Q. I cut my dreads open and found greasy crap in it!
A. If you are talking about a greasy mess, then you probably created your dreadlocks the wrong way. Either you used too much wax or gel or you have not allowed your locs to dry after washing them. The hair products are not the problem here, it is the use of them, and the care afterwards.
Despite what you may read elsewhere, all dreadlocks have some amount of hair product, skin flakes, and skin oil in them. This is simply a fact of having matted hair on your head.
There is no such thing as a “residue free soap”. However there are certainly soaps that leave less residue – this is why it is important to use all natural ingredients in your hair products. Wash as often as you can, and DRY YOUR DREADLOCKS. Use a hair dryer!
If your dreads are too greasy to fix, then pick them out and start over. Use a quality, all natural gel or wax to create your dreads, then wash often and DRY YOUR DREADLOCKS.
If your hair is just a little greasy, soak them in hot water to help loosen anything out of them, then wash them deeply with a NATURAL soap. Then dry them out as best you can – use a hair dryer, this is very imrportant. Other than that - don’t worry about it too much – that is just the way it is when you have dreadlocks.
