new to curly hair products (14, male)

Hi, I've been straightening my hair ever since about August last year, and it's getting a little frustrating for me. Instead, I want to make my natural wavy/curly hair my main style of hair instead. The problem is, I don't know what products to buy! If someone could give me a reccommendation of these products, it would really help:

1) Which conditioner?
2) Which leave on creams?
3) More curly hair tips

Thanks, this will help a LOT, trust me!
