After wetting your hair, apply Node Fluid and lather by gently massaging the scalp. Rinse thoroughly with lukewarm water. Repeat the operation. The rinsing time should always be longer than the washing time. Let your hair dry naturally or, if you use a drier, make sure that the air is not too hot (excessive heat stimulates the secretion of sweat and sebum and makes the hair electric).
Node Fluid can be used as often as you need.
