I have curly hair, but it is extremely fine! I hated it at school, but as I always had long hair, once a teenager (and older) could put it in a "updo" in a number of ways!
Sadly, as I got older, it became thinner and did not look good still being long - so at age 50, I had it cut short and keep it that way. My hair has always dried quickly, so I never needed a hair dryer. I still have a Babyliss hair curler, which I use (to provide volume) if I'm going out somewhere where I want/need to look good - but that's very rare now (even before Covid)!
My hair is mostly fine, except in mizzle or rain - when it still goes very "frizzy curly". It's more wavy now, rather than curly. John Frieda are the only products that worked for me some years ago, when I was still at work, and needed to look "smart/professional".
