This is my hair fresh out of the shower, split up a bit, and then dried either while sleeping or air dried. I really like the waves that appear, especially in the second photo, but I don’t know if it means that I have wavy hair or not as my hair dries mostly straight! I tried a mousse, which didn’t work. Do you guys know what hair type I have, and how to naturally keep it as wavy/curly as possible? For reference, I am a natural brunette; I bleached my hair to white but it is still quite healthy and soft. I am in Boston, if the humidity matters.
