What Causes Hair Loss And Excessive Weight Gain?

Hello, I ve had my hair falling out for about 10 months now. Started exercising and over that time gained 10 lbs. I take bone broth, multi vitamins, Biotin, b complex, wheat grass juice. Tried essential oils such as ceder wood and rosemary on my scalp in coconut oils and aloes. Last 3 months I went on the keto diet. But only lost water weight and my hair loss kept on and now the hair on my legs is not growing in or under my arms. I just stopped drinking coffee this past week. I also have hypoglycemia symptoms my whole life. I always assumed I was bored line since it runs in my family. I get stressed easily. Very tired, I require about 9 hours of sleep every night.
