Rhetorical Natural Hair Questions

Have you ever wondered the answers to these questions? Either I find they are so controversial that there is no one answer or it's impossible to find a solution. If you have any answers, please reply w/the solution and your hair type.

1. How can I achieve the perfect wash n' go?
2. Is shrinkage a good thing?
3. Is natural hair for everybody?
4. What's the best shampoo for my hair?
5. How can I make a dry patch grow back? (no seriously, it's been about 2 years without growth)
6. Is the hair typing system that big a deal? They're just numbers, right?
7. How can I part my hair perfectly?
8. Should I go see a dermatologist?
9. Should I take vitamins specifically for my hair's health purposes?
10. What are the quickest and flyest protective styles?
11. Which is better - a satin pillowcase, scarf or bonnet?
