Procedures Offered

FUE
FUE (Follicular Unit Extraction) is a minimally invasive hair transplant technique where individual hair follicles are extracted one by one from the donor area using a small circular punch tool. The harvested follicles are then carefully implanted into the balding or thinning areas of the scalp. This method leaves tiny, nearly invisible scars rather than a linear scar, resulting in faster healing and the ability to wear shorter hairstyles. Because of this, FUE is the most popular hair transplant technique today.
