The Baggy method takes its name from the English word "bag".

The principle is to wrap the hair, previously coated with care products, to optimize the active ingredients applied.
It is therefore advisable to apply a treatment to the hair: oil bath, mask, cataplasm... then cover it with a heating cap, a shower cap or a plastic bag or cellophane film.

The plastic material will retain the heat naturally released by the scalp, like a greenhouse, and thus open the scales of the hair and optimize the penetration of the active ingredients of the care..

For maximum effectiveness, leave on for at least 1 hour.
