Suggest Remedy For Itchy And Oily Scalp Along With Hair Fall

Hello Doctor, I m suffering from hairloss for almost 6 years now, i lost lot of hair at my temples and the density has gone down, its been in this state for 3 years now not much change and no hairfall. I visited a dermatologist recently who suggested i go for PRP as i was at stage 3 hairloss, i was suggested 10 sittings at 15 day intervals and mintop 10, xtraglo, androanagen in combination. Sir, can you please let me know if the interval between PRP sittings is fine. I have a very oily scalp and it turns itchy if not washed daily so was suggested to use salisia xt. Thank You
