Topical powder used to help conceal hair loss or a poorly done hair transplant scar.
Anagen Phase (hair cycle):
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).
Catalan Phase (hair cycle):
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).
Telogen Phase (hair cycle):
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).
Diffuse Hair Loss:
When hair thins all over the head including the ‘safe zone’ which is normally resistant to hair loss. Those with diffuse hair loss are not candidates for a hair transplant but other hair restoration modalities may help.
Donor Area (Donor Hair):
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.
Female Pattern Hair Loss:
See Pattern Baldness.
Tissue containing one or more hair follicles to be used in a hair transplant.
When donor hair is harvested for a hair transplant but dies prematurely due to extended time outside the body.
A naturally occurring bundle of tissue containing one or more hairs.
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.
Male Pattern Baldness:
See Pattern Baldness.
Multi-Unit Hair Grafting™:
PAI Medical Group’s trademarked, specially developed hair restoration procedure that yields twice as much hair when compared to traditional FUT procedures. The secret is in the specialized graft sizes and the tricophytic closure.
When skin tissue in the transplanted area dies due to compromised blood supply.
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.
When a surgeon creates incisions in the balding area where new hairs will be placed.
See donor area.
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.
When DHT resistant hair is harvested from the patient’s donor area and transferred to thin patchy areas in the eyebrows to make them look thicker in appearance.
FDA approved medication used to treat pattern baldness. This prescription drug slows hair loss and sometimes improves hair growth. (Propecia, Proscar)
FUE Hair Transplant:
When DHT resistant hair follicles are extracted directly from the patient’s donor area one follicle at a time using either a manual or robotic device and transplanted (moved) to balding areas. (ARTAS, Neograft)
FUT Hair Transplant:
When a segment of linear tissue containing DHT resistant hair follicles is harvested from the donor area and manually separated into individual bundles of hair by a technician to be transplanted into balding areas. (Muti-Unit Hair Grafting™)
Low Level Laser Therapy:
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.
When colored cosmetic pigment is embedded in balding areas to give the appearance of hair.
A topical formula that improves blood flow in the scalp and increases hair growth primarily in the crown and mid-scalp areas. (Rogaine)
Platelet Rich Plasma (PRP) Treatment:
When a patient’s blood is drawn and separated in a centrifuge, which isolates the reparative rich platelets responsible for healing. The platelets are then combined with A-Cell and reintroduced through injection into balding areas to stimulate hair re-growth.
Androgenetic Alopecia (Pattern Baldness):
Genetic hair loss that occurs in the temples, on the top of the head or the crown but not in the DHT resistant donor area.
Auto Immune condition that causes patches of hair loss.
Auto Immune condition that attacks all the hair follicles even on other parts of the body such as the eye lashes and eye brows.
Diffuse Hair Loss:
When thinning occurs all over the entire head.
Temporary hair loss due to hormones after pregnancy.
When hair follicles become permanently damaged and scarring occurs due to pony tails, braids or other hair styles that involve excessive pulling.
