Background:
Alopecia areata (AA) is a common hair disorder of unknown etiology and prognosis with no definitive cure.
Aims And Objective:
(i) To study the efficacy and immunomodulatory action of 88% phenol on hair growth on test area in AA. (ii) To study various epidemiological factors in relation to AA.
Materials And Methods:
A total of 50 subjects presenting with nonscarring patchy hair loss on scalp were enrolled in this prospective open label study to receive 88% phenol at 3 weekly intervals in a tertiary care hospital. Efficacy was assessed using scoring system for density, pigmentation, and texture of growing hair.
Results:
Texture and pigmentation of hair growth was significantly improved at 9 week, while density of hair growth showed steady improvement, which was significant from 9 week onwards. About 78% of patients showed good to excellent response while none of them showed poor response.
Conclusion:
88% phenol was found to be efficacious with all patients showing hair regrowth. 88% phenol can be considered as a treatment of choice for stable AA due to its ease of application, easy availability, and low cost.

02:23Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
