B. Informed. Professional tips:
By simply placing the appropriate sized sleeve to a brush head after each wash, you can ensure that your brush will maintain its shape hence prolonging its use.
Ensure that all excess water is removed from the makeup brush once rinsed.
Shape the brush head, and simply apply the appropriate sized sleeve to the makeup brush. Allow to dry horizontally.
Sleeves can be removed once the makeup brush is dry.
Alternatively, the sleeve can be left on the makeup brush in order to maintain its shape whilst in storage.
