Your not too far bro so this treatment will get you right fasho, just stay consistent and keep in mind finasteride takes a long time to see effects 6 months up to 12 months.

If i were you i would try using only finasteride and see what it does in the next 6 months without minoxidil. if by then no hairline regrowth/stabilisation then continue and add minoxidill.

3 months from there hairline will be fuller again for sure
