Okay I need some help - I have been transitioning for a year my sister is all-natural . we both have a 4a and 4b mix. Once winter started , both of us our hair appeared to be shedding quite a bit . however our hair is not visibly thinning . mine is thick and past my shoulders, my sister's is super thick and growing into a lovely afro puff. Nevertheless when both of us see the shed hair we get concerned. we both shampoo with sulfate free and deep condition . is this just a phase ?? can anybody suggest anything or maybe know why it is happening??
