Postpartum hair fall

Going through the same problem. My hair is everywhere even on my baby's cot and it really made me frustrated. I have naturally thick hair and the amount of hairloss my god! I cut my hair short a mth ago and cut shorter yesterday. The hairdresser told me to treat the oil on my hair first and don't use 3in1 shampoo like Pantene, etc which has conditioner in it. I don't use any hair oil or conditioner but seems true to what she said and she recommended me an anti hair-loss shampoo made from Japan. Hoping to see good result soon!
