I have two little girls. If this happened to one of them, I would have her go natural.
Purchase a heat cap for her deep conditioning treatments, at Sally's it cost about $25-30. That way, she can carry it to who's ever house she goes to for her treatments, while you're away.
Buy a large stock of ALL the shampoos, conditioners, leave-ins, moisturizers, and oils that you would like her to use.
Write down a routine for someone to follow.
I agree with the braids that the other ladies have suggested. But the person she goes to needs to be gentle on her hairline, temples, and nape (because those are the most sensitive spots w/damaged hair). And make sure the braids are not too tight or heavy.
Also, I would not leave them in for 2 months...not at first. I would put them in for no more than 5-6 weeks at a time, do some intense protein and moisture DCs in between, and then put them back in again. Maybe even every month (4 wks) at first would even be better. Buy a light braid spray to maintain them and to keep her roots moist and clean (or maybe spritz them with plain water and some peppermint oil). Switch up the direction of the braids each time you put them in, so they do not put too much stress on the same strands and areas, over and over again.
Good luck. Keep us posted.
