It’s true that, Diabetes causes hair loss. How does it does so is very simple: It causes poor blood circulation, due to which there’s a major effect on hair growth along with many other body functions.

Basically due to the poor blood circulation, the ability of hair follicles to operate normally get lower and lower. In normal circumstances, human hair grows for 2-6 years; then it goes into a period of dormancy, and eventually it dies and falls out as a new strand is produced in the follicle to push it out. Due to low poor blood circulation, the follicle doesn’t produce a new strand as normal, the old strand dies and falls out, and there is no replacement for it.

Also, the strands tend to die and fall out more quickly when blood circulation is poor, so more hair fall is obvious, with no chances of replacement.
