If using Shampoo A has caused you to experience an increase in hair fall, it is a sign that you maybe sensitive or even allergic to one of the ingredients. This is why we always recommend to patch test any products or formulations before trying them out. While this shampoo formulation was created to be as universal as possible, you may need to tweak the ingredients to suit your hair and scalp. For example, it's possible that the olive oil in Shampoo A is not working for you. You can start by experimenting with different oils in the recipe to see which works best for you!
