Hananke, in asking about your routine, I guess I was wondering, in those pics, did you blow-dry or diffuse or air-dry your hair? Do you leave some conditioner in your hair? Do you "plop"? That kind of thing.

You may be right, straight hair may look more professional in general. So maybe you'll have to use a blow-drier and round brush to "straighten" your hair for on-air days. Then experiment with curly stuff on your off days. The pic I posted the link to shows a reporter who has beautiful curls, and she looks very polished and professional. So it can be done! But it may take you some time to get there. Post more pics as your curly hair develops!
