Yes, shave it down and do this regimen. You will easily get 100 percent of it back if you do it every day. This is what I do.
Finasteride. No side effects at all.
Minoxidil morning and night. Plus .5 dermapen for absorbtion every morning.
I take Sawpalmetto(blocks dht), Pygeum(blocks dht), biotin. Coconut oil+cayenne pepper oil mixture every day or other day for 30 minutes or more.(cayenne blocks cannibinoids from marijuana use, which can cause hair loss. And it stimulates new hair growth).
I use an inversion table about 15 to 30 minutes a day spread out in like 5 minute increments.
I massage coconut oil with a brush on my scalp for around 10 minutes a day or other day. Brush or fingertips. Doesnt matter.
Also I do fingernail rubbing around 10 minutes a day throughout the day.(stimulates the hair follicles).
