Things you will need:

1 electric hair clipper.

1 head and shoulders.

1 bottle of aftershave cologne.

First wet your hair with water. Make sure it is an even distribution or else your hair will get entangled in the clippers. 

Once you've achieved the desired wetness, turn on the electric razor. I suggest you put it at 0" (without any accessory comb) for optimal usage. Now slowly start mowing your hair down, a stroke at a time. You should check yourself in the mirror to see you are getting an even cut.

Repeat for the remaining length of hair until you can see nothing but your dandruff infested scalp. Once done, it is time to wash your bald head.

Apply generous portions of Head and Shoulders onto your scalp. Use a metallic scrub if needed to scrape the dandruff fungus from off your scalp. The jumras love to mate in this gooey substance.

Once your scalp is shiny, pat it down with aftershave. It might burn a little but it will help decontaminate the area.

Look at yourself in the mirror and smile. You have successfully gotten rid of the Nepali jumra. 

Subtle notice: this only removes jumra from your cranial hair. For all other infected sections, the process might not be as easy and you might have to buy additional accessories.

Have a nice day :)
