Abstract

Objective: To compare mean hair density in healthy adult versus androgenic alopecia patient’s scalp in male Pakistani population

Study Design: Comparative Cross Sectional Study

Place and Duration of Study: Combined Military Hospital, Jhelum, Pakistan at the Department of Dermatology from Jul 2020 to Jan 2021.

Methodology: A sample size of 80 participants was calculated using WHO calculator. Participants were divided into two Groups i.e. Cases of androgenic alopecia and Controls, individuals without hair loss. Cases were defined as patients diagnosed with androgenic alopecia. We measured hair density by manual hair counting method.

Results: Total 80 males were included in study (40 males in each Group). Mean age of participants in Group A (Controls) was 36.8±5.74 and 36.9±5.31 in Group B (AGA). Hair density of one hair follicular unit in normal person at frontal and parietal region was 73.10+5.05 and 63.85+3.40 respectively while in AGA Group at frontal region it was 34.80+1.80 and at parietal region it was 45.10+2.20. Overall hair density was 160.25+16.36 in normal population and 98.75 +8.74 in AGA Group (p=0.02).

Conclusion: Average density of hair and hair loss patterns are variable for different ethnic populations. Hair densities in Pakistani population vary at different scalp site, however, occipital site showed the highest hair density. Hair density decreases with increasing age in Pakistani adult males. We suggest that simple hair counting using 1x1 stamp is effective in counting hair roots in resource limited hospitals and clinics.
