Previous approaches were only marginally effective as they reached one set of hair cells in the inner ear, but another subset — equally critical for hearing — remained largely impenetrable.

The pairing of the two delivered the breakthrough solution, the researchers said, as neurons responded to the molecule, regenerating synapses in mouse ear tissue that led to repair of the hair cells and neurons, which are essential to hearing.

As a result, the sensory hair cell bundles that receive sound and signal the brain deteriorate and become disorganized, leading to profound hearing loss.

Scientists aren't sure if the neurons are triggered by the death of hair cells (which detect normal level sound as part of hearing) or simply dangerous sound levels.

Whether it is hair, skin cells, sweat or waste material such as urine and faeces, you are constantly shedding material that started off as part of you.

Still, by identifying the human hairless gene as an important master switch in regulating cell death in a hair follicle — a discovery that could lead to gene therapies for unwanted hair growth — Christiano emerged as a new star in the field, and a glamorous one.

Doctors diagnosed the problem as alopecia areata, a genetically determined autoimmune disease in which the body's T cells identify hair - follicle cells as foreign invaders and try to destroy them.
