he means you posted it in the wrong section it should be in the introduce myself section or the general hairloss section as you might get more replies there. (this section is for new discoveries and miracle cures of which there are very few indeed)
as far as your hair i am not sure, it does look thin but i am not an expert in your hair type (nappy if it is alright to say nappy?) so i am not sure how it looks under different lighting. normally nappy hair looks very thick and you can't really see the scalp but i think you have looser curls so it is not really "nappy". are your male relatives BALD?
the area i live in is 99% white so i am used to seeing straight and curly hair. myself my hair is (or was) as straight as a chinese mans hair
