What are the different kinds of locking techniques for black hair and how do they work?

I'm a cosmetologist, and when locking your hair there is mainly on way. some ppl use extentions in their locks, but those are usually temporary. and their is locking the natural hair. but mainly are the same. u should clean your hair first. u may want to make sure u dry your hair. section the hair in parts like u would do single strand braids, take some bee's wax one each section and roll it with your hands, or spiral roll it with a rat tail comb. make sure u roll them pretty tight. u can make them as big or small as u want. it takes at least 6-12 month for them to completely lock. so u will want to every few week or more. to rub them in your hand to make the locks tighter. the more u do that, with time it will lock completely. but i do suggest trimming the outer strands of the locks to make them look neater. hope this helps
