Aims and Objective: 1) To study the efficacy of topical minoxidil 5% in treatment of androgenetic alopecia. 2) To study the efficacy of combination of topical minoxidil 5%, topical azelaic acid 1.5% and topical tretinoin 0.01% in treatment of androgenetic alopecia. 3) To compare the efficacy of foresaid topical preparation in treatment of androgenetic alopecia Setting: Outpatient department of Dermatology, Venerology Leprology of a tertiary health care centre with an attached medical college. Material and methods: Topical minoxidil 5 % lotion was used in 23 (50%) patients of the present study. Combination of topical minoxidil 5%, azelaic acid 1.5 % and tretinoin 0.01 % lotion was used in 23 (50 %) patients of the present study. Statistical analysis used: Epi info version 7. Results: There was statistically significant increase in hair number and thickness after treatment in both the groups. The comparison of the increase of hair number and thickness was statistically insignificant. Conclusions: Topical Minoxidil 5% is equally effective to combination of topical Minoxidil 5%, azelaic acid 1.5% and tretinoin 0.01% in treatment of androgenetic alopecia.
