you have gorgeous hair... I THESE I SEE A LOT OF MANIPULATION SO THE IMAGE WOULD BE DISTORTING THE CURL PATTERN
but also u are right, possibly chemical on portions... next wash or even cowash can someone take a pic of your entire back of the head... no towel, no combing or brushing...or even drying
that may help u get the clearest picture
(any pics of like an afro puff?) a wash n go?
