Exercise helps every part of your body, including your hair. I don't think it will have any visible effect on it.

No, unfortunatley.
Gangliosidosis is a rare type of lipidosis, or lipid storage disorder, in which the lipids affected are the gangliosides. Lipid storage disorders are hereditary disorders in which harmful amounts of lipids, or fats, accumulate in body tissues and cells. Gangliosides are lipids located on the surface of cells.
Often referred to as ganglion cysts, ganglia are collections of thick fluid that collect into lesions that develop on or near a joint or tendon. Typically, most examples of ganglia develop on the wrist, although there are a number of cases reported on ankles and finger joints as well. In many cases, the presence of ganglia can create joint swelling that ranges from mildly irritating to very painful.
