Big chop, straighten hair?

So I cut off all my hair and it looked like a high top — decided I was gonna start fresh from the heat damage I had.

That was in August and it’s April and it can go into a pony tail and it stretches out to my collarbone.

Anyways I’m so tempting to straighten it just this one time outta this entire year, should I?

I can’t get heat damage after one flat iron rt?
