A 60-second hair count is a reliable method to assess hair shedding in men. This study established normal shedding ranges for different age groups, showing consistent results over time.

Area of Science:

Dermatology
Trichology

Background:

Hair shedding is a common concern for men.
Establishing normal hair shedding ranges is crucial for accurate diagnosis.

Purpose of the Study:

To define the normal range for a standardized 60-second hair count in men without alopecia.
To assess the reliability and practicality of this method.

Main Methods:

A convenience sample of 60 healthy men aged 20-60 years without alopecia was recruited.
A standardized 60-second hair count was performed.
Hair counts were repeated to assess intrapatient variability and over a 6-month period.

Main Results:

The shedding range for men aged 20-40 was 0-78 hairs (mean 10.2).

The shedding range for men aged 41-60 was 0-43 hairs (mean 10.3).

Low intrapatient variability and stability over 6 months were observed, with consistent results verified by an investigator.

Conclusions:

A 60-second hair count is a simple, practical, and reliable tool for assessing hair shedding.
This method can aid in the diagnosis and monitoring of hair loss conditions in men.
