GLOSSARY:

ALOPECIA: hair loss, especially on the head, due to multiple factors. It can feature as a

complete absence of hair. It can either be areata (i.e. limited to patches) or universalis (i.e.

affecting the whole body).

WIG: – Little hair prosthesis used to hide baldness in the front or back part of the scalp.

TRICOGRAPH: precision tool used to specifically treat the scalp.

NEEDLE OR APPLICATOR: metal surgical tool specifically designed to transport pigment

inside the scalp.

JELLY MAKER: pigment stabilizing factor used during Tricopigmentation.

PIGMENT: a dry insoluble substance, usually in powder form, which, when suspended in a

liquid vehicle, becomes a paint, ink, etc. Any substance, whose presence in the tissues or

cells of animals or plants paints them.

RED ICE: skin vasoconstrictor and thermoregulator used to stabilize the pigment.

DIASTASIS: in the medical field, an abnormal separation of parts normally joined together.

KELOID: a hard smooth pinkish raised growth of scar tissue at the site of an injury, tending

to occur more frequently in dark-skinned races.

GRAFTING: the action of surgically transplanting a portion of living tissue from one part of

an individual to another, or from one individual to another, for its adhesion and growth.

FUE: Follicular unit extraction (FUE), also known as follicular transfer (FT), is one of two

primary methods of obtaining follicular units, naturally occurring groups of one to four

hairs, for hair transplantation. The other method is called strip harvesting. In FUE

harvesting, individual follicular units are extracted directly from the hair restoration patient’s

donor area, ideally one at a time. This differs from strip harvesting because, in strip

harvesting, a strip of skin is removed from the patient and then dissected into many

individual follicular units. The follicular units obtained by either method are the basic

building blocks of follicular unit transplantation (FUT).

Nowadays FUE technology has grown into Advanced FUE. The main difference is that

Advanced FUE enables the creation of larger donor pools by harvesting follicles from

areas outside the head such as: chest, legs, arms, abdomen, back, face, and beard. Also

Advanced FUE addresses the fact that hair often grows in a curved trajectories. With

standard FUE surgical there is the assumption that this growth occurs as a straight line.

This entails a risk of damaging the follicles during the excision and retrieval of the grafts.

STRIP: Strip harvesting is the most common technique for removing hair and follicles from

a donor site. The surgeon harvests a strip of skin from the posterior scalp, in an area of

good hair growth. A single-, double-, or triple-bladed scalpel is used to remove strips of

hair-bearing tissue from the donor site. Each incision is planned so that intact hair follicles

are removed.

The excised strip is about 1–1.5 x 15–30 cm in size. While closing the resulting wound,

assistants begin to dissect individual follicular unit grafts, which are small, naturally formed

groupings of hair follicles, from the strip. Working with binocular Stereo-microscopes, they

carefully remove excess fibrous and fatty tissue while trying to avoid damage to the

follicular cells that will be used for grafting. The latest method of closure is called

‘Trichophytic closure’ which results in much finer scars at the donor area.

DERMATITIS: an inflammation of the skin. Itching and redness are the basic symptoms of

dermatitis, which has a variety of causes, including allergies and exposure of the skin to

irritants, such as chemicals or sunlight.

DERMATOSIS: skin disease, especially one that is not accompanied by inflammation.

PSORIASI: skin disease characterized by the formation of reddish spots and patches

covered with silvery scales: tends to run in families.

SEBORRHEA: an excessive and abnormal discharge from the sebaceous glands.

TRICOSHAMPOO: specific acid-pH detergent used in the post-Tricopigmentation home

care.

POST-TRICOPIGMENTATION SERUM: serum specifically designed for the post-

Tricopigmentation home care. It has a protective, anti-reddening, anti-itching, pigment

fixative function.

TRICO WASHER: professional detergent specifically used to clean and sterilize the scalp

during Tricopigmentation treatments.

HAIRLINE: area of the forehead or of the frontal bone.

PARIETAL: side and top of the skull or the parietal bone.

OCCIPITAL:  bone forming the back and back part of the base of the cranium, the part of

the skull that encloses the brain. It has a large oval opening, the foramen magnum,

through which the medulla oblongata passes, linking the spinal cord and brain. The

occipital adjoins five of the other seven bones forming the cranium: at the back of the

head, the two parietal bones; at the side, the temporal bones; and in front, the sphenoid

bone, which also forms part of the base of the cranium.

MID SCALP: In the field of hair transpant and Tricopigentation, the area comprised

between the front scalp and the vertex/crown.

VERTEX: the topmost point of the vault of the skull; the crown of the head.

MYCOSIS: the presence of parasitic fungi in or on any part of the body. The condition

caused by the presence of such fungi.

KERATINE: a fibrous protein that occurs in the outer layer of the skin and in hair, nails,

feathers, hooves, etc.

EPIDERMIS: the outer, nonvascular, non-sensitive layer of the skin, covering the true skin

or corium.

DERMIS: the dense inner layer of skin beneath the epidermis, composed of connective

tissue, blood and lymph vessels, sweat glands, hair follicles, and an elaborate sensory

nerve network.

HYPODERMIS: a tissue or layer of cells beneath the epidermis.

FOLLICLE:  any small sac or cavity in the body having an excretory, secretory, or

protective function (e.g. a hair follicle)

MACROFAGE:  a large white blood cell, occurring principally in connective tissue and in

the bloodstream, which ingests foreign particles and infectious microorganisms by

phagocytosis.

FAGOCITOSIS: The process of engulfing and ingestion of particles by the cell or a

phagocyte (e.g. macrophage) to form a phagosome (or food vacuole), which in turn fuses

with lysosome and becomes a phagolysosome where the engulfed material is eventually

digested or degraded and either released extracellularly via exocytosis, or released

intracellularly to undergo further processing.
