Exercise helps every part of your body, including your hair. I don't think it will have any visible effect on it. It is probably good for it though as you increase your circulation and it might help the blood deliver more nutrients to your hair root, but again you won't see a drastic difference. 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.
Histologically, ganglioglioma is composed of both neoplastic glial and ganglion cells which are disorganized, variably cellular, and non-infiltrative. Occasionally, it may be challenging to differentiate ganglion cell tumors from an infiltrating glioma with entrapped neurons. The presence of neoplastic ganglion cells forming abnormal clusters, the presence of binucleation and dysmorphic neurons are helpful clues favoring ganglioglioma over glioma.
