I noticed some hairs in my hairline are shorter than others. This appears to be the case only on left side of my head.
Is this thinning/minituarization on the pics? What are the chances it is going to progress further? Should I start finasteride?

We can’t tell you anything, it’s your hair and your hairline, maybe those hairs were there since forever, only you can tell. Compare photos of you from previous years and evaluate. If hair is important to you and you don’t want to risk it, take finasteride as a preventive medication and you will never have to worry about your hair again
Short answer: I don’t know
Long answer:Visit a trichologist or dermatologist AS SOON AS POSSIBLE even in the slightest hint of suspicion. They have special devices to look at your hair, even if minor miniaturization is detected it means you may go bald sometime into the future. Do NOT believe that nothing will happen. Do NOT underestimate the Norwood Reaper, he is a very, very sinister magician. I had done the same mistake with diffuse thinning, do NOT be like me. Maybe I will go bald, maybe not but I had lost lots of hair due to thinning etc. because I believed the situation has stabilized.
Do NOT also believe that balding will suit you or else. Bald as in the hair loss is not something good, unless it is voluntarily done (army shave or buzzcut, without hairloss.).
Also, recession of hair, while takes time and less aggressive usually also means that hair follicles go dormant starting from crown or frontal areas. In that case, minoxidil-fin/dut etc. type of medications will NOT work.
Your only hope then will be pp405, which is NOT yet available as of 2025, maybe never it will ever be available.
My current setup (like in hardware forums 
): 0.5mg dutasteride (avodart) +2.5mg oral minoxidil every day and ketoconazole (2%) twice a week. 1.25mg finasteride every day (for one month only, as a transitioning phase). For oral minoxidil blood pressure testing and for 5AR inhibiting drugs (finasteride/dutasteride) routine blood tests, liver and renal checks are HIGHLY recommended.
*Minor correction: miniaturization is not AGA-specific but if it miniaturization does progress over time, then it likely is indeed AGA. TE can resolve on its own, AGA in the absence of treatments cannot.
