Yes. Happy Head is a CUSTOMIZED topical hair loss solution manufactured monthly just for you. This means that if you don’t want an ingredient in there, you can customize it. For example, if you are allergic to Minoxidil, you can request it to be taken out. If you are allergic to the Finasteride ingredient, you can remove it from the formula. You can request such changes during the checkout process. Although it is customizable, best results are seen when all of the ingredients are included in the formula, and our standard formula is the most common one written by our physicians, more than 95% of the time. It is typically recommended not to change the formula unless you are allergic to one of the active ingredients (Finasteride 0.3%, Minoxidil 8%, 0.1% Retinoic Acid and Hydrocortisone1%).
