Abstract: BACKGROUND: Hair loss is a common complaint among women and may be associated with psychological disturbances.
OBJECTIVES: This study investigated dermatology patients with respect to the prevalence of complaints of hair loss and the association between
these complaints and symptoms of depression.
METHODS: A cross-sectional study was conducted with female outpatients over 20 years of age with no hair-related disorders. Patients were
asked about hair loss and were evaluated with respect to symptoms of depression. The following variables were also analyzed: age, derma-
tological diagnosis, comorbidities, medications, family history of alopecia, hair length, the number of hairs extracted in the hair pull test and
the presence of hair thinning or seborrheic dermatitis. Data were compared by bivariate analysis and multiple logistic regressions between
groups of women with and without hair loss.
RESULTS: Of the 157 women interviewed, 54% reported hair loss and 29% reported at least two key symptoms of depression. The median
(IQD) age of the women was 51 (20) years. Complaints of hair loss were associated with the presence of symptoms of depression even fol-
lowing adjustment for the other covariates (p=0.02; OR=2.79; 95%CI: 1.18–6.61). Statistically significant differences were also found
between the patients with and without hair loss with respect to: age (p=0.03), family history of alopecia (p<0.01), hair length (p=0.01),
number of hairs extracted in the hair pull test (p=0.02), hair thinning (p<0.01), seborrheic dermatitis (p<0.01) and problems with person-
al relationships (p=0.04).
DISCUSSION: Hair-related disorders are a common topic of interest in this population. The significant association found between this com-
plaint and symptoms of depression indicates a relationship between the perception of hair loss and the psychological well being of the
women evaluated.
CONCLUSION: Complaints of hair loss were common and were associated with a greater prevalence of symptoms of depression among adult
female outpatients at a public dermatology clinic.

ÉTODOS: Estudo transversal com pacientes femininas, ambulatoriais, maiores de 20 anos de idade, sem doenças capilares. Foram questionadas
quanto à presença de queda de cabelos e avaliadas quanto à presença de sintomas depressivos. Também analisaram-se: idade, diagnóstico derma-
tológico, comorbidades, medicações, história familiar de alopecia, comprimento capilar, número de fios obtidos à tração e presença de rarefação
capilar ou dermatite seborreica. Os dados foram comparados bivariadamente e por regressão logística múltipla entre os grupos com e sem quei-
xa de queda capilar.
RESULTADOS: Das 157 mulheres entrevistadas, 54% referiam queda capilar e 29%, ao menos dois sintomas depressivos fundamentais. A idade media-
na foi 51+20 anos. A queixa de queda capilar esteve associada à presença de sintomas depressivos, mesmo quando ajustada pelas demais cova-
riáveis (p = 0,02; OR = 2,79 [IC 95%: 1,18-6,61]). Pacientes com e sem queixa também diferiram, significativamente, quanto à idade (p = 0,03),
à história familiar de alopecia (p < 0,01), ao comprimento capilar (p = 0,01), ao número de fios obtidos à tração (p = 0,02), à rarefação capilar
(p < 0,01), à dermatite seborreica (p < 0,01) e a problemas de relacionamento pessoal (p = 0,04).
DISCUSSÃO: Alterações capilares configuram tema de frequente interesse nessa população. A significativa associação dessa queixa com sintomas
depressivos indica relação entre a percepção da saúde capilar e o bem-estar psicológico das mulheres avaliadas. Conclusão: A queixa de queda
capilar foi frequente e esteve associada a maior prevalência de sintomas depressivos entre as pacientes adultas de ambulatório dermatológico
público.

Hair loss perception and symptoms of depression in female outpatients attending a general dermatology clinic 413
INTRODUCTION
Hair loss is a common complaint in clinical der-
matology, with this complaint also being common in
the adult population in general when these indivi-
duals are specifically asked about it.
1
On the other
hand, it is relatively common in dermatology clinics to
find patients with no apparent abnormalities at physi-
cal examination who complain of hair loss. This inco-
herency between the complaint and the findings upon
examination may have various origins.
Although women are genetically less suscepti-
ble to pronounced alopecia, they are more sensitive to
minor capillary abnormalities, possibly due to cultural
and behavioral factors.
2-5
Few studies in the literature have evaluated the
profile of hair loss as perceived by the patient from a
behavioral point of view. Likewise, the reliability of
this impression and its relationship with psychological
and clinical aspects has seldom been reported.
A better understanding of this perception and
of the possible variables associated with it in women
may improve the management of these patients and
lead to improvements in clinical dermatology with
respect to this disorder.
The present study investigated the prevalence
of a perception of hair loss by the patient when speci-
fically questioned on the subject and the variables
associated with this perception, particularly the pre-
sence of depression symptoms. The study was carried
out in adult patients attending a public dermatology
clinic.
METHODS
A prospective, cross-sectional study was con-
ducted between April and August 2010 with female
patients of 20 years of age or more, who had presen-
ted spontaneously at the outpatient dermatology cli-
nic of a public reference institution in Curitiba,
Paraná. Patients who were being treated for capillary
disorders were excluded from the study.
After their dermatological consultation,
patients were asked the following question: “Do you
have any problem with hair loss?” A positive or nega-
tive answer to this question was then used to separa-
te the women into a group of complainers and a
group of non-complainers, respectively.
The following data were obtained from eligible
patients: age, phototype, principal dermatological
diagnosis, comorbidities, medication used, family his-
tory of hair loss or alopecia, and awareness that the
dermatologist treats hair loss. Specific hair features
included actual and current hair type (straight, wavy
or curly), actual and current hair color (dark or fair),
number of shampoos per week, number of colorings
per month, length in centimeters of the hair starting
from the posterior vertex, and the number of times
the hair is combed per day. The patient was examined
for the presence of clinical signs of hirsutism, clinical
signs of active acne, seborrheic dermatitis of the scalp,
and hair thinning at the sagittal midline. Finally, the
number of hairs extracted at the hair pull test was
recorded.
The hair pull test was performed during the
interview by firmly securing a clump of hair between
the fingers and gently pulling it from the vertex region
of the scalp. No normal limit was established for this
test, since the data were evaluated as a continuous
variable.
The eligible women were also questioned with
respect to the symptoms listed below, based on the
International Classification of Diseases – 10
th
Edition
(ICD-10) depression diagnostic criteria.
6
The first
three are considered key symptoms.
Persistent sadness or low mood?
Loss of interest or pleasure in performing rou-
tine activities?
Fatigue or low energy?
Feelings of guilt or worthlessness?
Poor concentration or indecisiveness?
Disturbed sleep on a practically daily basis?
The women complaining of hair loss were
asked about the duration of the problem, the rela-
tionship between the seasons and the severity of the
problem and the way in which the problem was per-
ceived, from the following options:
From progressive thinning on the scalp
When combing hair
When taking a bath
From hair on the floor at home
From hair on the pillow
Other people noticed the problem.
The investigator’s subjective evaluation regar-
ding the presence of hair thinning at the vertex was
validated by standardized photographs of this region
of the scalp and by a count of the number of hairs
found over an area of 9 mm
2
in the first 61 patients. A
significant correlation was found between the number
of hairs and the investigator’s impression of hair thin-
ning (Spearman’s rho = 0.34; p<0.01). After this ini-
tial evaluation, only the subjective impression at sub-
sequent examinations was taken into account.
Categorical variables were represented as abso-
lute numbers and percentages, while continuous
variables were expressed as medians (interquartile
deviations [IQD]). Comparisons were made using
bivariate analysis between the group of women who
complained of hair loss and the non-complainer
group using the chi-square test, Fisher’s exact test,
William’s test or the Mann-Whitney U test.

Correlations were determined using Spearman’s rank
correlation coefficient and the normal distribution of
data was determined using the Shapiro-Wilk test. In
the multivariate analysis, abnormal distributions were
ranked.
The variables with a two-tailed p-value < 0.30
in the bivariate analyses were included in the condi-
tional multiple logistic regression. Next, the model
was reduced using a backward stepwise algorithm,
maintaining the variables with two-tailed p-values <
0.30 in the final model.
The minimum sample size was calculated at 156
individuals for a multiple logistic regression with a
power of 80% and alpha level of 0.05 to detect an anti-
cipated effect size of 0.15 and include up to 20 cova-
riates.
The coefficients of the categorical and logistic
associations were represented by the odds ratios (OR)
and their respective 95% confidence intervals
(95%CI). Two-tailed p-values < 0.05 were considered
statistically significant.
RESULTS
The study interviewed 157 women with a
median (IQD) age of 51 (20) years. The five most com-
mon dermatoses were melasma (11%), solar lentigo
or solar melanosis (11%), actinic keratosis (10%), acne
(6%) and onychomycosis (6%).
Following specific questioning, 54% of the
women reported having a problem with hair loss. The
way in which the problem was perceived was, in
decreasing order: while combing the hair (41%),
while in the bath (40%), from the amount of hair
found on the floor (27%) or on the pillow (20%), hair
thinning (12%) and from observations made by others
(6%). There was a significant association between the
physician’s perception and the patient’s perception of
the presence of hair thinning (OR = 22.83; 95%CI:
5.44 – 95.77; p<0.01; Fisher’s exact test).
The length of the hair correlated significantly
with age, shorter hair being associated with older
women (Spearman’s rho = -0.48; p<0.01).
Overall, 55% of the women interviewed did not
associate the treatment of hair loss with the dermato-
logist and there was no statistically significant diffe-
rence in age between those who were aware of the
scope of this specialist and those who were not
(median [IQD] age 48 [21] years versus 52.5 [22]
years; p = 0.18; Mann-Whitney).
The median (IQD) number of hairs obtained in
the hair pull test was 1 (2) (range 0-12) and was cor-
related with hair length (Spearman’s rho = 0.26;
p<0.01).
Seventeen patients (11%) had chronic diseases
related to hair loss, the most common being hypothy-
roidism (14 women). These 17 patients were the ones
in whom the most hairs were obtained in the hair pull
test (median [IQD] number of hairs 2 [1] versus 1 [2],
p = 0.02; Mann-Whitney test).
At least 22% of the patients were in regular use
of medication associated with hair loss, the most com-
mon being beta-blockers and antidepressants.
Of the women interviewed, 29% reported at
least two key symptoms of depression and 20% had
symptoms compatible with dysthymia.
The patients who complained of hair loss
reported that the problem had been present for a
median (IQD) duration of 12 (30) months, with a cor-
relation between the patient’s age at the time of the
interview and the duration of hair loss (Spearman’s
rho = 0.26; p = 0.02).
In the bivariate comparisons between the two
groups, the women complaining of hair loss were
more likely to have a family history of alopecia, longer
hair, seborrheic dermatitis, and more hairs removed in
the hair pull test. Additionally, the complainers were
more likely to have symptoms of depression and per-
sonal relationship problems compared to the women
who had not complained of hair loss (Table 1).
No differences in median age were found bet-
ween the group of women complaining of hair loss
and the group of non-complainers. However, when
sub-groups of age were analyzed, women of 20-39
years of age were more likely to complain of hair loss
than those of 40-59 years of age (OR = 2.55, 95%CI:
1.11 – 5.82; p = 0.02; chi-square test).
In the multivariate analysis, there were statisti-
cally significant differences between the group of
women that had complained of hair loss and the
group that had not with respect to age, knowledge
regarding the scope of the dermatologist, family histo-
ry of alopecia, the presence of hair thinning and the
presence of symptoms of depression (Table 2).
The association between hair loss and the pre-
sence of two or more key symptoms of depression
appeared to be restricted to the younger half of the
sample (Table 3).
DISCUSSION
In this culture, hair plays a very significant role
in gender identification and often acts as a fashion
item, a reference of beauty and style. Long, volumi-
nous hair is thus representative of health and youthful-
ness. Based on this, we have found that a perception
of hair loss may lead to feelings of loss of health and of
senility, generating significant psychological stress that,
in turn, may be associated with causing hair loss, the-
reby increasing the amount of telogen hair.
7
When questioned, more than half the women
interviewed reported problems with hair loss, which
An Bras Dermatol. 2012;87(3):412-7.
Hair loss perception and symptoms of depression in female outpatients attending a general dermatology clinic 415
was most often noticed during their regular hair-care
routine such as when washing or combing their hair.
Most of the patients were undergoing treatment for
mild skin disorders, some of which were almost enti-
rely cosmetic; therefore, there is a possibility that this
population may be more sensitive to hair-related pro-
blems than patients with more severe dermatological
disorders. It is important to emphasize that cosmetic
problems are currently routine in dermatology clinics
and it is important to recognize the profile of these
patients.
8
Surprisingly, the majority of these patients were
unaware that dermatologists treat hair loss and this
lack of information does not appear to be associated
specifically with older patients. This finding indicates
that, at least in the case of patients in the public
healthcare network, information should be provided
on the types of treatment available within the scope of
dermatology.
9
The presence of clinical conditions or the use of
drugs that could cause hair loss was rare in the
patients evaluated in this study. Nonetheless, more
hairs were obtained in the hair pull test in patients
with diseases associated with hair loss, the most com-
mon being hypothyroidism. It should be emphasized
that possible confounding factors related to this fin-
ding, such as whether these conditions were being
effectively treated at the time and the concomitant use
of other medications that could adversely affect the
hair, were not evaluated.
In the bivariate analyses, a significant associa-
tion was found between a complaint of hair loss and
the length of the hair or the number of hairs obtained
in the hair pull test. However, the multivariate analy-
sis failed to confirm these findings. This was probably
due to the significant correlation between these varia-
bles, as well as the significant correlation between hair
length and age, since only age was found to be inde-
pendently associated with hair loss in the final model.
These data show that the number of hairs obtained in
the hair pull test does not represent a good indepen-
dent predictor of the perception of hair loss by the
patient. On the other hand, the perception of hair
loss was independently associated with the presence
of hair thinning.
The above observations indicate that predefi-
ning an absolute normal limit for the hair pull test may
be difficult and that the length of the hair being tested
should be taken into consideration.
The multivariate analysis suggested that in the
age group evaluated, younger women are more likely
to complain of hair loss. Various factors may be asso-

ciated with this finding, including cultural and psy-
chological aspects typical of different generations or
of different age groups of women.

Since a considerable proportion of the patients
would be in the menopausal transition, principally
those in the younger half of the sample, the effect of
this phase of hormonal changes on the association
between a complaint of hair loss and younger age,
cannot be excluded. However, these data indicate that
the younger adults were more likely to complain of
hair loss than those in the age group associated with
the perimenopause, suggesting that factors related to
this complaint may be more significant at the begin-
ning of adulthood in these patients.
The data show a significant association between
symptoms of depression and a complaint of hair loss,
principally with respect to the patients in the third
and fourth decades of life.
In general, there is a greater prevalence of
mood disorders in outpatients compared to the healt-
hy population; nonetheless, few studies have evalua-
ted the association between these symptoms and hair
loss.
11
Since 38% of the patients who reported hair
loss had at least two of the three key symptoms of
depression, it is probable than many of these patients
would have benefitted from psychological evaluation,
which does not generally form part of the typical clini-
cal management of dermatology patients.
There are numerous factors related to hair loss
and to the perception of hair loss that may not be
completely coincidental. The apparently higher fre-
quency of this complaint among young adults toget-
her with the greater association of the complaint with
symptoms of depression and with relationship pro-
blems suggest a close association between this per-
ception and the psychological well being of these
women.
9
The above-mentioned association was not
found among the patients over 50 years of age, possi-
bly because there are more comorbidities and condi-
tions that trigger symptoms of depression in this age
group, as well as a proven increase in the prevalence
of depression and organic cerebral syndrome, which
may present in a similar form in the elderly popula-
tion in general.
12
The present study does not permit causal rela-
tionships to be established between the perception of
hair loss and the presence of symptoms of depression.
Furthermore, the presence of uninvestigated under-
lying conditions that could be acting on a possible
hair loss and on the patient’s mood cannot be discar-
ded. However, they were not the objectives of the
present study.
Nonetheless, mood changes cannot be elimina-
ted as causes of hair loss. Some molecular studies and
studies in animal models have shown that psychologi-

CONCLUSIONS
In the region in which this study was conduc-
ted, hair loss was present in a large percentage of the
adult female patients attending a public dermatology
clinic, even when this complaint was not the reason
for the patient to seek consultation at the clinic.
The most common ways in which the problem
was perceived by the patient were when combing the
hair or when bathing. Half the patients did not asso-
ciate the treatment of hair loss with dermatologists,
suggesting a need to inform the public on the scope
within this specialty.
Finally, the perception of hair loss was found to
be independently associated with a greater prevalence
of symptoms of depression, principally in adult
women up to the fifth decade of life. However, furt-
her studies with larger sample sizes and specific
designs should be conducted to define the association
between these observations. ❑
