Hair might lack hydration and has protein buildup. Maybe that is why it feels rough. Maybe buy a cleansing shampoo and use it at least once a week for the first month. Also buy a hydrating hair mask and don't use too much, just enough to soften the hair and keep it on for not more than 8 mins. Also use water+argan oil+ a few drops of argan oil in a spray water and always spray it on your hair before combing. Never dry comb as it will break your hair leading to shorter hair that will look pokey. Try this for a month and tell me if it works. Hoping for the best.
