TL;DR: You are norwood 3, the time to act is precisely right now.
1) I heard that the hair is very important and seen as a masculine trait in India and I assume you are an Indian judging from your skin color. Now, if both of these assumptions are true that the importance of hair in India and you being an Indian, you should fight AGA (aka MPB) nevertheless, whether you accept it or hate it whatever.
2)All hair loss treatments in the context of androgenetic alopecia (aka MPB for men), that is hair lost due to inherited sensitivity to a byproduct of testosterone, known as DHT, is chronic and for life. Yes, you have to take finasteride and minoxidil for life. Now, finasteride is to stop further loss while minoxidil is to regrow.
3)No, there is absolutely zero chance that you got your genes from your uncle or whatever. The problem is, irrelevant of where you got your genes, you are losing your hair in the framework of the traditional norwood-hamilton model in which areas sensitive to DHT gradually miniaturize and no further terminal hair grows from those regions. Or in layman’s terms, you are balding. This is the red pill, as in the matrix, that you have to take. If you don’t, you will go bald. You, I repeat again are balding. Remember the bald men you have seen when you were a child, men who with no hair at a time when you had a full head of hair, those men’s fate is something you will also share if you don’t act proactively.
4)Yes, finasteride and minoxidil can work for you. HOWEVER, I do NOT think that finasteride is enough for you. I do NOT also think that minoxidil in its topical form will be enough alone. You would need in my belief dutasteride (given your early hair loss) and either low-dose oral minoxidil or topical minoxidil with tretinoin for boosting its efficiency. Wherever the hairline is intact but diffuse-pattern hair loss is observed, eg. crown or diffuse thinning over top of the scalp, the medications work the best. Wherever there are bald patches, the medications work worst. Keep that in mind and start saving for a hair transplant (HT for short) in case the medicines cannot bring your hair in regions adjacent to frontal/temporal lobes, or regions known simply as “temples”. Because your temples have no terminal or thinned hair, all hair left there is vellus only, it will be hard to bring them back, your only hope would be for follicles to be still A)non-dormant (this is unknown, so don’t depend on it.) B)non-fibrotic (this is likely true, your follicles are unlikely to be fibrotic) but I would not put my trust on that even if your hair loss began happening equal to or in less than 2 years. Keep also in mind that I do NOT give any medical advice, dutasteride is usually speaking better for more aggressive hair loss, given your early balding it may be although not for sure a better option for you, ultimately always consult a doctor for any medical advice. You also must keep in mind that nothing in the world can bring your hair if your follicles go dormant, maybe pp405 but that is not on the market yet. If perifollicular fibrosis sets in, then not even the pp405 could bring it, your only hope would be some treatment that can regrow follicles out of thin hair, which is akin to hoping for a miracle.
You also probably would need fin/dut after a hair transplant, given your aggressive hair loss, but consult a doctor for that.
