I've been losing beard hair since 2020. At first I thought it was normal as I keep my beard long.. I lose like 30-50 beard hair daily on average.. At first I thought it could be because of the dry skin underneath.. so i tried using oils like jojoba and almond.. but that never really cured my condition.. I also applied face  moisturizer to hydrate.. But the only mistake I made was that I let these oil and moisturizer sit on my skin for too long.. Like once I apply the oil or moisturizer at night, before bed, I don't wash it off the next morning, rather I let it sit on for more than 20 hrs, and then wash it off by evening. I don't know if that made my beard fall even more.🥲 Now, I'm losing beard hair specially from my moustache area. and it has visibility become lighter.. and the skin underneath is also visible and patchy.. I'm so worried now. I don't know what could be the reason.. do I need to follow an alternate skin care or should I do blood test to look for internal reasons?
