Hair loss following rapid weight loss

I have been shedding hair like crazy during the last month. It may be from shock due to losing 10 lbs of weight but I don’t know how rapidly I lost the weight. I am eating less carbs and more protein though. If the hair loss is due to shock how do I reverse this? I don’t want to start eating loads and regain the weight. 

Rapid hair loss following a loss of rapid weight loss is common. If you have the genes for hair loss, then the hair loss induced by the weight loss may not be reversible in men.
