Generally, you shouldn't be losing more hair when adding in a pre-shampoo to your routine! However, if you are experiencing increased hair fall, we recommend a few things: - double-check that you're using an oil friendly for your porosity type - detangle your hair prior to shampooing - avoid pre-shampoo on the scalp - lessen the overall amount of pre-shampoo used on your strands - Choose a lighter oil to use on your hair, or opt for a lighter pre-poo alternative like a humectant (if this suits the humidity levels where you live)
