Kumpulkan helai rambut. Potong rambut. Masukkan rambut ke dalam kantong.

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
Find a hairbrush with hair in it. Remove the hair and place it on a piece of paper. Use scissors to cut the hair into tiny pieces. You should have a pile of cut hair. Pick up the paper and slide the hair into a sealable plastic bag. You can also slide it into an envelope. Store the bag in a cabinet for later use.
