I'm struggling to figure out if I have a problem or not!
I have shoulder-length loose curls (2c-3a in pic below). I brush my hair before I wash it, which is either every day or every two days. I use product on my hair to avoid frizz. When I brush it lots comes out. Before washing my hair I brush until no more comes out, then when I'm in the shower lots more does. In the second photo there's what came out on the brush and then what is wet from the shower. There will be more in the drain because I have to unblock that regularly. I even use a lice comb periodically after brushing just to brush out more before I get into the shower, but there's always more in the shower.
I rarely wear black or dark colours because my shoulders end up covered in hair (as they do with lighter colours, but then it's less noticeable).
Is this a curly hair thing, or a me thing?
