"Regulus has the more gorgeous curls ever!" AND YOU WANNA KNOW WHY
becsuse.
for the longest time he just left his hair slicked back or combed over. (yes im pushing my choir boy reg agenda WHAT ABT IT) like he didnt even know he had curls till he was too lazy to comb it over one lazy morning and all of a sudden his head was a frizzy curled mess. (picture a horrible perm) he didnt even know until a slytherin first year who was jumping through hoops for his favor offered to teach him a bird repelling spell. after asking why, he was horrified and the first year apologized.
He tried potions and spells and chants and stones yet nothing seemed to help calm his hair... and he couldn't very well ask Sirius for help since his hair was much less coiled than Regulus's. After about a month of tireless effect (anger filled quidditch practices when he cursed every great wizard for keeping the one muggle custom of hating anything that isn't straight) he finally caved and called in reinforcements.
You know where I'm going with this, right?
HE CALLED LILY, JAMES AND REMUS!
Listening carefully, while James nodded without actually listening (occasionally saying things like 'mhm mhm yes sir you make a fine point.' to impress or bother lily enough that she'll like him ...she'll never admit it but she giggled a little internally) operation make 'regulus handsome again!' was forced in motion.
James tried a natural salve that his dad made that 'enhanced your roots and made your strands shine!' It sort of worked, except they found out that Regulus is allergic to unicorn horn dust and sapflowers.
Lily tried massaging oils that she'd seen her mom use occasionally (and Mrs Evans had the prettiest curls ever!) but it weighed down the strands too much since she applied enough for three people so regulus kind of just looked like Snape. (After regulus saw his reflection, he looked like he'd braved a fight with a dementor)
Remus, who'd been the last one to try anything, and who did the least for his curls (yet they still looking impeccable! fking lupin genes 😒) decided to lend Regulus some of his self made soaps and conditioners that never really worked for him. Regulus did, reluctantly, and found that the frizz was almost gone, and that it smelled very reminiscent of citrus and eucalyptus. In fact, they looked so good that not only did lily ask for the recipe and James berated Remus for never hooking him up with his idiotic talent for accidentally making things that work wonderfully, he was able to convince his mother to left him open his own gringotts vault (of which he planned to use to finally rid his surroundings of those horrid walls of horrid memories.) the end!!!!!! Idk when I wanted this to go but it went somewhere I think
