I'll just say off the bat that I don't generally hair type. There are far more relevant factors to take into account than curl pattern. But for argument's sake, I'm going to say I'm 4C.
When I first went natural, I really didn't understand hair typing so I just followed the popular bloggers, specifically, Naptural85 and Kimmaytube (Newbies be like 'who?'). And I believed that my hair could do the same things theirs could. Well. I was wrong. Not only couldn't it, it didn't even want to try. (I still cringe at my attempts at shingling). It finally twigged that my hair was totally different and that I had to find someone with the same texture as mine before I committed haircide and went back to the crack.
Cue massive stumbling block. I couldn't find anyone. These days, there are a few kicking about but back then, it was tumbleweed as far as 4C bloggers went. I did find those who sorta-kinda-looked-like-mine but they still had curls. Or rather coils.
And my hair doesn't. It doesn't curl or coil or clump.It's edges won't be laid and it can't wash and go. In fact, it's pretty much like having a stroppy teenager growing out of your head. It just wants to be left alone. *slams door* If I do try to force it, it punishes me by matting and tangling and knotting and drying up. My 4C hair may look tough as nails but is very fragile. To make it even more challenging, my strands are fine, therefore lots of handling = lots of breakage. So I learned that, in order to keep it happy and make my life easier, I needed to severely minimise how much I handled it.
