Beginner to hair

I’m a sixteen year old girl and I only really know how to straighten my hair. I grew up with a young mother and all her friends which all done some sort of beauty work in college or as a job so I never really learnt how to do it myself because they were all there to do it for me. Anyways, I focused more on makeup when I was about 12 and can do that flawlessy but now I’m still stuck on hair ☹️ I feel like my makeup feels incomplete when my hair is just straight and flat. I have ginger hair and I feel like my gorgeous colour is going to waste without knowing how to do anything with it. I have been watching YouTube tutorials and bought some curlers and rollers recently but I’m on here to ask; what advice would you give to a beginner when learning how to do their own hair?

I think I should add I’m talking more as in blowouts and curls; I want big hair. I’ve been watching a lot of 2000s girly films recently and they all have big gorgeous hair, any help would be appreciated💘
