Can you use vaseline on dreads?

Yes you can use vaseline on dreads. I would not recommend starting dreads off with vaseline, but if you want to use it to grease your scalp I will use just a little.

If you use too much grease like vaseline, depending on the length and thickness of your dreads, when it's time for a shampoo you will have to use steaming hot water or as hot as you can stand it with shampoo to remove all the grease.

If you are starting dreads off I recommend using beeswax, or beeswax gel,or find a brand that you are comfortable with.
