Abstract
Background: Androgenetic Alopecia (AGA) is a non-
scarring alopecia that affects both males and females. It is
characterized by a progressive miniaturization of hair follicles
with a characteristic pattern distribution in genetically predis-
posed men and women. Topical finasteride is being investigated
as a new treatment for AGA with fewer side effects than oral
finasteride. Topical Spironolactone is the most commonly
used off-label anti-androgen for the treatment of AGA. In the
treatment of AGA, it acts by decreasing the production and
competitively blocking the androgen receptor in the target
tissue.
Aim of Study: The aim of this study was to evaluate the
role and compare the effect of topical finasteride and topical
spironolactone in the treatment of (AGA).
Patients and Methods: After meeting inclusion and ex-
clusion criteria and diagnosis of AGA was clinically established
by the characteristic distribution of frontal and vertex hair in
males and the Christmas tree pattern of diffuse hair loss at
middle hairline in females. It was dermosopically established
by the characteristic hair shaft thickness heterogeneity, peripilar
brown depressions (peripilar signs) and focal atrichia and also
folliscope established for hair density. Cases included in this
study had Norwad-Hamilton Scale types I to VII for men and
Ebling Scale types I to IV for women.
Result: Our study shows that a topical spironolactone is
better than topical finasteride in male and female group.
Conclusion: In this study, topical finasteride and topical
spironolactone are good options for management of androgenic
alopecia but topical spironolactone is better than topical
finasteride with few side effects when compared to oral
administration.
Key Words: Alopecia – Finasteride – Spironolactone.
Introduction
ANDROGENETIC Alopecia (AGA) is a slowly
progressive form of hair loss which begins after
the onset of puberty. It occurs due to underlying

susceptibility of hair follicles to androgenic mini-
aturization. It is the most common cause of hair
loss that affects up to 70% of men and 40% of
women at some point in their lifetime. Men typi-
cally present with hairline recession at the temples
and vertex balding while women present with
normally diffusely thin hair over the top of their
scalps [1] .
Topical Finasteride has been specifically for-
mulated to function by means of local application
to the scalp. It has been designed to significantly
reduce the body's direct exposure to the drug and
thus minimize any potentially adverse effects that
may arise from such exposure [2] .
Topically applied Spironolactone does not have
the same side effects as the orally ingested Aldac-
tone. In fact, the topically applied Spironolactone
works so well that it is often used as a one-two
punch combination with Propecia, it also decreases
testosterone production in the adrenal gland by
depleting microsomal cytochrome p450 and by
affecting the cytochrome p450-dependent enzyme
17a-hydroxylase and desmolase, as well as com-
petitive inhibitor of the androgen receptor blocking
the androgen action on the target tissues [3] .
Aim of the work:
The aim of this study was to evaluate the role
and compare the effect of topical finasteride and
topical spironolactone in the treatment of (AGA).
Patients and Methods
This is an interventional study was carried out
at the outpatient clinic of Dermatology, Venereology
and Andrology Department, Faculty of Medicine,
Zagazig University Hospitals in the period from
June 2018 till December 2018. Thirty two males

and females patients of different age, duration and
grades of AGA were be included in our study.
The diagnosis of AGA was clinically established
by the characteristic distribution of frontal and
vertex hair in males and the Christmas tree pattern
of diffuse hair loss at middle hairline in females.
It was dermosopically established by the charac-
teristic hair shaft thickness heterogeneity, peripilar
brown depressions (peripilar signs) and focal
atrichia and also folliscope established for hair
density. Cases included in this study had Norwad-
Hamilton Scale types I to VII for men and Ebling
Scale types I to IV for women.
Results
A total of 32 participants were enrolled in our
study included sixteen patients (8 males and 8
females) aged 20-60 years. They were treated with
topical finasteride solution 0.1% for six months
and sixteen patients (8 males and 8 females) aged
20-60 years. They were treated with topical
Spironolactone solution 5% for six months.

Discussion
The primary outcome of the study had to be
change in hair density and had to provide an effect
size such as mean and a measure of variance (stand-
ard deviation, standard error, or 95% confidence
interval). The age of the study group (males and
females) (33.7±6.4) ranged from (23 to 47) years
and (50.0%) of them were females and (50.0%)
were males. No statistically significant difference
in family history, side effects and patients satisfac-
tion between group using finasteride and spironol-
actone groups. In this study, the commonest Ham-
ilton Norwoods scale for males used finas-teride
baseline was grade III (50.0%) followed by grade
II (25.0%), grade IVa and V (12.5%) while com-
monest Hamilton Norwoods scale for males after
6 months was grade II (62.5%) followed by grade
III, IIa and IV (12.5%). In this study, the commonest
Hamilton Norwoods scale for males used Spironol-
actone baseline was grade II and V (25.0%) fol-
lowed by grade I, IIa, IV and VI and VI (12.5%)
while commonest Hamilton Norwoods scale for
males after 6 months was grade II and V (25.5%)
followed by grade III, IIa and IV (12.5%). No
significant statistically significant difference in
Ha-milton Norwoods scale baseline and after 6
months between male using finasteride and
spironolactone in this study, the commonest Ebling
scale for females used finasteride baseline was
grade II (50.0%) followed by grade III (25.0%)
while commonest Ebling scale for males after 6
months was grade I (50%) followed by grade II
(25%). In this study, the commonest Ebling scale
for females used Spironolactone baseline was grade
I and III (37.5%) followed by grade II and IV
(12.5%) while commonest Ebling scale for males
after 6 months was grade I (50%) followed by
grade II, (25.0%) no significant statistically signif-
icant difference in Ebling scale baseline and after
6 months between female using finasteride and
spironolactone. Our study shows that decrease in
signs of androgenic alopecia: (Hair diameter diver-
sity, peripilar sign and focal atricha), (100.0%) of
the male finasteide group had hair diameter diver-
sity baseline while (87.5%) had hair diameter
diversity after 6 months treatment. Regarding
perpilar sign, (100%) of the male group had perpilar
sign baseline and (75.0%) had perpilar sign after
6 months treatment. Concerning focal atricha,
(87.5%) of the female group had focal atricha
baseline while only (37.5%) had focal atricha after
6 months treatment. Our study shows that (100.0%)
of the male spironolactone group had hair diameter
diversity baseline while (100.0%) had hair diameter
diversity after 6 months treatment. Regarding
perpilar sign, (100.0%) of the male group had
perpilar sign baseline and (100.0%) had perpilar
sign after 6 months treatment. Concerning focal
atricha, (100.0%) of the female group had focal
atricha baseline while only (50.0%) had focal
atricha after 6months treatment. No significant
statistically significant difference in Trich-oscopy
data baseline and after 6 months between male
using finasteride and spironolactone. Our study
shows that (100.0%) of the female finasteide group
had hair diameter diversity baseline while (87.5%)
had hair diameter diversity after 6 months treatment.
Regarding perpilar sign, (100%) of the male group
had perpilar sign baseline and (62.5%) had perpilar
sign after 6 months treatment. Concerning focal
atricha, (87.5%) of the female group had focal
atricha baseline while only (25.0%) had focal
atricha after 6 months treatment. Our study shows
that (100.0%) of the female spironolactone group
had hair diameter diversity baseline while (100.0%)
had hair diameter diversity after 6 months treatment.
Regarding perpilar sign, (87.5%) of the male group
had perpilar sign baseline and (50.0%) had perpilar
sign after 6 months treatment. Concerning focal
atricha, (87.5%) of the female group had focal
atricha baseline while only (00.0%) had focal
atricha after 6months treatment. No significant
statistically significant difference in Trichoscopy
data baseline and after 6 months between female
using finasteride and spironolactone. (50.0%) of
the male group were satisfied, (6.2%) were very

satisfied and (43%) not satisfied after treatment.
In this study, the commonest Hamilton Norwoods
scale for males used finasteride and spironolactone
baseline was grade III (37.5%) followed by grade
II and V (18.8%) while commonest Hamilton Nor-
woods scale for males after 6 months was grade
II (43.8%) followed by grade IV and V (12.5%)
No significant statistically significant difference
in between Hamliton Noorwoods scale for male's
baseline and after 6 months using finasteride and
spironolactone. In this study, (100.0%) of the male
group had hair diameter diversity baseline while
(93.8%) had hair diameter diversity after 6 months
treatment. Regarding perpilar sign, all males
(100.0%) had perpilar sign baseline and (81.2%)
had perpilar sign after 6 months treatment. Con-
cerning focal atricha, (93.8%) of the male group
had focal atricha baseline while only (43.8%) had
focal atricha after 6 months treatment seventy five
percent of the female group were satisfied, twelve
and half percent were very satisfied and tweleve
and half percent not satisfied after treatment. In
the this study, Ebling scale (I-IV) of androgenic
alopecia for females: The commonest Ebling scale
for females baseline was grade II (43.8%) follo-
wed by grade IV (25.0%) while commonest Ebling
scale for females after 6 months was grade I
(50.0%) followed by grade II (25.0%) there was
statistically significant difference between Ebling
scale for females' baseline and after 6 months in
female patients. Our study shows that (100.0%) of
the female group had hair diameter diversity base-
line while (93.8%) had hair diameter diversity after
6 months treatment. Regarding perpilar sign,
(93.8%) of the female group had perpilar sign
baseline and (56.3%) had perpilar sign after 6
months treatment. Concerning focal atricha,
(87.5%) of the fe-male group had focal atricha
baseline while only (12.5%) had focal atricha after
6 months treatment.
In our study 68.7% of the male group had
increased hair count after 6 months treatment and
(87.5%) of the female group had increased hair
count after 6 months treatment. There was no
statistically significant difference between male
and female in percent of increased hair count after
treatment.
There was no statistically significant difference
between hair diameter diversity baseline and after
6 months in female patients. There was highly
statistically significant difference between focal
atricha baseline and after 6 months in female
patients. There was statistically significant differ-
ence between Perpilar sign baseline and after 6
months in female patients.
Our study shows that topical spironolactone is
better than topical finasteride in male and female
group.
Topical spironolactone and topical finasteride
in female group were better than topical spironol-
actone and topical finasteride in male group.
Result is in Mazzarella et al., 1997 for evaluat-
ing topical finasteride for pattern hair loss were
found, and only 1 study involved women. Finas-
teride 0.005% (in a base of ethanol, propylene
glycol, and water) was studied in 52 patients with
androgenetic alopecia, including 24 women (mean
age 33 years, range 23-38 years) in a 16-month
single-blind, placebo-controlled trial. Treatment
consisted of 1mL of solution applied twice daily
to balding areas. There was no response to treatment
in the first 3 months, however, by 6 months there
were statistically significant differences in hair
density and hair loss compared to placebo. Although
the results were not stratified by sex, by the end
of the study all treated patients had slight to marked
reduction of balding areas and all reported per-
ceived benefit, rating their treatment moderately
(27%) or highly effective (73%). Treatment was
well-tolerated.
With no report of local or systemic side effects,
and no effect on plasma testosterone or dihydrotes-
tosterone were observed [4] .
These results were in agreement with study
done by Charuwichitratana et al., 2003) using 0.1%
finasteride solution and also in agreement with
another study done by Sitticharoenchai, 2006).
Using 0.5% finasteride solution revealed superior
efficacy to placebo [5,6] .
Also a good response to topical finasteride was
confirmed a systematic seven articles were includ-
ed. In all studies, there was significant increase in
hair density and decrease in the rate of hair loss,
increase total and terminal hair counts, and positive
hair growth assessment with topical FNS. Both
scalp and plasma DHT significantly decreased with
application of topical FNS; no changes in serum
testosterone were noted. The authors concluded
that, preliminary results on the use of topical FNS
are limited, but safe and promising [7] .
A randomized, double-blind, comparative study
to determine the efficacy and safety of 3% minox-
idil versus combined 3% minoxidil/and 0.1% fin-
asteride in male pattern hair loss showed signifi-
cantly greater improvement in the 3% minoxidil/
and 0.1% finasteride group than the minoxidil
group [8] .

Moreover, application of 1ml once daily of
topical finasteride resulted in a more constant
response in terms of scalp DHT inhibition, than
the 1-mg of finasteride tablet administered once
daily, taking into consideration the possible inter-
subject variability derived from various factors,
such as the different grade of baldness [9] .
Spironolactone arrests hair loss progression
with a favourable long-term safety profile [10] .
Conclusion:
Based on the results obtained in the present
study, we can conclude topical spironolactone is
better than topical finasteride in the treatment of
androgenic alopecia in male and female group.
More studies with a large number of patients and
prolonged follow-up are needed to confirm this
and to compare the efficacy of topical finasteride
versus topical spironolactone in the management
of androgenic alopecia.
Topical finasteride and topical spironolactone
are good options for management of androgenic
alopecia with few side effects when compared to
oral administration.
