life, bald if they pass 40 with full coverage.
The treatments are serving you well!
