can your hair grow with braids???

[happylocks]

I have just done yarn braids they have been in for less than a week and I want to keep them in for 3 months, I am not sure how to care for them but I plan to keep my scalp clean with seabreeze. The braids are midback lenght and they do look like locs. I dont think they are too tight, altought my goal was to get them tigth doing them myself made that hard.
