Summary
Female pattern hair loss (FPHL) is common, with many patients experiencing concurrent conditions like telogen effluvium, hypothyroidism, and low Vitamin D. A significant portion also had a family history of androgenetic alopecia.
Area of Science:
- Dermatology
- Trichology
Background:
- Female pattern hair loss (FPHL) affects many women, yet its causes and treatments are not fully understood.
- Current treatment guidelines for FPHL are not universally established.
Purpose of the Study:
- To investigate the clinical characteristics of FPHL.
- To analyze medical and family history, laboratory findings, and treatment adherence in FPHL patients.
Main Methods:
- Retrospective analysis of medical records from 210 FPHL patients.
- Data collected between January 2011 and December 2011.
Main Results:
- FPHL patients ranged from 8 to 86 years old.
- 85% had a family history of androgenetic alopecia.
- Common co-occurring conditions included hypothyroidism, hypertension, and telogen effluvium (TE).
- Vitamin D deficiency was prevalent (only 38% had normal levels).
- Elevated ferritin levels (>30 μg/L) were seen in 71%, and 85% had normal zinc levels.
- Treatment compliance was low, with 59% missing follow-up appointments.
Conclusions:
- Hypothyroidism, hypertension, and low Vitamin D levels are frequently observed in women with FPHL.
- Concurrent TE is common in FPHL patients.
- The study highlights the need for further research into FPHL pathophysiology and treatment.
