This sounds like a much more serious problem that needs something other than a complexion lightener. Something is causing your hair to fall out and you to have dark circles under your eyes. You need to figure out what it is so that you can treat the problem from within. It seems to be like this is a classic example of something that is caused by stress or a difficult work schedule. Perhaps both. You need to find a way to reduce stress in your life and get AT LEAST eight hours of sleep per night. If you have trouble sleeping, then try a natural sleep aid like valerian. It does not leave you groggy in the morning and has lesser side effects. It delivers a natural and deep sleep.
You can also improve your body's ability to deal with stress by improving your diet. This means drinking plenty of water and eating whole foods with fresh fruits and vegetables. A good multivitamin and mineral supplement with also help immensely. Avoiding coffee, alcohol, and smoking will also help. So will avoiding sugary and fatty foods. It is important to take care of yourself at all times and especially when you are under stress.
