I'm using 1.5 ml/day and I only shampoo 2/3 times a week. I have really curly hair so it actually goes super frizzy on me when it's too clean. So what I'm saying is -- leave it on as long as you're comfortable as i don't think there is a too long. Overnight should be just fine I'd assume.
While I'h here -- I have that row of miniaturized hairs around my temple hairline that is so common. I swear they've grown a bit. I'm starting to believe that trinov will give regrowth. Also -- it's f*** tons better/easier to deal with than minoxidil. way way better.
