Beard thinning, head balding

Hey folks, this is my first time posting so i'm going to try and a get a few things in that have been troubling me for some time. I will list some symptoms (in order of concern) i have and then routes I am pursuing to address them. Not sure if they relate and am hoping for any insights.

1) starting after a return from 6 months in south america my beard has been turning white and the hair is getting thinner and weaker over the last 6 years. this started as small patches but has slowly covered my whole beard and is almost creeping in to my scalp!
2)as a 27 y/o male my head is balding pretty steadily.
3) my gums are receeding
4) sluggish digestion issues have plagued me for years.

to counteract these:
1) did a 3 month elimination diet. no sugars, starches, gluten, little dairy, lots of eggs and veggies.
2) did a parasite cleanse/enema round
3) using essential oils to stimulate my gums
4) started taking more multivitamins
5) used an antifungal cream on my fae for 1 week.

so far my beard is not changing and no notable hair return up top. i've kinda been hard on my body for the last decade (poor eating habits, at times little sleep, lots of stress and overworking) so i think its all taking an early toll.

I'm in a turn-around and am trying to do what i can to take care of myself now and would appreciate any help with the issues above. THANKS!
