“…It is important to note that the volunteers of Norwood-Hamilton types II, III, III vertex, IV, and V were enrolled in study and investigator analysis for frontal AA was also done but results were not mentioned [ 3 ]. Frontal AA is required to be discussed because of two reasons; firstly, AA can be reasonably treated if treatment will be availed during the early stage of progression [ 6 ]; therefore, effect of PSO on Norwood-Hamilton types II and III should be discussed in future studies. Secondly, in one of the studies comparing botanical treatment of AA (saw palmetto) and finasteride, it was observed that botanical treatment was not effective in treating frontal AA [ 7 ]; therefore, to ascertain the possibility of ineffectiveness or effectiveness of PSO on frontal AA, it is suggested to Cho et al to avail data relating the effect of PSO on frontal AA as it will clear the picture to some extent, though future studies are also desirable.…”
