Results:
The study sample consisted of 346 (77.4%) females and 101 (22.6%) males. Regarding PMGH 257 (57.5%) people did not complain of PMGH and 190 (42.5%) people suffered from PMGH. Regarding gender, 160 (84.2%) females and 30 (15.8%) males had PMGH. The prevalence of PMGH in the present study was 42.5%.
Conclusion:
This study revealed that PMGH is a common trichological disorder. Most frequent associations to PMGH included thyroid, deficiency of vitamins, alopecia areata, vitiligo, smoking, sun exposure and personal habits like using hair straightener and application of hair gel. Family history of PMGH appears to play an important role in the predisposition of this disorder.
