Studysummary In this hospital-based observational study involving 30 participants, researchers found no statistically significant difference in the force needed to pluck anagen versus telogen hair in the frontal and occipital scalp regions of women with female pattern hair loss.

Our plain-language summary. Not medical advice or a treatment recommendation. Consult a qualified healthcare professional before changing treatment. Full disclaimer

The study aimed to measure the epilation force required to pluck anagen and telogen hairs from the frontal and occipital regions in cases of female pattern hair loss using a trichotillometer. Conducted on 30 female patients over 20 years old with class 2 female pattern hair loss, the study found that the mean force required to pluck anagen and telogen hairs in the frontal region was 0.51N and 0.71N, respectively, and 0.61N and 0.51N in the occipital region. However, these differences were not statistically significant. The study concluded that the trichotillometer is a simple and effective tool for diagnosing pattern hair loss and assessing treatment effectiveness in an outpatient setting.
