What are the differences between hair replacement and a hair transplant?

Same Thing: Hair replacement and transplantation are really talking about the same thing. This procedure involves taking viable growing scalp hairs from the back of the scalp and splicing them out into individual hair units (1-5 hairs per unit) and transplanting or grafting them into the thin or bald area on the front and sides of the scalp. It is very effective. See someone for "micrograft transplants".

Hair replacement: Hair transplant is a type of hair replacement which involves transplantation of hair from the back of the head to the area of hair loss. The hair from the back regions of the head are genetically designed to remain in place despite hormonal changes. Transplantation can be completed by strip or by [fue] follicular unit extraction. Transplantation is completed most naturally as single hairs.

The same: Both are describing the same procedure, where healthy hair is moved to an area of hairloss.
