The loss you have experienced is often temporary. Be aware that over the long term, wearing a hairstyle that is too tight (like weaves or braids) can cause "traction alopecia." This is often permanent. Topical Rogaine can help stop the ongoing hair loss. If you need an increase in density to cover bare areas of scalp, then hair transplantation surgery is in order. So that you can get a diagnosis and all of your options, please make an in-person consultation with an experienced hair transplantation surgeon near you. We have done hair restoration surgery on many a patient with traction alopecia and have seen excellent results. The hair is permanent and natural. The donor site scar is nearly imperceptible. The procedure is done in our office, under local anesthetic, and in a single session. Best of luck, Dr. P
