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.
The signs and symptoms of the most severe form of GM1 gangliosidosis, called type I or the infantile form, usually become apparent by the age of 6 months. Infants with this form of the disorder typically appear normal until their development slows and muscles used for movement weaken.
