Hair Loss: Glossary

continued...

Sprionolactone: A diuretic drug that acts as an antiandrogen. Used in the treatment of androgen related disorders such as female pattern baldness and hirsutism. Brand name: Aldactone.

Stretch Back: A condition that occurs after a scalp reduction procedure due to the elastic characteristic of the skin. The bald area that could not be eliminated totally during a scalp reduction increases in width during the months after the procedure, thus reducing the procedure's effectiveness.

Suture: Stitch.

Suture Implants: A method of attaching a hairpiece that involves sewing stitches in the scalp and securing the hairpiece to them.

Systemic Side Effects: Undesirable effects produced throughout the body. For example, some antiandrogens will cause decreased sex drive and breast enlargement in men.

Telogen: The resting phase of the hair cycle that usually lasts approximately three months.

Telogen Effluvium: The second most common form of hair loss (androgenetic alopecia is the first). A condition that causes an increased number of hairs to enter the telogen or resting phase. The additional shedding usually occurs in response to various stresses such as emotional trauma, post-pregnancy and illness, major surgery, and certain medications. Telogen effluvium can be delayed (occurring a few months after the stressful incident) or chronic (unresolved).

Telogen Loss: Loss of hair during resting phase of hair or "natural" loss.

Temporal Recession: Hair loss in the temple region.

Terminal Hair: The coarser, pigmented hair that appears on the scalp, face, armpits, and pubic areas.

Testosterone: The male hormone released by both the adrenal gland and the testicles; it promotes the development of male characteristics.

Theory of Donor Dominance: Scientific basis for hair transplantation stating that hair's genetic code resides within the hair follicle and not in the recipient site into which it is transplanted.

Tinea Capitis: Any of a number of contagious skin diseases caused by several related fungi, characterized by ring-shaped, scaly, itching patches on the skin.

Tissue Expansion: A method used to increase the effectiveness of surgical hair restoration. A balloon-like device is inserted under the scalp several weeks before the procedure and is gradually inflated weekly with saline.

Topically: Directly applied on the skin.

Traction Alopecia: This refers to hair loss that occurs due to traction placed on hair. Traction alopecia is commonly seen with braids, pony tails, and other hairstyles that create traction on the scalp.

Tretinoin: The generic term for the medication Retin-A, most commonly prescribed for acne.

Trichotillomania: A type of alopecia caused by the constant pulling and twirling of a specific area of scalp. The hair loss usually improves once the habit is stopped; however, in some severe cases it is permanent.

Tunnel Graft: A method of attaching a hairpiece that involves taking skin grafts from behind the ear or from the hip and attaching them to the scalp. Hairpiece clips can be fastened to them, thus securing the hairpiece in place.
