Frontal Fibrosing Alopecia as a result of medications
and supplements

Introduction
Frontal fibrosing alopecia (FFA) is a form of hair loss that
affects the frontal hairline at menopause in white female patients.
FFA is typically progressive and results in irreversible scarring
and alopecia [1]. There is no reliable treatment of FFA but
steroids, anti malarials and methotrexate have been tried [2].
The disease is considered progressive although there is a
subset whose disease slows over time, regardless of treatment.
We theorized that FFA is mediated by changes in local
tissue aromatase activity affected by the use of
medications and supplements in addition to the physiologic
effects of age, body habitus, and hormonal status.
Objectives
FFA typically affects white women almost exclusively in the
frontal hairline. The incidence of FFA is increasing [1]. The onset To collect biometric and pharmaceutical data in women with
FFA for known factors that would alter aromatase.
of FFA at menopause strongly implicates a hormonal effect
although the exact mechanism is unknown [3].
To examine the effects of drug and supplement reduction (in
Estrogen synthesis shifts from the gonad to peripheral fat tissue addition to diet and exercise) on FFA.
starting in middle age, peripheral estrogen production is
controlled by local transcription factors that regulate aromatase
activity[ [4,6]. Aromatase exhibits regional and gender
differences in the scalp, with women having a 6 fold increase in
aromatase in the frontal scalp [5,6].
Methods
Age, obesity, insulin resistance and drugs impact endocrine
signaling pathways and have the capacity to up regulate
aromatase [7]. Up regulation of aromatase leads to androgen
depletion and the formation of harmful estrogen metabolites that
affect fibroblasts and macrophages [5,8,9].
Data was collected on patients presenting to a private
dermatology practice with FFA from 2011 to 2014. We
collected biometric data, drug lists, including vitamins
and supplements, Fitzpatrick phototyping and comorbid
states.
In addition to diet and exercise recommendations,
vitamin and supplements were discontinued with the
exception of vitamin D. Whenever possible, drugs
known to increase insulin resistance were discontinued
or modified to improve the insulin resistance profile.
Response to therapy was defined as reduction in
redness and scale at the follicular os and no further
progression of alopecia. Patients were categorized as
responders or non-responders.
Results
• 18 patients presented with FFA during the study interval.
One patient was not accepting of therapy and one
patient did not follow up. The remaining 16 patients are
summarized in Table 1.
• 9/18 patients who had medications adjusted along with discontinuation
of vitamin and mineral supplements responded to therapy; 6 more
have agreed to our suggestions on reduction
• 1/2 patients who were not on medications known to affect insulin
resistance or on vitamins/supplements improved with increase in
vitamin D (pt 7)
• 1 has had relentless progression and no response to treatment (pt 2)

• 11/18 patients had a BMI greater than 25.
• 11/18 patients were taking drugs known to negatively
impact insulin resistance and increasing aromatase
(most commonly a statin drug and/or sertraline).
• 7/18 were on 5 or more supplements.
Frontal fibrosing alopecia results from an inflammatory attack on the
hair follicle in the frontal hairline in women at menopause. It occurs in
women of Northern European ancestry and appears to be increasing in
incidence [1,2].
We propose that women with FFA have difficulty navigating midlife
changes in peripheral estrogen metabolism. The up regulation in
aromatase may be physiologic and accompany age and menopause
[6]. These changes may also be magnified by medications and
supplements known to negatively affect insulin resistance and increase
aromatase [8]. Physicians caring for women with FFA should include
drug histories and drug stratification as part of their treatment plans.
The prolific use of vitamins and supplements found in this series
supports further investigation into the risks and benefits of this largely
unregulated industry.

• 15/18 patients were Fitzpatrick level I and II, consistent
with other studies showing a predominance in women of
Northern European ancestry.
The racial predominance seen in FFA implicates a genotypic
basis for the disease. Fitzpatrick phototyping is a clinical tool
for objectively assessing skin pigmentation which may also
be a potential biomarker of vitamin D status and genotypic
variation in the human aromatase complex.
Discussion
Pt 4-Baseline and one year after changing the statin from simvistatin to atorvastatin. The
patient also started metformin which lowers aromatase
