Rogaine Liquid when to wash the hair?

[Eezo]

Hi guys, I am new to this.

After applying the rogaine liquid when can I wash my hair?

The minimum amount of time I would wash after appling is 4 hours.

The Rogaine website states at least 4 hours...but I remember reading that for the Foam...probably the same for liquid..

You can find it somewhere on the Rogaine website.
