Anime long hair isn't actually easy to draw at all

First is reference. Find reference of hair you like and copy that. You want to determine the light source. You have highlights in all directions so it's hard to tell where the light source is. Once you know the light source, you want to separate what is in light and what is in shadow. Then it'll be easy to render out whatever part you want. It's just managing values and keeping the form in mind. Spend some time on the drawing and really planning out the strands and how they are shaped. Some parts were confusing so I just made some stuff up, but when in doubt, just keep things bulky and simple. I think you did a good job of trying to separate the values, but the placement of everything is a little confusing.
