It is very tough to have someone release your hair especially if her hold is really secure and she has a lot of it in her grip, also depends where on the scalp she has that grip, cause while any hair pull hurts and can control certain areas are a lot more painful than others, but one method is to while a free hand swings slap or punch or even go after her top , tend to make other let go of the hair as she has to not only return a blow or cover up she has to let go to avoid being pummeled , another way is t whip her to the ground by her hair and straddle her be it on her back or on top of her front looking down, it is not always a promise she will let go but a persons first instinct is to have hands free to lessen the hard landing so brace the fall or thrown to ground effect, if both are standing bent over at the waist, your already kind of fighting blind, cause most of what you see are her legs , feet and the ground. another way is to take the extreme painful burn and force your head up against her pull, typically means your gonna lose a fistful at the least, but if you can withstand it you have her at a disadvantage once your head are and can really go at her.
Another way is to get a limb or neck in a really pain filed hold, i.e. arm bar twisting , ankle or knee hold, choke or even a breast hold that hurts, sometimes a kick or stomp to the ankle, knee or foot, a well placed punched to the nose will make most let go of any hold as it stuns, and again instinct most will cover or try to protect the face even for a second can be all you need to get your hair free. there are more technical ways like fall on your back as you pull her on you a foot in her tummy and throw her over you can work, and a well placed scratch to the face will work as well.
