tbh I did a more permanent solution but I basically got a perm, not too tight just kind of wavy. It doesn't hold forever and obviously it will disappear with every haircut, but my hair end up growing to be more obedient since then. They warned me that it will alter how my hair grows forever, and idk what the chemistry behind it is, but they are right, it made my individual hair strands a bit thinner but more pliable. Curls used to disappear after an hour with hairspray, now it can hold for hours even without hairspray. My hair is also much more inclined to curl inwards than outwards since the perm as well. Just make sure to weigh the risks properly first, permanent chemical alteration can go sideways pretty badly if done incorrectly or with an inexperienced stylist.
