If you’re looking for alternative ingredients, here are some suggestions. You can replace green tea with: *** Dry Chamomile flowers *** Peppermint - dry or fresh *** Rosemary - dry or fresh You'll want to brew these into hot water same as you would have done with green tea. If you use the dry leaves you can add 5g same as green tea, if you use the fresh plant, you can add around 15g of it as it's less concentrate than the dry leaves. These don’t have the exact same properties as green tea but they all have properties that are very beneficial for your scalp health. We can't wait to see how your homemade shampoo turns out!
