A: Yes, if they were effective in increasing testosterone then they may accelerate hair loss.

A: Cloning generally refers to the multiplication of fetal stem cells or embryonic tissues. “Hair cloning”, as the term is generally used, involves the multiplication of adult tissue cells that are used to induce the formation of new hair, so the term is not exactly accurate.

“Hair multiplication” refers to the multiplication of adult hair structures. This model is not actively being pursued since the hair follicle is too complex to be simply cultured in a tube. Instead individual cells called fibroblasts are removed from the scalp multiplied in tissue culture and then these are injected back into the scalp in the hope that they will induce intact follicles to form.

“Follicular neogeneis” is probably the best of these terms, as it describes the formation of new follicles derived from inducer cells that are cultured and then injected into the scalp. It is the preferred term of Ken Washenik at Aderans. Interctyex uses the term “follicular cell regeneration” for its technology.

A: Yes. The presence of miniaturization (decreased hair diameter) in the areas of thinning allows us to distinguish between hair loss due to heredity (i.e. androgenetic alopecia) in which hair progressively decreases in diameter under the influence of DHT and other causes such as stress where there is no miniaturization. The degree of miniaturization can be assessed using a hand-held instrument called a densitometer.

The pattern of hair loss and the family history are also important in the diagnosis.

Stress more commonly produces telogen effluvium, a generalized shedding that is not associated with miniaturization and is often reversible without treatment.

A: “Alopecia” is just a generic term for any kind of hair loss.

It sounds like you have a specific condition called alopecia areata. Alopecia areata is an autoimmune disease that presents with the sudden appearance of well localized bald spot(s) on the scalp or other parts of the body. The underlying skin is always normal.

The treatment is injections with cortisone. Hair transplant surgery is not indicated for this condition.

You should see a dermatologist to confirm the diagnosis and treat.

Other diagnoses to consider are triangular alopecia (which would have been present since childhood) and traction alopecia (that is cased by constant tugging on the hair).

A: They can. In women there is a delicate balance between the androgens, i.e. testosterone and estrogens. Estrogen is protective to some degree against hair loss, which is why most women don’t experience such severe hair loss as do men.

When a woman takes testosterone supplements, it upsets that balance and can cause hair loss.

However, hair loss in post-menopausal women is usually due to age related changes. Typically, the hair decreases in size in a genetically determined progression that seems not to be directly related to changes in the levels of hormones.
