It'd probably depend on the type of hat, because I was always wearing a hat on my first 2 sets of dreads. I haven't wore one since I restarted them,and it feels great not to wear them anymore. I always wore the beanie visor knitted hats,and that definitely caused a lot of mashing because it's rather tight and what not.Thanks again for your reply. I have more hope now.
