Most folks could care less about what type of hairbrush they use. However, choosing the right brush can promote healthier hair.
Boar bristle brushes are more densely packed so that the bristles can grab hold of sebum (the oil your scalp naturally produces), and spread it down the length of the hair shaft. This process creates more evenly moisturized hair and scalp, and also add a greater natural shine.
This type of stimulation and distribution of sebum has been found to promote healthier hair growth!
