In my personal opinion it shouldn't. I am not saying something went wrong when I say it shouldn't I mean that I wouldn't want it to. It is possible for it to turn out very thick. How long did you boil it for? Like I said amounts and boiling time also affects it...the longer it boils the thicker it gets. If it is really thick then the hair can end up flat and heavy. Yes try to get rid of the crunchiness with scrunching. But if your hair is really really stiff I don't know how much scrunching you might need.
