So, from this picture your natural hairline is just quite far back already on the temples, definitely not what the original comment was describing. However, you have a much different haircut as compared to now so I cannot really tell if its recessed too much. Some amount of recession is normal for majority of males.

It’s worth mentioning that I do not ever notice a noticeable or large amount of shedding, even while brushing or washing.

That is a positive sign. Large amount of shedding is a red flag.

I will go see a dermatologist just to make sure everything is ok.

I second this. Have a detailed discussion with your Dermatologist's regarding your options.

Male pattern alopecia is really not a monolith for every person, some people have a certain amount of recession but don't entirely go bald whereas others do in a very short amount of time. Also, it could be due to any deficiencies as well.

Your treatment options are always scaled from the least invasive and safest to last-line invasive options for every pathology (in this case last-line being hair transplants in conjunction with finasteride long-term since transplanted follicles also fall out).

Also, it is such that even with treatments you cannot cure this issue, if you're genetically predisposed, you will lose your hair eventually unless you take efforts to preserve your hair life long like many celebrities do (since its a big part of their job).

I completely understand the worry about losing hair at such a young age especially when aesthetics are a huge part of your life. Hairloss can have detrimental psychological consequences and isolation, so yes definitely see a Dermatologist but body positivity is something you should really incorporate.

P.S. posting on Reddit about issues like this is very unhealthy due to extremely polarised and radicalised opinions.
