First you need to find out where the smell came from. If it's just a moldy smell it's probably because you don't dry your hair well after washing them. Or if you sleep when your dreads are wet. But you probably just need to wash your hair.

Washing your hair on a normal basis will keep your dreads from growing bacteria. But if you do have bacteria growing in your dreads soak them in rubbing alcohol and wash it out. This will kill all the bacteria.

Icky! Wash the dread locks really good, and soak the moldy part in rubbing alcohol. The reason mold begins to grow is because the dreads aren't getting dry, make sure you squeeze the water out of your dreads when you wash them, and towel dry them or use a hair dryer.

Which wax should I use?

There are many different products out on the market that say they are intended for dreadlocking hair, but that does not mean that they actually work. Any wax that has the ingredient of petroleum is bad for your dreads, it will make your dreads feel nasty and it will make your dreads fall apart. There are 3 waxes that are appropriate for dreadlocking hair:
1. DreadHeadHQ
2. Knotty Boy

1. DreadHeadHQ-this is my favorite wax. It has the strongest hold.

2. Knotty Boy-this wax is pretty good over all. Decent hold. Its main problem is that it's greasier than it needs to be and the hold, while long lasting, isn't that strong. I also think the smell of their wax is a bit much. At first I was like mmm yummy, but after a week or so I was like sick to my tummy.
