It sounds like we might have similar hair types!
I don't have any tutorials, but some tips:
- Put it up when it is wet or damp. Otherwise (on me) it just all slides apart. This does limit the volume you can get in a style. If you need more volume, you'll need slightly dirty 2nd or 3rd day hair and/or a bunch of product.
- More bobby pins. No, more than that. Depending on how much hair and what style you're doing, you might need one or two of the giant ones. I like them for the 'base' of holding a lot of hair up in a bun, and then use smaller pins to secure the various edges or ends.
- Practice. You are 100% not going to get it on your first try, and the time after you're happy with it is going to be a hot mess. Practice will get you more consistent so you can do it without stress on your big day.
I generally go for simpler hair styles. Depending on your length, a simple 'ballerina' style bun is nice and easy to do. I let my hair dry about half way, pull it up into a pony tail and start twisting, and then secure with lots of pins. I like it because it can be a different look depending on where I put the pony tail. And I can cheat if I need to and use elastics for the pony tail, though I've gotten good enough with bobby pins that I don't need to. My test is if I give my head a little shake. If I can't feel anything move, it means I'm good to go.
The website linked looks like it has some great hair tutorials!
