A hair removal device comprising: a. a handle; b. a head positioned on one end of the handle c. a collapsible reservoir suitable for containing a fluid to be dispensed during use of the hair removal device through one or more orifice(s); and d. an enclosure system comprising: a deformably rigid container enclosing the collapsible reservoir, a fluid outlet adapted to allow fluid to exit both the collapsible reservoir and the deformably rigid container; a first one-way valve adapted to allow air to enter but not exit the deformably rigid container; and a pressure applicator, adapted to pressurize air in the deformably rigid container, thereby collapsing the collapsible reservoir and causing fluid to be expelled through the fluid outlet; characterized in that said hair removal device has a pivot axis about which said head is mounted; and one or more orifice(s) in the skin-facing surface of the head are positioned at or close to the pivot axis; and wherein the device additionally comprises a second one-way valve disposed at fluid outlet, to allow fluid to exit but not enter the reservoir; and wherein the pressure applicator comprises one or more mono-stable buttons, whereby depressing a mono-stable button acts to pressurize the air by a defined amount to ensure that a dose of fluid is dispensed every time that the mono-stable button is depressed and releasing the mono-stable button causes it to return to its rest position and draw air through the first one-way valve into the deformably rigid container. a. a handle; b. a head positioned on one end of the handle c. a collapsible reservoir suitable for containing a fluid to be dispensed during use of the hair removal device through one or more orifice(s); and d. an enclosure system comprising: a deformably rigid container enclosing the collapsible reservoir, a fluid outlet adapted to allow fluid to exit both the collapsible reservoir and the deformably rigid container; a first one-way valve adapted to allow air to enter but not exit the deformably rigid container; and a pressure applicator, adapted to pressurize air in the deformably rigid container, thereby collapsing the collapsible reservoir and causing fluid to be expelled through the fluid outlet; characterized in that said hair removal device has a pivot axis about which said head is mounted; and one or more orifice(s) in the skin-facing surface of the head are positioned at or close to the pivot axis; and wherein the device additionally comprises a second one-way valve disposed at fluid outlet, to allow fluid to exit but not enter the reservoir; and a deformably rigid container enclosing the collapsible reservoir, a fluid outlet adapted to allow fluid to exit both the collapsible reservoir and the deformably rigid container; a first one-way valve adapted to allow air to enter but not exit the deformably rigid container; and a pressure applicator, adapted to pressurize air in the deformably rigid container, thereby collapsing the collapsible reservoir and causing fluid to be expelled through the fluid outlet; characterized in that said hair removal device has a pivot axis about which said head is mounted; and one or more orifice(s) in the skin-facing surface of the head are positioned at or close to the pivot axis; and wherein the device additionally comprises a second one-way valve disposed at fluid outlet, to allow fluid to exit but not enter the reservoir; and
