would using theproduct twice a week help to speed up the result? should I continue to use the 2nd and 3rd boxes until my hair lost stops?

Bottom line: I would definitely continue with the next two boxes. And then take a break and see what happens. I am not really sure about twice a week, might be overkill.

You need to apply it once a week if you don’t wash your hair too often, otherwise twice a weekend. It’s a really good product.
