A

Hair loss.

This is the first stage of the hair cycle where hair grows for an extended period of time averaging 3-5 years (see Catagen Phase and Telogen Phase).

ARTAS is the most advanced Follicular Unit Extraction (FUE) hair transplant available in the industry.  It is the only true ‘robotic’ procedure, and must be performed by a licensed doctor.  All other FUE procedures can be done by a technician. [more]

B

Hair transplant procedure where hair is taken from the donor area and transplanted to thinning, patchy areas in the beard. [Learn More]

The innermost section of the hair follicle, housing the hair matrix responsible for generating the hair shaft, governing hair growth, and producing pigmentation.

C

This is the second stage of the hair cycle following the Anagen Phase where hair is in a temporary state lasting only two to three weeks before moving to the Telogen Phase. (see Anagen Phase and Telogen Phase).

Topical powder used to help conceal hair loss or a poorly done hair transplant scar.

D

Condition where thinning occurs all over the entire head.

The area in the back of the head extending from ear to ear containing hair follicles that are permanently resistant to DHT which causes hair loss. [Learn More]

E

When a Phlebotomist draws fluid from your own body and spins it in a specially designed centrifuge where tissue healing fluid is isolated and reintroduced into thinning areas through injection. [learn more]

F

See Pattern Baldness.

When individual hair follicles are extracted from the patient’s donor area and transplanted (moved) to balding areas leaving small circular scars. [Learn More]

When a thin strip of tissue is extracted from the patient’s donor area and divided into small grafts to be transplanted (moved) to balding areas leaving a thin linear scar.

G

Tissue containing one or more hair follicles to be used in a hair transplant.

H

When donor hair is harvested for a hair transplant but dies prematurely due to extended time outside the body.

A naturally occurring tube-like tissue, which we often refer to as a bundle, that surrounds the strand and the root of one or more hairs.  

One of three different phases of hair growth.  See anagen, catagen, or telogen. 

Terminology referring to an older style hair restoration technology prior to the late 90’s where follicles contained too many hairs and were spaced too far apart, leaving unsightly evidence that a hair transplant had been done. Hair plugs resemble the appearance of hair on a toy doll’s head.

A hair transplant is a surgical procedure where healthy growing hair is relocated to a balding area. [Learn More]

L

An FDA approved hair regrowth therapy that utilizes safe, painless laser light to strengthen and regrow failing hair. Equipment varies from industrial strength to home devices. [Learn More]

M

See Pattern Baldness

Micropigmentation is a non-surgical hair restoration technique that minimizes the appearance of baldness or thinning by embedding colored pigment into skin. [Learn More]

Multi-Unit Hair Grafting™ is a trademarked hair transplant developed at PAI Nashville. It delivers double the density when compared to other procedures across the nation.[Learn More]

N

When skin tissue in the transplanted area dies due to compromised blood supply.

P

For men, pattern baldness is called male pattern baldness, and for women, it’s called female pattern hair loss. Both types of pattern baldness are genetic in nature where loss occurs in the temple areas, the vertex and crown. Hair in this area is genetically more susceptible to DHT, a hormone that causes hair loss.

R

When a surgeon creates incisions in the balding area where new hairs will be placed.

S

See donor area. [Learn More]

T

This is the final stage of the hair cycle following the Catagen Phase where hair goes into a resting phase before falling out. This cycle generally lasts for two to three months before the follicle produces a new hair and the growth cycle starts over (see Anagen Phase and Catagen Phase).

Thick, pigmented hair

When the base of a hair follicle is damaged or destroyed as it is harvested.

Specially developed, extremely thin suture closure that overlaps at an angle, allowing hair to grow through the scar remnant while camouflaging its appearance.

V

Short, fine, non-pigmented hair
