Happy Head is a topical formula that comes in a liquid solution (not a gel), and each bottle is 60 mL, which lasts about a month. Our products are compounded monthly, so it is made fresh when you order it. This means that your bottle has not been sitting on the shelf for months. Our most popular topical solution consists of the following active ingredients: 0.3% Finasteride, 8% Minoxidil, 0.001% Retinoic Acid, and 1% Hydrocortisone. Happy Head offers a variety of products, and it’s important to note that all active ingredients are customizable.
