Can you discuss microneedling for me?

Microneedling should have a needle length of 1.25mm and the highest number of needles, like Dr. Pen’s system, with 36 needles. Keep the microneedling in the same place for 10 seconds. Move from place to place until you covered the area. Do this once a week. The purpose of the depth and the frequency is to produce a healing cascade from the microneedling wounds. This stimulates the stem cells close to the scalp surface and along the upper part of the hair shaft. They are located between 1-1.5 mm from the scalp surface with a good population of stem cells just under the sebaceous gland of the hair shaft.

I have seen microneedling reverse what we often think is irreversible hair loss.  It is worth trying.
