Can I use vitamins to stop 22 year old male hair loss?

Vitamins would not be able to cure male pattern baldness by
regrowing your hair.

MPB is caused by your genetics. Your DNA basically codes for
the creation of hair receptors which are sensitive to the DHT in your body.
This causes them to shrink.

However, it is possible to slow down the rate of hair loss
through environmental factors. This would include healthy lifestyle habits such
as eating a well rounded diet, sun protection for your scalp, lowering your
intake of nicotine and alcohol as much as possible, exercise etc. A healthy
inner environment can help make your follicles more resilient.

You may also want to consider using Minoxidil which can also
help control the extent of hair loss.
Seek the help of a physician to best guide you through your hair
restoration efforts. 

For male balding, vitamins have very little if any role. You get adequate nutrients from your diet. You can consider minoxidil, finasteride and laser hair therapy and hair restoration down the road.
