After cleaning and rinsing your brush, wrap it in paper (construction or kraft paper is preferred but paper towels will work). Wrapping your brush is how to retain the shape of the brush and prevents fraying. Also it is important to allow your brush to completely dry between uses and always comb your fingers firmly through the bristles to remove any loose hairs. It is normal for your brush to shed a bit before/during your first use and subsequently fewer bristles.
