Hair brush with movable bristles

A method of using a hair brush for multi-purpose hair styling and hair grooming, wherein the hair brush includes a brush housing having an outer stationary frame section having a plurality of stationary parallel sections each having short bristles thereon, an inner movable frame section having a plurality of movable parallel sections each having long bristles thereon, and a handle section attached to one end of the brush housing;

• the plurality of movable sections being interleaved with the plurality of stationary sections such that the movable sections are movable relative to the stationary sections;
• means for movably connecting the inner movable frame section to the outer stationary frame section;
• and means for repeatedly moving the inner movable frame section between a first position and a second position to reciprocate the inner movable frame section in a forward and reverse direction relative to the outer stationary frame section so that the long bristles operate to move the user's hair perpendicular relative to the direction of movement, comprising the steps of:
• a) moving said movable parallel sections to said first position for moving said short bristles relative to said long bristles for styling the user's hair by brushing the upper and lower layers of the user's hair rearwardly from the forehead in order to add more volume to the brushed hair of the user;
• and
• b) repeatedly moving said long bristles on said movable parallel sections from said first position to said second position for styling the user's hair by brushing the lower layer of the user's hair to the left and right in order to cover thin, balding or parted hair.
