Finally found this video which clearly shows how to pin the hair when using hair donut. Many other videos either hands were blocking their pinning or going to fast…
I did something like this for my self I got long hair and I kinda braided each side twist and then put another thinner band over it and I like it’s a wider bun so cute I just leave out my little side and baby hairs and it’s much better someone does for u . I’m a only girl and never had anyone but a friend who had 4c hair she was African and knew how to. Braid n stuff
To be honest I usually don't use a donut for thick hair because you can get a great donut shape without it. For thick hair I usually just do a regular classical bun and it ends up looking like a donut bun! I have a tutorial for that too if it helps - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gpHxAJRlgYw.html&spfreload=5
