I met a guy who is trying to lock his hair but wasn’t sure which style to use to lock. When he visited the loctician, threading was suggested to him.
Threading of locks is done by first subdividing the hair into rectangles (sometimes it's an undescribable shape) and then tying the thread loosely along its whole length to form a lock. Space the thread along the lock length NOT like the raffia locks though (it is quite complex trying to explain this style so I made pictures of the locks, hope they give a better understanding of the technique). It is preferable to use black thread if your hair is black. Later as the hair grows out, you twist the root with hair gel or beeswax.
This method is just a starting method to help make the locks lock faster and equally through the whole length of a lock. This method is usually used on long hair. DO NOT tie the thread too tight cause then the lock will develop with bumps on it. Tie it lightly but firmly enough to hold the lock in place.
