1. Is it difficult to deal with long (APL and longer) natural hair?
Yes, my first go round was waist length and managing different textures (especially where they meet) was very challenging. I cut a style to shoulder/collar stretched but I am approaching lengths that are more challenging again. A few things that would make it easier but I am hard headed. 1. Wash and detangle in 6- 8 sections. 2. Keep it stretched most of the time (I have not straightened in 2 years and I do not enjoy wearing 2 strand twist. This is my biggest challenge). 3. Find products that keep your hair as tangle free as possible. i.e. mild cleansers, water-soluble cones and quats (if any at all), limit drying ingredients. Some products are temporary fixes (silicone laden and certain gels) but over time, they cause issues that require harsh surfactants.
2. Do you go through a ton of products?
Yes, primarily when I am lazy. When I section and distribute products, I use less.
3. If you are military or know a long haired napp in the military, how do you (or they) stay within regulation? I'm Air Force and for women the bulk of the hairstyle cannot exceed 3 inches(an example, I wore buns when my hair was long so my bun is not allowed to stick out further than 3 inches from my head). My ultimate goal is WL and my hair is thick so im not sure if it would even be possible for me to keep WL hair.
I am not in the military but doing a bun on dry, stretched wsl, hair would certainly yield > 3+ inches. If you do a wet braid and bun, you may fair better. However, there are perils with this approach as well. Your hair wants to shrink as it dries and this tension can cause damage as it attempts to contract. I always adjusted my bun accordingly when it was drying to relieve some of the tension. However, it did get bigger with each adjustment.
