Hair Transplant Jargon Buster: Glossary terms you need to know

Understanding the terminology associated with hair transplantation can help you make informed decisions about your treatment. Below is a comprehensive glossary of key terms used in the hair restoration industry, along with expert insights from Dr Matee, Director of Surgical Services at KSL Clinic.

Alopecia

A medical term for hair loss. There are several types, including:

• Androgenetic Alopecia: Commonly known as male or female pattern baldness, it is a genetic condition that leads to progressive hair thinning.
• Alopecia Areata: An autoimmune disorder causing patchy hair loss.
• Scarring Alopecia: A condition where inflammation damages hair follicles permanently, making hair transplantation less effective.
• Traction Alopecia: Hair loss caused by excessive pulling or tension on hair follicles, often due to tight hairstyles.
• Telogen Effluvium: Temporary hair loss due to stress, illness, or hormonal changes.

Anagen Phase

The active growth phase of the hair cycle. Hair transplants are most successful when existing hair is in this stage, ensuring natural blending with transplanted follicles.

Catagen Phase

A short transition phase where hair growth slows, and the follicle prepares to enter the resting phase.

Telogen Phase

The resting phase of the hair cycle where hair is shed naturally before new growth begins.

Donor Area

The region of the scalp (usually the back or sides) where hair follicles are harvested for transplantation. This area is typically resistant to DHT, the hormone responsible for pattern baldness.

DHT (Dihydrotestosterone)

A hormone linked to androgenetic alopecia. DHT-sensitive hair follicles shrink over time, leading to hair thinning. Medications like Finasteride help block DHT to slow hair loss progression.

FUE (Follicular Unit Extraction)

A minimally invasive hair transplant method where individual follicles are extracted and transplanted. It results in minimal scarring and a faster recovery time.

FUT (Follicular Unit Transplantation)

Also known as the strip method, this technique involves removing a strip of scalp, dissecting it into follicular units, and transplanting them to the thinning areas. FUT typically provides a higher graft yield but leaves a linear scar.

Graft

A follicular unit (containing 1-4 hairs) that is transplanted to a new location. The number of grafts needed varies based on hair loss severity and the desired density.

Hair Density

The number of hair follicles per square centimetre on the scalp. A successful transplant aims to restore natural-looking density, especially in the hairline and crown areas.

Hairline Design

A crucial aspect of hair transplantation that determines how natural the results appear. A skilled surgeon considers facial structure, age, and existing hair patterns when designing a new hairline.

Ludwig Scale

A classification system used to measure the extent of female pattern hair loss.

Norwood Scale

A classification system used to measure the extent of male pattern baldness.

Minoxidil

A topical medication that stimulates hair growth and prolongs the anagen phase. Often used alongside hair transplants to enhance results and slow further hair loss.

Platelet-Rich Plasma (PRP) Therapy

A non-surgical treatment where plasma from the patient’s blood is injected into the scalp to stimulate hair follicles and encourage growth. PRP hair treatment can be used as a standalone treatment or combined with a hair transplant for better outcomes.

Recipient Area

The area of the scalp where harvested follicles are implanted to restore hair growth.

Shock Loss

Temporary shedding of transplanted or surrounding hair post-surgery. This is a normal reaction to the procedure, and hair regrows within a few months.

Survival Rate

Refers to the percentage of transplanted grafts that successfully grow new hair. Factors like proper technique, surgeon skill, and post-transplant care influence the survival rate.

Transection Rate

The percentage of hair follicles that are accidentally damaged or destroyed during the extraction process.

Temporal Peaks

The small, pointed areas at the corners of the forehead that frame the hairline. Proper restoration of these peaks is key to a natural-looking transplant.

UV Protection Post-Surgery

Newly transplanted grafts are sensitive to sunlight, and excessive UV exposure can affect healing and growth. Wearing a hat or using SPF is advised in the early stages of recovery.

Dr Matee’s Advice on Understanding Hair Transplant Definitions

“Navigating hair transplant terminology can feel overwhelming, but understanding these key terms will help you make informed decisions about your treatment. From recognising the difference between FUE and FUT to knowing what factors impact graft survival rates, a solid foundation of knowledge ensures you choose the right procedure for your needs. Always consult with a trusted clinic to discuss the best approach tailored to your hair loss journey.”
