Cold Weather (Air-conditioning included) and African / Black people type hair is not the best fit ever. Cold weather dries the hair and because this hair texture is already on the dryer side, being drier makes it brittle and so greater hair loss. In extreme weather conditions where a woolen cap or hat is necessary, make sure you first secure your hair with a satin or silk cover/scarf beforehand as the wool will create more friction and too much absorption. This also means that you MUST practice the NO COMBING technique after the day of shampoo if you do not like to see all those broken pieces in the sink and on the floor. Make sure you are using your OXX maintenance products to put well-needed moisture in the hair shaft.
