[Product Request] Dry/flaky beard.

Im 30 and ive had my beard for about 10years now. The last 3-5 years id say I could not stop getting white flakes to come out. I typically wear black and its pushing me enough to be self conscious.

Ive tried oils, balms, lotions and moisturizers and it feels nice for the moment. With daily use it doesnt help at all. I have a fine wood brush i use and i could brush for hours and get a pile up to a half inch of dandruff/skin and it keeps coming.

I have used straight argon oil, then tried jojoba and both have not had any success.

Anyone have this issue or managed to solve this for themselves? Next step i would guess is a dermatologist.
