i dont know exactly about the speed. it has 5 different speeds. i often set it as 2 or 3 level!!!
this is my result: i use minoxidil twice a day.
I'm not sure if i had any improvement!!!
first day:
after 1 month:
after 50 days:
after 2.5 months
i have tried to take picture in the same light but there could be some differences!!! its in the same room the same light and same hair length. i go to a hair dresser and cute my hair every two weeks. then i got a shower and took this pictures.
in all the pictures, my hair length is 1.6 cm
i've added zix and a peptide serum to my daily regime since 2 weeks ago.
the interesting part is i have bout a pen microscope so i could count my hair density!!!
my donor hair is between 180 to 210 hair per cm.
the thinner parts also is between 170 to 200. my hair count is the same almost everywhere. just it's thin in my frontal part and the crown.
i didn't loose density its just thin. if i can thicken my hair, that would be a great success.
