Baby hair is falling out

Katherine • Mommy to a loving baby boy ❤️👶🏻 // NYC 🏙

So I have a 2 month old and his hair has slowly began to fall out and now he has a bald spot. Is this normal? It all happened because he had crattle cap and the doctors said to use Johnson’s baby lotion, mind you. I don’t use any Johnson products. This product made his hair fall out even quicker. I stopped using it a day ago. Any other recommendation to help hair from falling out ?
