Needle size and frequency are the most important factors. If the needles are too small you don't stimulate a healing reaction or collagen growth. Too big needles and you just gash your scalp up and do tons of damage and bleed everywhere. My skull has a few lump spots so sometimes I'll see what looks like tiny droplets of blood, but I wouldn't say it's bleeding.
Doing it too often is bad too. Your skin needs to heal between treatments or else there's no point.
There's a balance that needs to be achieved.
Here's a guide that helped me build a schedual. Ideally you want to use the smallest needle that'll produce hair growth, as often as your skin can heal to 100%.

Every 4 -7 days I use 0.5mm roller.
Spray roller with rubbing alcohol to sterilize and let it dry.
Roll it 10 times in one direction, roll it 10 times in the perpendicular direction.
Spray with more alcohol to disinfect and put it away.

They say a 0.25mm needle is too small to stimulate hair growth, but helps asorbing topical treatments and can be safely used every day. I'm thinking about getting one to use in conjunction with Rogaine, to help absorption.

On the contrary, the larger needles are used to reduce scar tissue. But as mentioned above, larger needles produce blood and require more rest.

The whole process works the exact same way as the vampire facelift. In fact micro needling is a main part of that procedure, but they add a growth factor rich solution that's extracted from your own blood. I believe this solution is unnecessary or vastly overrated at the very least. If you ask me the "blood derived serum" is just a marketing gimmick to rip money off of rich people.
