Hello,
From the symptoms it looks like traction alopecia. Traction alopecia is caused by gradual hair loss, caused primarily by pulling force being applied to the hair. Treatment includes topical and oral antibiotics and surgical hair transplantation procedures. I suggest you to get it evaluated from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
