Advice please ! What would happen if I didn't get my hair cut for a longish time?

[Rockaby]

I am trying to grow my hair and am wondering how long I can get away without having it cut?

I know everyone says you need regular trims, but do I really? I kind of resent paying lots of money fir a little trim and also when I ask them not to take my hair too short it usually ends up too short. As my hair is curly I think they underestimate how much they are taking off.

If I left my hair for say 6 months or longer what terrible thing might befall my cheveux please?

I have my hair cut every 6 months or so. I don't use hairdryers and have quite wavy hair. I use the curly girl method, and only 'wash' once a week. My hair has never looked better. Every time I go to the hairdresser my hair is frizzy for a couple of weeks, I'm better off not going. Next time, I shall ask them to just spray with water and trim it.
