IF it's a piece of raw hide (not tanned) you might be able to get the hair off by soaking it in water until its flexible, then a few days in a solution of slaked lime and water. What has to happen is the upper layer of the epidermis containing the hair follicles has to decompose to the point that you can lay the skin across a board and "push" the hair and outermost layer of skin cells off the hide. Most folks do this while the hide is green (before being dried). NOT a process for indoors...
After you get your hide de-haired, rinse it out well in clear water, and either proceed with tanning or tack it on a frame to dry back into raw hide.
