This article introduces some important terms related to hair transplant surgery. Understanding the terminology involved in the surgery, such as hair follicle, follicular unit (FU), hair density, and donor area, will help you understand the mechanics and process of hair transplant surgery. Male pattern baldness (AGA) and the importance of transplanted hair follicle placement will also be explained to help you achieve a natural look.
List of terms for hair restoration surgery
Hair follicles (HF) Hair follicles are the tissues that drive hair growth and are a key component of transplant procedures.
Follicular Unit (FU) The follicular unit is a cluster of tissue from which hair grows and is the basic unit that is surgically transplanted .
Graft transplantation is the surgical process of transferring hair or hair follicles from a donor area to a recipient area .
Hair Density (HD) Hair density is a measure of the number of hairs present in a particular area. It is calculated as FD x the number of hairs in a single hair follicle. The number of hairs varies, with most hair follicles having between one and four hairs.
Hair Follicular Density (FD) Hair Follicular Density is a measure of the number of hair follicles present in a particular area.
Hairs per follicular unit (FU) or Hairs per hair unit (HFU) HFU is a measure of the number of hairs contained in one follicular unit.
Transplanted Hair Follicle Density (TFD) TFD is an indication of the density of transplanted hair follicles .
Hair and hair follicle viability Hair and hair follicle viability is an indicator of the survival rate of transplanted hair and hair follicles.
Donor HairDonor hair refers to healthy hair that is used for transplantation .
Androgenic alopecia ( AGA ) Androgenic alopecia ( AGA ), the most common form of hair loss
AGA is one of the most common forms of hair loss among men and women. Male pattern baldness has different characteristics for men and women.
Donor dominance as a basis for hair transplantation Donor dominance is one of the fundamental principles of hair transplant surgery, which means that hair from the donor area tends to survive longer in the recipient area.
Donor Area The donor area is the source of healthy hair that is used to extract hair.
Recipient Area The recipient area is the area where the transplanted hair will be placed and is the area that will be targeted for hair loss treatment.
Placement ofgrafts The placement of grafts in a hair transplant procedure plays a key role in the success of the procedure. Accurate placement of grafts ensures a natural appearance and adequate density. This process requires careful planning and expertise, and experts often determine the best placement method depending on the patient’s individual needs.
