This is a very interesting thread. I had a weave once in high school and it didn't last a week because of the itching. I've been relunctant to try it again because my scalp has to be shampooed on the regular and I didn't know how people cleansed their scalp and hair under a weave. I don't think I would ever do 4 months even if I could. That is way too long for me not to dentangle.
Transition your mind before you transition your hair.
