Here I will address some of the (perceived?) issues that I have had with my Sisterlocks over the past 2 1/2 years. These are topics that have been discussed on the LockItUp webgroup, but which do resurface as new members join and relay their experiences with their SL journeys.

In the early days, before my locs actually

"settled", (I thought) there was a problem with an abundance of loose hair around my hairline. Eventually though, this hair began to entwine itself in the nearest lock, thus alleviating that problem!
Not so long ago, I also was curious about a few locks that had "holes" in them. I eventually came to understand that this was probably a result of not retightening correctly. It could have come from not using enough tension while holding the lock when retightening, or perhaps from

inserting the tool in the same direction during a rotation. There could be other reasons why this happened that I am not aware of (who knows?)

Here we have a shot of one of my "two headed dragons". This type of loc comes from combining 2 locs together, usually to provide more stability at the root of the loc(s).
Now today, almost 3 years into my journey, the only issue I am dealing with is tryingto keep my parts

straight. Actually, it's not so much the straightness of the parts,

but it is the catching and snagging of the hairs from other locs that is the problem. You know how much discomfort those little hairs can cause, when they get caught in a neighboring loc. I have very creepy, crawly, clingy hair, which just loves to grab onto other locs, especially in the kitchen area, causing me to have to "pop" the stray hairs ... OUCH! I do the best I can when retightening, but this is something that I will leave up to my consultant to fix when next I see her.

If you find that you have any of the aforementioned "issues", the only advice I can give is to talk to your consultant first, before you try to make any corrections yourself (you might wind up making matters worse). And many times you will find that leaving your locs alone to do their own thing will resolve the problem.
Peace.
