Girls, old and young, HELP PLEASE

I have always thought that my mother or my older sister would help lead me into womanhood. They would teach me all the things you need to know: about makeup, your cycle, how to style your hair, etc. Nobody did, and so I am CLUELESS. I know there a lot of older, and even younger, women on this app. I would really appreciate if any of you could help me. Here are some basic questions you can answer (if you want to), but I would be grateful for any advice:

- How do you curl your hair?

- How do you do a “full face” of makeup?

- Best way to contour a rounded face

- How do you do eyeliner with hooded eyelids?

- What should you do if your period stops randomly?

- What is the best way to keep the hair on your legs from growing back super fast?

- Is there anything that can help acne?

- What is the best way to lose fatty weight?
