I would speak to a specialist about this matter.
But in the meantime,
I read a post on another hair site about a woman who experienced a similar situation to yours. People recommended oil mixes with jojoba oil, vitamin E, Peppermint, rosemary or basil (I like to combine peppermint & rosemary EO) essentail oils as they stimulate hair growth. It was also advised that she massage her scalp every day and avoid wearing hair bands or anything that pulls the hair back. Finger combing your hair is essential and always look at the ingredients of the products you are using.
Hope that helps.
