I got three inches cut off my hair about four weeks ago. It was shoulder length and after I got it cut, it was to my neck. I started washing my hair twice a week. The kind I use is shampoo and conditioner in one. I also had my mom braid it. Now it's longer and really thick!! It's also even and healthy because all my split ends got cut and I wear a wig. My real hair is braided underneath. I also haven't flat ironed it since I got it cut. Now it's even!!
My hair doesn't grow abnormally fast but it grows at a steady rate. I've gone from armpit length to bra strap length twice, and both times took a little less than a year, which is a pretty standard rate of growth. Hoping to reach mid back in a few months.
I don't think my hair's ever been truly even, though. The back grows a lot faster than the front so I've always had what looks like face-framing layers in the front and longer hair in the back.
