I have medium- thick relaxed hair and i really want to grow it out to bsl by september?

im currently 6 weeks post relaxer and not relaxing for another 4 months .I have curly roots and straight ends oily at the scalp yet dryness and breakage on my ends i would like to stop this and restore moisture back into my hair . I deep condition weekly and oil my scalp with DooGro growth oil every other day im also planning on putting a weave in my hair as an protective style . I would love more info on how to take care of the braids under the weave
