How are outer hair cells damaged?

“Factors such as loud noise and certain drugs, including antibiotics, can easily damage these cells, which can in turn lead to poorer hearing. Figuring out their exact role could help guide efforts to prevent or even cure common forms of hearing loss.”

Can Stereocilia be repaired?

Intense noise exposure damages the stereocilia F-actin core, which may be repaired by localized F-actin remodeling. Ribbon synapse loss, which can reduce hearing ability in noisy environments, may or may not be reversible.

What are the symptoms of cochlear damage?

Symptoms may include:

• Some sounds seem overly loud in one ear.
• You have problems following conversations when two or more people are talking.
• You have problems hearing in noisy areas.
• It is easier to hear men’s voices than women’s voices.
• It is hard to tell high-pitched sounds (such as “s” or “th”) from one another.

How does lack of blood flow affect hair growth?

In turn, the less blood supply there is, the slower hair growth as with the absence of adequate blood flow, nutrients – whether applied topically or consumed as part of supplements or balanced nutrition – never reach the hair follicle. This “starves” the hair root from much needed fuel even further. If it does sound like a downward spiral – it is.

How are blood vessels formed in hair loss?

Vascular endothelial growth factor (VEGF) is a signal protein produced by cells that stimulates the formation of blood vessels. “…people with hair loss may have fewer blood vessels.

What happens when you lose an outer hair cell?

Loss of outer hair cells produces a loss of sensitivity and frequency discrimination. In 1978, Kemp reported that brief clicks directed to the ear resulted in faint sounds coming out of the ear. These are called evoked otoacoustic emissions.

Can a breakdown in the immune system cause hair loss?

The result is that it starts to attack itself. This breakdown in the immune system can result in a wide range of symptoms, including hair loss. It is of course important that you don’t immediately assume that you must have an auto-immune disease if you start to experience unexpected hair loss.
