What deficiency could be causing diffuse thinning?

Male 17 NW2 Here, I've never been on this site so excuse me if this is the wrong chat to be asking this. I've been experiencing large amounts of shedding since about April, hair fall is present all around the head but mostly around the temples. My hairline has receded slightly and has gotten much thinner. Here is some blood work I got done 2 months ago, I'm not very familiar with what deficiencies can cause shedding/hair loss so any advice would help. Thank you

Something to be aware of which may or may not be relative, but many individuals are reporting excessive shedding (TE/telogen effluvium) post Covid infection due to the attack on their immune system.
There are many studies that have now been published, so if you may have contracted Covid at some time in the previous months to noticing shedding, this may have an influence.

Have you compared your blood work to what is considered normal? If you post a photo it will help get a better understanding.
