19 with a hairline like this and thinning on top, any suggestions?

[k9gatton]

When I was about to turn 19 i noticed to slightest bit of thinning on top, and now have lost a lot more, any ideas on what to do with my hair from this onwards?

That's already between a Norwood two and three. Classic male pattern Norwood androgen alopecia.

Get on Finasteride (one milligram, wouldn't go higher than that), and Minoxidil foam (five percent)
twice. Do it ASAP.

Time is important.

Dying hair can be revived, but the window for the hairline is small.

Also, Minoxidil DOES work on the hairline. But only use it after taking Finasteride. Without an
anti androgen agent, Minoxidil effects will only be temporary.

You can expect shedding for three to four months (between 12 - 16 weeks).
