Tell us about yourself!
you do not need to cut your hair, just make a simple wooden comb with 5 spikes, brush your hair regularly, then collect all of the hair that falls out and put onto a spindle. it accumulates very quickly.
you can also make rope and other things from your own hair, provided you are letting it grow out. A lot of tribes use their own hair in jewelry making and rope making because it is so durable, strong, and attractive looking (shiny and smooth if weaved correctly).
