Liz Marie, Thank you but can you expound on this microneedler device? I guess it stimulates the scalp? Is it used along with Minoxidil? Where can I or we purchase one direct, a little $ is just fine if this combination will really help. Thank you so much. I'm so tired of receiving Paula Young catalogs I could just scream.
I am sorry I missed this earlier, Francis!
Microneedlers can be bought at Amazon for usually $12-$18. Once you have one, it will basically last years and years unless you abuse it.
The study I linked described the usage pattern. Normally Minoxidil is applied twice per day, seven days per week.
However, when microneedling, you use Minoxidil twice per day six days per week. On the seventh day you microneedle the scalp. The study again describes how much, basically until the scalp is left red but not bleeding.
The device has hundreds of tiny needles on it. Rolling it back and forth across the entire scalp basically produced thousands of "micro-trauma" sites that are punctures of the epidermis but not deep enough to bleed. This stimulates any stem cells in the scalp to move to the micro-trauma site and begin repairs - aka cell growth. Since Minoxidil encourages formation and growth of hair follicles, more micro-trauma sites means more chances for Minoxodil to cause a hair follicle to form instead of just skin cells.
According to the study, standard Minoxidil control patients (7 days a week twice a day) generated 22 hairs per square centimeter. Microneedling patients, however, generated an average of 96 hairs per square centimeter, more than 4 times as many as standard Minoxidil usage. Note that normal hair density is in the 100-150 hairs per square centimeter range so the micro-needling approach almost generates normal hair cover for
some patients. (It's an average so some got more and some less.)
