Q: If I fix my diet and take vitamins, do I still need clinic treatments like GFC? A: It depends on the cause of your hair loss. If your hair fall is purely from a poor diet or low vitamins, correcting your nutrition will fix it. However, if your hair thinning is caused by genetics or hormones (like pattern baldness), vitamins alone cannot stop it. You need clinical treatments like GFC or Exosomes to actively protect the hair roots from hormonal damage and force them to grow.
