Male Hair Loss- Some Causes and
Treatments
What causes male hair loss? There are
many answers to this question, but in truth only a doctor can make a
concrete determination. First, medical causes like thyroid imbalance,
lupus, diabetes, liver disease and kidney disease must be ruled out. This
necessarily involves traditional medical tests prescribed and evaluated by
a physician. Your male hair loss, if it has an underlying medical cause
like thyroid imbalance, can be treated and possibly reversed.
Your doctor may diagnose you with
androgenic alopecia or alopecia areata as causes of your male hair loss.
Androgenic alopecia is commonly known as male pattern baldness and occurs
as the result of a complex set of genetic, hormonal and enzymatic
interactions. Alopecia areata is thought to be an autoimmune disorder in
which the body's immune system destroys body tissues (like hair) that it
normally would ignore. Alopecia areata is treated with medium to very high
potency topical corticosteriods, subcutaneous steroid injections and
ultraviolet light.
Androgenic alopecia is by far the most
common cause of male hair loss. Hair begins to thin at the temples,
frontal hairline and crown. Over time hair will be completely lost in
these areas, resulting in a fringe of hair remaining at the sides and back
of the head only. The process of androgenic alopecia is thought to be
genetically linked, that is, the follicles in the areas of the head
experiencing balding are inherit a sensitivity to the action of a hormone
called DHT or dihydrotestosterone. DHT is formed when the hormone
testosterone is converted via the action of an enzyme named 5-alpha
reductase.
An overabundance of DHT in a man's body
causes the DHT that is present in the scalp to attack follicles that are
genetically predisposed to be sensitive to it. DHT works to make the
follicle miniaturize, with the result that the hairs produced become
thinner and thinner. Eventually the hair becomes transparent and the
follicle becomes inactive -- it stops producing hair. Note that only
susceptible follicles are affected. The hair at the sides and back of the
head is naturally resistant to the action of DHT -- an important fact to
know when considering treatments for male hair loss. This resistant hair
can be transplanted to balding areas to recreate your hairline.
Treatments for androgenic alopecia
include drugs that block the action of DHT. These drugs may be combined
with growth stimulators that cause the follicle to produce hair despite
the action of DHT. The best-known DHT blocker is the prescription drug
PropeciaŅ, generic name finasteride. Finasteride actually works to block
the action of the 5-alpha reductase enzyme that is responsible for turning
testosterone into DHT. In a clinical study, 64% of patients who took this
drug for male hair loss experienced hair regrowth after to 2 years. The
drug is even more effective in helping you keep the hair you have.
The most familiar growth stimulant is a
non-prescription topically applied product named RogaineŅ, generic name
minoxidil. In a clinical study, 59% of male hair loss sufferers began
regrowing hair within 4 months. Minoxidil may also be a good preventative.
The best regimen is a combination of
finasteride and minoxidil as a treatment for male hair loss caused by
androgenic alopecia. See your doctor first. If you have androgenic
alopecia, there are potent medicines to help you combat it.
