We need a "My hair won't naturally dread" support group!
This seems like the appropriate place to mention that it's possible to go even further into extreme neglect, but it's something most people are not comfortable doing. It could be called the 'ascetic' method. It will get reliable results quickly. You are able to wash your hair one last time thoroughly with only shampoo, get out any residues, and then, stop using shampoo of any kind, completely. You rinse your hair with plain water only, as often as you want.After a few days, you will see the oil building up on your hair. Keep waiting. Don't wash it. You will have to resist the temptation to wash your hair with some kind of shampoo, and you'll sit there wondering if you can use some other substance that will be similar to shampoo or soap. Use only water and resist the temptation. Your hair will definitely look greasy by now. It will start driving you crazy and you will feel disgusting.After a few weeks, your hair will stick together in greasy strings. This is too gross for most people to tolerate, and that is why most people don't do their dreads using no shampoo and extreme neglect. This is the way that I made mine. If you can put up with this, you will have sticky strings in a couple weeks. A short time later, the roots closest to the head will start to form mature, matted, 'real' dreadlocks, while the hair farther away from the scalp will still be just a string of hair that is hardly tangled at all. You don't need to worry about whether your hair is tangling or not. The greasy strings keep the hair sticking together enough to make the roots get matted.That is the 'desert island' method of getting locks. That is why humans had locks before shampoo and soap were invented, and that is how the donkeys and dogs and other animals who have locks are doing it without backcombing or washing or anything.
