Have you changed something in your diet lately? If you are experiencing dull or limp hair, it's likely a result of your body not getting enough nutrients. You hair needs sufficient protein, iron, omega-3 fatty acids and zinc in order to be healthy, so a crash diet can deprive it of this.
"Very low-calorie diets are often lacking in sufficient nutrients and can stunt hair growth or leave hair dull and limp. If the nutritional deficiency is big enough — like for someone with an eating disorder — hair can fall out," according to WebMD.

If you have concerns about your health you should talk to your doctor.
