I have a big problem with having a dry scalp. It seemed to get worse when I had my locs installed. To keep my scalp moisturized I mix grapeseed oil and about 20 drops birch oil together in an applicator bottle and apply to my scalp about every other day. I started out using olive oil, either will do. The grapeseed oil or olive oil adds moisture and shine and the birch oil is effective in treating inflamed scalps.
