Correct? Actually I live in Pakistan and here pharmacist are not so good so I will have to give them instructions.
Yes, most of the solutions are made using Ethanol, propylene glycol and water.
You can read the ingredient list of these topical lotions on the bottles or find the contents online. The alcohol percentage varies from one product to another but most have about 60% Ethanol , 20% Propylene Glycol, and 20 % water.
It is Propylene Glycol which cause most of the irritation from topical minoxidil use.
