Since the scalp is weak summer or with solid, winter is out with or dry, but had been using, for example, lotion and hair tonic for the scalp effect is not good enough. This is an appropriate amount (a little darker position) unexpectedly tone feel good of scalp If you try to use diluted to have. Scalp I also easy to get smell and weak It looks like it has also been suppressed, diluted quite profitable, since it allows people. It is also no side effects I think to try to continue to use.
