Minoxidil for male
Minoxidil has a hair
growth promoting effect on pattern baldness
affected hair follicles.
Minoxidil was originally introduced in the early 1970s as a treatment for hypertension. Minoxidil is in the class of treatments called "Potassium Channel Openers" that are used primarily for treating persons with high blood pressure. Although several potassium-channel openers have been used in research for many years, Minoxidil is the only approved one in this category of
drugs for use in humans.

Although it is clear that Minoxidil stimulates
hair growth, our understanding of its mechanism
of action on the hair follicle is very limited.
Drugs may stimulate hair growth in various ways.
They may increase the linear growth rate of
hair, increase the diameter of the hair fiber,
alter the hair cycle, either by shortening telogen (resting phase) or prolonging anagen
(growth phase), or hair follicles may respond to
act through a combination of these effects.
Minoxidil does not appear to have either a
hormonal or immunosuppressant effect. However,
it has been shown to have a direct mitogenic
effect (i.e. it induces cell division) on
epidermal cells both in vitro and in vivo.
Despite untiring efforts by researchers, we
still have only a limited understanding of how
hair follicles respond to Minoxidil stimulation.
Finasteride for male
Finasteride (Propecia)
is an approved treatment for male pattern
baldness
The use of Finasteride (brand name propecia), a
synthetic 4-azasteroid compound, is indicated in
men older than 18 years with mild to moderate
male pattern hair loss. The underlying principle
behind the use of this drug in male pattern hair
loss is the reduction of dihydrotestosterone (DHT)
production; thus limiting the action of DHT on
scalp hair follicles.
Finasteride (1 mg daily) has been approved for
the treatment of male pattern hair loss in the
United States as well as in several European
countries. It has been found that oral
Finasteride at doses of 1 and 5 mg per day
causes a marked suppression of serum DHT of 71.4
and 72.2 percent, respectively and suppression
in the scalp DHT of 64.1 and 69.4 percent,
respectively. Treatment must be continued for at
least 6 months before a proper evaluation of
efficacy can be made. Although it affects vertex
balding more than frontal hair loss, the
medication has been shown to increase re-growth
in the frontal area as well.
Finasteride is available as the brand name
Propecia, which was developed to treat male
pattern hair loss in the vertex and anterior
mid-scalp area. Propecia is proven to maintain
or increase hair count in most men.
Small-scale, variably controlled studies
conducted on a primate model for androgenetic
alopecia and on young men with mild to moderate
male pattern hair loss showed that combination
of Finasteride and Minoxidil may be more
effective than any one drug alone, but further
investigation is needed to sustain this theory.
Side effects in Men
Some common side effects of Finasteride
treatment in men according to authors are
decreased libido, decreased semen volume, and
erectile dysfunction, with each occurring in
fewer than 2 percent of men younger than 41
years and slightly more often in older men.
Contrarily, a recent study by Overstreet et al
showed that Finasteride 1mg daily for 48 weeks
does not affect spermatogenesis or semen
production in men aged 19 to 41 years.
Many recipients of this drug are elderly men
taking 5 mg per day. There is no effect of
long-term use on bone mineral density.
Reversible painful gynaecomastia (abnormal
enlargement of the male mammary glands) has been
reported and the incidence is thought to be
around 0.001 percent. Many of these adverse
effects in men on Finasteride resolved while
they remained on drug itself, and any remaining
adverse effects were cleared up once the drug
was stopped. With regards long-term safety,
Finasteride for men has now been in medical use
for over 10 years.
Antiandrogens for male
Topical anti androgens
are used by some to treat their pattern hair
loss
Hamilton observed that when men with male
pattern baldness were castrated it prevented
further progression of hair loss; and that the
hair loss in eunuchs induced by exogenous
testosterone halted when testosterone treatment
was discontinued. This leads to the assumption
that it would be feasible to use an antiandrogen
to halt or even reverse pattern baldness in men
(and equally in women too). However,
antiandrogen therapy for androgen-induced
baldness is still in its infancy and relatively
limited information is available on how it can
be used and the appropriate formulations for
use.
Anti androgen drugs used in medicine may be
systemic or topical. Because systemic
anti-androgens reduce circulating testosterone,
which is required for normal male sexual
functioning, their use in androgenetic alopecia
is currently limited to women. A topical
antiandrogen is administered by applying the
compound to the surface of the skin, and appears
to hold promise for treatment in men as well as
women.
Ketoconazole shampoo
Ketoconazole shampoo is
a popular treatment in combination with other
treatments for pattern baldness
Ketoconazole (Brand name Nizoral) is actually a
synthetic antifungal drug used to prevent and
treat skin and fungal infections, especially in
immuno-compromised patients. This drug, an
Imidazole (an organic crystalline base that is
an inhibitor of histamine) derivative, is an
effective oral agent that has broad-spectrum
antifungal activity and is also a steroid
biosynthesis inhibitor. The androgen lowering
potential of high doses of Ketoconazole has led
to its use in the treatment of advanced prostate
cancer.
Formulated as a topical treatment, oral tablet
and as a shampoo, the drug Ketoconazole is
available by prescription. Branded Nizoral
shampoo contains 2 percent Ketoconazole and is
prescribed not only for the treatment of
infectious fungal scalp conditions, but also in
combination with other treatments for
androgenetic alopecia. Ketoconazole can cause a
reduction in the production of testosterone and
other androgens in the skin. A 1 percent version
is available over-the-counter, but it may not be
as effective as the 2 percent prescription
strength.
Tretinoin for male
Topical tretinoin is used
by some to treat male and female pattern hair
loss, sometimes in combination with minoxidil
Tretinoin essentially is a derivative of vitamin
A. Topical Tretinoin is used by dermatologists
in the treatment of mild to moderate acne and on
skin that has been damaged by excessive exposure
to the sun. Two treatment forms of retinoic acid
have been developed - all-trans-retinoic acid
and 9-cis retinoic acid.
As a retinoid that regulates the growth and
differentiation of epithelial cells, topical
Tretinoin can be used to help enhance the
effects on Minoxidil for the treatment of hair
loss. Although Tretinoin alone does not act as a
significant stimulant of hair growth, there is
some evidence that a combination of Minoxidil
(0.5%) and Tretinoin (0.025%) promotes hair
growth in men with androgenetic alopecia. This
is most likely due to the increased absorption
of Minoxidil through alteration of the horny
outer layer of the epidermis, the stratum cornum.
However, the manufactured formulations of
Tretinoin (Retin-AŽ) and Minoxidil (RogaineŽ)
are incompatible and become ineffective if
compounded in one formulation. They must either
be mixed using generic powder forms or be
applied as separate treatments. For efficacy,
RogaineŽ must be applied every morning and night
and Retin-AŽ during the day. Even though there
appears to be some benefit in using the
combination, the need for an extra application
during the day is generally considered to be
rather inconvenient, discouraging wide
acceptability. Additionally the skin irritation
caused by Tretinoin is not always well
tolerated.
Side effects
The potential side effects of topical Tretinoin
are irritation and photosensitivity .As
Tretinoin does not work alone, the potential
side effects of Minoxidil should also be
considered when administering treatment.
Concerns about increased irritation, possible
systemic absorption of drug, and difficulties
related to the use of both agents together has
led to the limited usage of this line of
treatment.
Diazoxide for male
Diazoxide is a nondiuretic benzothiazide. This
potent and rarely anti-hypertensive agent has
diverse pharmacologic effects including:
Hypertrichosis (hair growth).
Hyperglycemia associated with suppression of
insulin release, which is why it is used to
treat idiopathic hypoglycemia of infancy.
Elevation of serum levels of androgens.
Taking advantage of the hypertrichotic side
effects of diazoxide, several authors have
examined the effect of topical application of
the drug on hair re-growth in androgenetic
alopecia. A topical formulation of diazoxide was
reported in 1989 to show efficacy in male
pattern baldness. Nineteen men with "early to
midstage" androgenetic alopecia were treated
with 3% diazoxide solution twice daily for 2 to
11 months. Reports indicate that four men had a
dense growth of new hair, seven had moderate
growth by way of some new terminal hairs, one
had vellus hair growth, and seven had no
re-growth at all. Local irritation occurred in
one patient.
Estrogen for male
Topical estrogen is used by
some to treat pattern hair loss
Estrogens are indirect anti androgens,
increasing the production of sex hormone binding
globulin (SHBG) and thus leading to a decrease
in the bioactive free testosterone. SHBG, a
glycoprotein synthesized by the liver, is the
most important protein for androgen binding .The
more potent androgens and estradiol are bound in
the plasma to SHBG, although the binding
affinities differ. Elevated testosterone causes
SHBG synthesis to decrease, in addition to an
increased activity of 5 alpha - Reductase, the
enzyme responsible for the metabolism of
testosterone to DHT. Estrogens increase Sex
hormone binding globulin (SHBG) and thus further
decrease the amount of free testosterone.
Extensive clinical trials of the use of a
topical estrogen preparation in subjects with
androgenetic alopecia have been not been
conducted as yet. However, one double-blind,
controlled, 6-month trial of topical 0.025% 17
alpha - estradiol conducted with 51 men and
women who had pattern alopecia showed a
significant reduction in the percentage of
telogen hairs along with stabilization of the
hair loss. Although more than 70 percent of a
topically applied preparation is metabolized to
weak non-androgenic by-products, the absorption
of topical estrogen can lead to decreased libido
in men.
Topical estrogens are not generally available in
North America, but they are being used in Europe
and topical estrogen products are available from
a number of pharmaceutical companies there.
There seems to be some confusion over which
estrogen formulation is best (as there are
different types of estrogen) but it seems that
estrogen application topically could help treat
pattern baldness in both men and women.
Progesterone for male
Progesterone is a
potential topical hormone for treating male
pattern baldness
Topical progesterone has been utilized widely,
but has not been thoroughly tested in clinical
studies. One study undertaken to ascertain the
efficacy of the compound used topical
progesterone (concentration and vehicle unnamed)
for 10 to 48 months in 12 men, in the age group
18 to 39 years, with male pattern baldness. None
of the subjects grew hair: 6 of them developed
further thinning, and the other 6 had the same
hair density.
Overall, topical progesterone has not been found
to be of great value in treating androgenetic
alopecia, but it can have a limited positive
effect for some people.
