when can i wash my hair after applying alcohol-free minoxidil serum?

You should continue to wash your hair according to any routine that works best for your scalp, and does not cause irritation or dryness. Over-washing the hair can be counterproductive, and should be avoided.

With alcohol-free Minoxidil Serum, you can apply this treatment either before or after you shower. If you are planning to apply the serum beforehand, it is recommended to wait at least one hour after applying before you shower, in order to allow the medication to fully absorb into the hair follicles. However, you can also apply it after you shower, to either a towel-dry or dry scalp.

As an example, one routine which may be convenient is to apply shortly after showering in the morning, to a towel-dry scalp, and then around 5-10 minutes before going to sleep at night.
