My baby it's 18 weeks old and she is having continous and heavy hair fall from last 2 months. Its like in particular area they is no hair left i.e in the back of her head . It getting red in that area. We use coconut oil for her hair but i don't think it's working well. We do not use cap or head ban for her hair but the problem still persist. We make sure that her hairs are clean so we clean it every two to three days. There is mere hair fall in front part of her head. Please suggest what to do. Your suggestion will be of great help.
