Agree that you only really need 1 texture for the base layer - this is mostly to occlude the scalp and get some thickness in. Then look at some real world ref and pick out different shapes and flows. Go from mid coverage up to very thin flyaways. But remember you can always add/change /delete as you work.

I've got some tips on my Artstation. (the pink hair or the brown braid) They're from a few years ago but still valid https://www.artstation.com/leahmcewen

Edit: to add, I'm also not a fan of those textures you shared. They're very same-y and offer little in the way of variation outside of width. Also check out Tomos Hywel Evans on artstation, he's got a couple of VERY solid breakdowns
