Hi
Hair loss in males is usually genetic and hence is called male pattern baldness. Increased hair loss is one of the symptoms. But best is to consult a doctor regarding the same because inadequate nutrition, scalp infections, smoking, helmet use , etc all would cause an increase in hair fall
Next Steps
Visit a doctor to rule out other causes of hair fall. Modify diet to include antioxidants and vitamins. Stop smoking. Wear a cotton cap under the helmet. If medical treatments don't work then could try out PRP injections. But if already have established hair fall then Hair transplant would be the option
Health Tips
Avoid smoking
