Does microneedling really work?

I’m writing this because, I keep finding contrasting opinions about microneedling Since scientific papers have already proven the efficacy of this therapy, especially when combined with other treatments, my main questions are related to depth and frequency, Is the recommended depth of needles 1.5mm, 1mm, or even lower than that? Some people say the frequency should be once every 1 or 2 weeks, while others have posted promising results from doing it every day To avoid the risk of creating scar tissue, what would be the ideal frequency for microneedling?

How much pressure am I supposed to apply if I don’t want to damage hair follicles and the hypodermis? Since dermarollers are usually not recommended, I’m considering buying a dermastamp to test microneedling’s efficacy, and I will consider a dermapen in the long run.

Microneedling works for most men.  Some microneeding results parallel a good hair transplant (rare), but you will grow some hair if you do it right. For younger men, hair growth is better than in older men with long-term balding, but I have seen good results on a few men in their 50s or 60s with long-term balding, like a Class 6 pattern balding. The microneedling using a Dr. Pen device gives you control of the damage the microneedling does to stimulate hair growth.  What happens is that the microneedling produces damage at the very upper part of the hair follicle where the stem cells are present.  Bleeding is the first step, followed by migrating specialized healing cells from the body’s defenses.  Within 2-3 days, stem cells appear at the wounding site as part of the cascade of events that occur with miconeedling. These stem cells convert to hair stem cells that control hair cycling, and with enough injury frequency, the hairs in the area of wounding stimulate the hair to commence their anagen cycle.  The microneedling needs to be done once a week initially.  A maintenance schedule is required, like once a month, once the hair has grown.  Usually, a person can expect hair growth within 5-6 months or earlier.
