Hypothesis
Is Pseudo Alopecia Areata caused by metal pin fasteners in skull-caps?
Conclusion
Replacing the original pin with a different type and using a larger cupola effectively reduced the lesions in patients.
Supporting Evidence
- 33.3% of patients with two pins developed additional lesions.
- 58.8% of patients with a different pin showed immediate improvement.
- Conservative pharmacological treatments failed to repair lesions.
Takeaway
Some people lose hair because of the metal clips used to hold their skull-caps. Changing the clip and using a bigger cap can help their hair grow back.
Methodology
A prospective open label study with three non-pharmacological treatment methods for patients with scalp AA.
Potential Biases
Potential bias due to the small sample size and specific demographic.
Limitations
The study was limited to a specific religious group and may not be generalizable to other populations.
Participant Demographics
37 Jewish religious patients (34 males, 3 females) aged 22-52 years.
