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
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
POST-TRICOPIGMENTATION SERUM: serum specifically designed for the post-
Tricopigmentation home care. It has a protective, anti-reddening, anti-itching, pigment
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
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
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
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.
