I have been experiencing significant hair loss mainly in the crown area and the M-shaped hairline (temples). The hair at the crown has become noticeably thinner, and my hairline has receded over the past few months. The hair fall is progressive, and I'm concerned it may be male pattern hair loss. I previously used a topical minoxidil + finasteride solution for about 2–3 months, and my hair improved. However, after stopping it for 1–2 months, the hair fall returned quickly. I would like to know the cause and the best long-term treatment with the fewest side effects.

I have been using 10% minoxidil and 0.1% finisteride for 2.5 years. It causes brain fog, lightheadedness and affects cognitive ability. I shifted to 10% minoxidil without finestride based on the doctor's suggestions and felt better. But the issue is still not resolved completely. This issue increases specifically during summer
