It's very normal. Just some people are worse than others!
Mine was awful. It started at 4 months, The front of my hair fell out. I can only put my hair up with a parting in a certain place do avoid stumpy bits sticking up. I pulled it out by the handful before i got in the shower, yet i'd still block the plughole every morning!
Angel is now 8 months and it's calmed down the passed month or 2. It's growing back slowly.
