J Gandhara Med Dent Sci Jan ;10(4):64-7.

OBJECTIVES: The study aimed to assess the effects of quarantine on non-scarring hair fall and to determine the relationship between sun exposure and hair fall. METHODOLOGY: This cross-sectional study was conducted in Karachi from January to June 2022. Ethical approval was taken from the institutional ethical review committee. Participants were recruited by non-probability convenience sampling technique after obtaining informed consent. Those with dermatologic diseases of the scalp (cicatricial alopecia, alopecia areata, seborrheic dermatitis, infections), high-stress levels, post-pregnancy, thyroid disorders, hormonal disorders and COVID-19 were excluded from the study. Hair loss was assessed using a self-filled questionnaire regarding the history of comorbidities, demographics, education, institute status during quarantine, hair fall experience and personal habits. RESULTS: The study consisted of 137 participants after exclusion criteria were applied. Among these, 95.6% complained of increased hair fall during quarantine. Most participants were women (63.4%) compared to men (36.6%). The average age of the hair fall group was 20 years. Only 15.3% of participants spent more than 1-2 hours in the sun, and the majority had their hair covered when going out during quarantine. CONCLUSION: Hair fall is high during quarantine, particularly among women of young age group. Personal habits and exposure to the sun for a short time at noon can affect hair fall in quarantine, although no direct correlation was found. Hair fall during lockdown is inversely related to certain comorbidities.
