Tweezing or plucking hair is best for smaller areas and can remove hair for 2 to 12 weeks. [27] Tweezing is inexpensive and causes minimal skin damage, but it also takes the most time and can cause pain in sensitive areas. [26] Laser hair removal uses red to near-infrared light (600-1100 nm) to remove hair.
Generally, many people lose hearing in their old age, especially high frequency hearing. This is caused by hair cell death, so it is hoped that techniques can be developed, such as by using stem cells or other genetic manipulations, to encourage the inner ear to regenerate its hair cells and restore hearing.
Cochlear hydrops preferentially affects the apex of the cochlea where low-frequency sounds are interpreted. Due to the fluid imbalance in this area, parts of the cochlea are stretched or under more tension than usual, which can lead to distortions of sound, changes in pitch perception, or hearing loss, all usually in the low frequencies.
For example, very curvy ear canals, narrow ear canals, or surgical ears are more prone to earwax buildup. When wax builds up, it causes muffled hearing, tinnitus, or aural fullness (plugged-up ...
Inner ear regeneration is the biological process by which the hair cells and supporting cells (i.e. Hensen's cells and Deiters cells) of the ear proliferate (cell proliferation) and regrow after hair cell injury. This process depends on communication between supporting cells and the brain.

For some, it's their hair, whether that be the length, texture, color or shine. On average, there are approximately 100,000 hair follicles on the human head. Despite this, hair loss happens to ...
Ear hair is the terminal hair arising from folliculary cartilage inside the external auditory meatus in humans. [1] In its broader sense, ear hair may also include the fine vellus hair covering much of the ear, particularly at the prominent parts of the anterior ear, or even the abnormal hair growth as seen in hypertrichosis and hirsutism .
