Kratom has absolutely accelerated my hair thinning. I started taking it maybe 3 or 4 years after my hair started to thin at a really, really, slow rate that made it almost unnoticeable unless you got in very close. And kratom still didn’t affect the rate of thinning at all until I started to take heavier doses more often. Then it was a real follicle fiesta.

So this is obviously just one anecdotal piece of subjective data, but I would think that light kratom use up to maybe 6, 8 grams a day won’t have too much of an effect on hair loss. It’s when you up the doses because of a rising tolerance that things can get messy. Tolerance breaks, people.
