Can I use Minoxidil 10% every alternate day at night time? Will it be Beneficial?

This is difficult to answer without pictures and requires an in-person evaluation. I suggest seeing a hair loss expert to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

So most doctors recommend 5% Minoxidil twice/day but you think if you use a 10% solution you can take it every other day? IMO to get a constant blood level of Minoxidil, you should take it twice/day, every day for 4 months to ascertain if it works or not. If not, stop. You can take either concentration but bear in mind that Minoxidil does have uncomfortable side effects and the higher dosage presumably will have more side effects (dizziness, fatigue, palpitations, lower BP, skin irritation). You should apply it to a dry head 2 hours before bedtime. 

This concentration of minoxidil may not help you if you are a male with genetic balding and already have some bald areas
