Started 1 part rosemary oil 4 parts pumpkin seed oil on scalp due to minoxidil causing dryness... would definitely recommend this, saw big drop in shedding and scalp health. Now i use minoxidil once per day as well as the oil.

I dont know any other top quality sources but whats worked for me is just the highly rated amazon essential oil for rosemary, as well as pumpkin oil. They seem to be working well for me so far
