I hope you are on the mend and getting stronger each day. Your body has just been through a traumatic time to say the least. The healing process will be slow and this will be reflected in your hair growth. ...More >
I think it is a good idea to keep wearing a wig until your hair is at least shoulder length.
I do not think that now is the time to introduce intricate hair extension techniques to your new growth as this will add too much stress initially to the hair folicles.
Once your hair has grown back to shoulder length, I would recommend the micro ring track technique. This evenly distributes the hair extensions around your head, the technique is flate and not detectable. This would be much kinder to your hair and will encourage it to grow.
