Abstract

A power hairbrush which oscillates in operation with a frequency in the range of 55 Hz-120 Hz and an amplitude in the range of 8-20°, with a brushhead adapted to remove sebum and other material from the scalp and hair of a user, the brushhead including a plurality of lines or rows of filament tufts, wherein each filament in the filament tufts at its distal end is split into several portions. The brushhead further includes a plurality of lines of solid tuft members positioned adjacent to the lines of filament tufts. The filament tufts are approximately 1-3 mm taller than the solid tuft members.

First claim

What is claimed is:

1. A brushhead, comprising:
a brushhead structure removably fittable to a drive shaft of a handle for a hairbrush;
a plurality of lines or rows of spaced-apart filament tufts forming a portion of the brushhead structure, extending radially of the brushhead structure toward a peripheral edge of the brushhead structure; and
a plurality of lines or rows of spaced-apart looped structures extending radially of the brushhead structure toward a peripheral edge of the brushhead structure, wherein each line or row of filament tufts is bounded by lines or rows of looped structures, or wherein each row of looped structures is bounded by lines or rows of filaments tufts.

2. The brushhead of claim 1 , wherein the plurality of spaced-apart filament tufts and the plurality of spaced-apart looped structures are distributed on the face of the brushhead structure in regular geometric patterns.

3. The brushhead of claim 1 , wherein a number of spaced-apart filament tufts and a number of space-apart looped structures are distributed on the face of the brushhead structure ranges from about 13 to about 23 per square inch.

4. The brushed of claim 1 , wherein the height difference between the plurality of spaced-apart filament tufts and the plurality of space-apart looped structures ranges from about 1 mm to about 3 mm.

5. The brushhead of claim 1 , wherein each of the plurality of space-apart filament tufts includes a plurality of multi-tipped filaments.

6. A brushhead, comprising:
a brushhead structure removably fittable to a driveshaft of a handle of a hairbrush, comprising:
a plurality of lines or rows of spaced-apart filament tufts forming a portion of the brushhead structure, extending radially of the brushhead structure toward a peripheral edge of the brushhead structure; and
a plurality of lines or rows of spaced-apart looped structures extending radially of the brushhead structure toward a peripheral edge of the brushhead structure, each line or row of looped structures positioned adjacent a line or row of filaments tufts, defining pairs of filament tufts and looped structures, wherein the distance between each pair of filament tufts and looped structures and an adjacent pair of filament tufts and looped structures is greater than the distance between the filament tufts and the looped structures in each pair thereof.
