Brushing stimulates and encourage essential oils in the scalp to flow through the hair strands nourishing and protecting each hair, leaving it smooth and naturally shiny. Bristle strengths vary for fine or thick hair, and for best brushing performance it is important to use the right bristle strength. A bristle is similar to a hair in construction, and sections cut from nearer the root of the bristle are strongest and best for brushing thick hair, while sections from the tip or flag end are softer and more suited to fine hair and a delicate scalp.
