Rebirth, yagi (athu) from Japanese have quite some long hair comics in e hentai or other similar websites.

Milftoon specifically inusan has a few comics that you already showed. There is an artist called D (dvd-r) he has a few comics also.

Long hair adult comics is quite rare, there seems to me more irl content but not artistic content.

There are few artists that focus on long hair like wildhl, hairjob heaven, redrollerball, and few more but these are artists.
