could do good with some multivitamins but they dont really do anything tbh
MSG is definitely not something you would want regularly in your diet
a lot of factors come into play, genetics, hormones, etc
but tbh, its pretty natural. it'll grow back

yeah would do good
when using supplements, remember to take them at the right times with the combination of the right food and activities
or else you'll just end up wasting money with no progress
