My dreads make medallion shaped knots on the ends. These knots start curving into them selves and then round out.and form round balls on the ends. The 1st picture gives an example of a few of the baby dreads on my head. They have already gone through the medallion stage and have turned into balls. The tips will always be a bit thicker because there is so much more hair balled up than there will ever be on the rest of the dread. The second picture is showing a 7 year old dread. See how it is so much fatter on the end? It is my most extreme one. So yes....those balls will always be thicker, but they will not be as noticeable It does not bother me at all that they are fatter on the tips.It is just the way mother nature wants my hair to knot. What bothers me is when people tell me that I should leave my tips undreaded. LOL I do not have a choice in the matter. I have even combed out a tip or two but guess what? It just does it again! Embrace it and love it ! It is your dreads and your journey. Don't worry about what other peoples dreads look like and never compare them to yours! Yours are unique and beautiful! And have lots of personality!!!
