I feel like quitting alcohol and taking vitamin gummies/drinking more water is increasing my beard health

I'm a month and 15 days into a 12 month beard journey. I've been hairy since I started puberty (hair on my back, shoulders, etc.) I used to (imo) have a thicker beard that I took for granted until I started going bald.

I'm 15 days sober from alcohol and my beard seems to be looking better now than when I was drinking (I could be wrong though). I replaced my beers with water and started taking hair, skin and nails gummies (don't know if they're working though).

I've read that there is no proof that alcohol can cause beard loss, but I've also read that alcohol dehydrates you and affect vitamins from your body or something like that.
