Being a crossfit buff I realised that high testosterone and laser doesn't go well with each other. Laser will effectively slow down new growth and efficiently remove very thin hairs but any existing thick hairs will always grow back. Electrolysis might be better but I haven't tried. I tried laser and been going for sessions almost 6 months with only 10% reduction.
I tried epilation which is not as painful as waxing and I got the same bump issues. I find that cinnamon scrubs work better than plastic exfoliators as the active ingredient actually helps to unclog pores. Clogged up pores are the reasons why ingrown hair happens, and most exfoliators only take out the top layer of dead skin.
