The difference between 4500 and 5000 hair transplant procedures lies in the quantity of transplanted hair follicles during the operation. In a 4500-follicle procedure, approximately 4500 individual hair follicles are extracted from the donor area (usually the back of the head) and transplanted into balding or thinning areas. In a 5000-follicle procedure, this number increases to around 5000 follicles. The choice depends on the extent of hair loss and the desired coverage area. Typically, a higher follicle count provides greater coverage and density, making it suitable for individuals experiencing more significant hair loss. It is important to consult with a specialist to determine the appropriate follicle count.
