Pressing only roots?

[collidoscope]

So I let my grandmother press my hair with a hotcomb a couple of days ago. The ends of my hair weren't getting real straight.. They're kinda puffy and curly. Right now my hair's like.. an illusion of a bigger fro and I'm loving it, especially since I really miss having longer hair. So my question is, if I get only my roots pressed, should I be expecting some sort of potential damage in the long run? I was hesitant to let her press my hair because I had read so much about heat damage.

Also, what is the best heat protectant out there for pressed hair?

I know this sounds rambly, but I'm really loving my bigger looking fro. Thanks so much in advance!
