You drink it and you could also spray a little on also.
Just drinking it is fine.
Also the shedding of hair is an indication that the body is a little low on nutrients.
Some good multivitamins should help also.

Something else very key to hair health is cleanliness of the liver.
Its the livers job to process nutrients, proteins etc. that come into the body.
If the liver isn't able to process these well, nutrients won't be getting into the body like they should.
A few good Liver Flushes can make a difference in hair health.
There probably isn't anybody walking around that couldn't benefit from a liver flush. Unless they have already done many.

And of course diet is key to hair health.
I wouldn't be surprised if the U.S. is the leader of the pack in the percentage of balding people walking around.
This would be due in great part to the Standard American Diet.
It clogs the liver and is practically devoid of nutrients.
Organic fruits and vegetables are not part of the S.A.D. diet.
