Brushing
Brushing.
The whole value of hair brushing depends on the increased blood supply induced by vigorous friction and the removal of the scurf or cast-off skin causing strangulation of the hair roots.
The hair, to be benefited to the utmost, needs to be steadily brushed from front to back all round the head with regular rhythmic movements, and only when the skin feels the effect of the brush and even tingles a little is the right effect obtained.
