Hello there, I do not have dreads. Yet.
If you need to brush that much, yeah it should happen really fast. Just get rid of your comb and brush. Get yourself a good residue free shampoo, and be happy. Separate as needed (usually 1-2 times a week, but for you maybe after each wash). wash your hair 2-3 times a week. Ignore your hair itself. Just focus on cleaning your scalp. as you rinse, the soap will run through your hair cleaning it.
Don't worry about "what hat your should wear", "what kind of pillow case you need", or any of that other stuff. Locks happen no matter what you do, and if your hair really tangles that fast, you really don't need to do anything to "speed" it up.
I'm glad you decided to lock up. It's so much fun, but you're right, there is a ton of misinformation out there. Some of it is ok, but there are so many people here willing to give out free advice. Why would you waste your time looking at a website made by one person
