Orange Peel Tincture: I know of at least 5 common plants that will cause hair to grow. I’m sure there are many more. If you want to verify scientifically that this orange peel tincture works, find a place (cosmetic boutique) that has a skin camera and you can see the hair follicles up close. Take a photo or a video of how many hairs are growing in a selected region of a balding area. Pick an area that still has some hair growth activity and is not totally bald. After one month of daily application of the orange peel tincture, look at the same balding area with the camera. You will see a significant amount of new hair growth. I’ve seen amazng results from people who tried this in Japan. Here's how you make it: Get a wide mouth one gallon jar, Peel enough oranges to fill the jar at least half full with orange peels (you can eat the oranges). Cover the orange peels with sake or vodka and allow to sit for at least 3 weeks. You then pour off the liquid into another bottle and discard the peels. Get a pump spayer type bottle and spray your balding area at least once a day after showering and preferably 4 or 5 times throughout the day. The liquid will make your hair somewhat stiff (yes, it's not a perfect world). The hair will only grow as long as you apply the spray. When you stop spraying, the growth activity stops. You can increase your chances of success by rinsing your head with a citrate spray when finishing your shower.
Hulda Clark mentions this in her book. It helps keep the hair mantle acid, which encourages hair growth.
