Grey Hair at 23

I’m 23... and I have probably 30 full-strand grey hairs. 😭 I have never dyed my hair in my life. It’s naturally light brown, and very very thin/fine. And very straight (but frizzy in its own way). I don’t have the money to commit to dying my hair. And I have no clue what color even I could/should dye it, if I did. But I don’t want to look like an old woman by 25... is there anything else I can do? I know I cannot reverse graying hair. I’ve considered using a colored dry shampoo. I just don’t even know anymore. I’ve also read online that grey hair looks bad with warmer skin tones and my skin tone is olive. What do I do??? 😭😭
