Hello, I've been trying to lose weight rapidly for a couple of months now. I would eat once a day or so and exercise like 3 times a week. I've been noticing that my hair is thinning and I'm getting getting a lot of pimples and rashes on my face. I also smoke wax which helps me sleep and not eat. I'm really worried about my hair loss and bad skin. I obviously know that I need to change my ways bit my question is.. is my hair loss fixable and do I have any damage?
