Substances such as nicotine and caffeine are vasoconstrictors, in other words they narrow blood vessels causing less blood to flow to any particular area of the body. Ever noticed you cant get quite as hard when on a strong stimulant? Ever noticed how horny you get when high on weed? (a vasodilator).
I've noticed I bleed more dermarolling if my caffeine consumption is less. This would also explain why vaping/smoking is bad for hair loss as that too is a vasoconstrictor. If you're a chain smoker or a daily vaper, taper down and quit, it's doing absolutely nothing positive for your body
Something to keep in mind. Reduce caffeine and nicotine intake. Some foods can cause constriction or dilation too as well as medications. Any sort of opioid is a vasoconstrictor such as codeine.
Alcohol is another one. In low volumes it is a dilator, but if you're a chronic drinker it does the reverse, raising your blood pressure in the process.
