Hair colour packaging with comb
Over 50% of Japanese people of all ages colour their hair. Previously, hair colouring required experience and skill, so home colouring was not common. This is the first "squeezable delaminated bottle" with a comb for easy hair colouring. The bottle consists of two separate layers of resin. When the agent is dispensed, the inner pressure decreases and the inner layer is delaminated from the outer layer and forms a pouch inside the bottle. The pouch shrinks according to the amount of agent dispensed. The valve system on the comb prevents the air from entering the bottle, so the agent can be evenly dispensed to the last drop in any direction to achieve easy colouring of all hair, including the hard-to-colour front and back sections, just by combing.
