Maxima has one biggggg problem. She want's to be very blonde and contrary to what L'Oreal says, that takes a heavy toll on your hair. Add to it, that apparently she has had quite some hair loss over the years (post pregnancy hormone change??) and she just doesn't have any volume to speak of. IMO she should rethink her colour, go much less light and invest in some really good extensions (not length but volume wise). And yes chop it off at the shoulder.
I think one of the reason we only see her with styled hair on grand occasions and with seemingly unkempt hair on everyday duty is that she has been advised to leave her hair alone as much as possible so she prolly doesn't even blow dry it normally.
Dying her hair blond has destroyed Maxima's already thinning, weak, brown hair.
There does seem to be hair loss which means handling what is left with tender loving care, no blowdrying and tons of conditioning.
Perhaps something like this for Maxima in the future.
