Hello, Welcome to healthcare magic. from yourhistory, I understand that you got irritation and dandruff from Minokem-N solution and you are currently using plain Minoxidil solution. If you have not found significant improvement with minoxidil, you could ask your dermatologist about the option of adding on tablet finasteride 1 mg. This is another US-FDA approved drug for male pattern hair loss. This is a prescription drug and has to be used only under the supervision of a dermatologist. You could also try alternative topical preparations like peptides which are latest in the market. Have a healthy diet containing proteins, fruits and vegetables. Try to reduce stress by yoga/ meditation. Mineral water does not harm the hair. However, its benefits in hair loss is not proven either. Hard water can make the hair brittle and can cause hair shaft breakage. In such a case, mineral water may help. Hope this helps you. Take care.
