Brush. Brush. Brush.
Brushing your hair boosts blood circulation in the scalp and ensures more efficient delivery of nutrients to the follicles. The healthier your follicles, the healthier your hair will appear. Start several inches from the hair ends, and work your way up the shaft, using fingers to gently detangle any knots along the way. However, when hair is wet, use a wide-toothed comb instead of a brush as hair is more fragile and will snap easily when force is applied.
