Is it normal for your hair to straighten out when putting it in a ponytail/ bun?
My hair straightens when I put it in a ponytail/ bun. My hair is super thick but I'm unsure of my hair type.
I'd imagine if you has finer hair and/or a looser curl/wave pattern, it would be easy for your hair to straighten out while being pulled into a ponytail. Since you said your hair is thick, it might be the looser texture or the tightness of your ponytail. If it is the ponytail itself that is straightened, it might be the tugging done to your hair (which, I'd then reexamine whether you have thick hair or fine hair and a lot of it).
