Im almost 16 now and ive been using creatine for about 3 weeks now and im losing a bit of hair is there anyway i can use it without losing any hair and can i get that hair back?

Creatine is not doing you any good, that you could not get from a balanced diet. It is unlikely to the cause of your hair loss. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!
