Some locticians remove these buds that sometimes form at the end of locks. The buds are actually welcomed by others because they mean the hair is not going to unravel out of the locking framework. Sometimes lock clients will remove these buds without the loctician's permission because they (the client) don't like them.
Pictured are some of the buds that I saved from my lock tightening with my third Sisterlocks certified consultant. She went through ripping as many of the buds off of my locks as she could. I did not request this type of lock grooming, but she insisted that the buds are not supposed to be there. I lost some length because of her ripping them off with her hands. In hindsight, I realized that she should have just went through with shears and snipped what she wanted removed.
Now, jumping forward to present day, most of my locks have coiled back up and formed buds again. Why? I believe that it is my hair's natural behavior to "roll up and park." So removing the buds at the end of locks where the client's hair naturally coils into itself is a waste of time and money.
There are exceptions. If the buds are too large to feed through the root of the lock without ripping the whole lock out of the head during an interlock tightening then the bud needs to be trimmed or reshaped to maintain the integrity of the lock.
Lock grooming is usually a separate session from the tightening session.
Also, I think the budding at the end of the locks are more synonymous with the interlocking method versus the twisting of locks. The interlocking method actually uncoils the hair allowing the shedded strands to drop down the locking framework of the lock and rest at the ends.
As for me, I am okay with my buds at my ends. Some may fall off on their own. If not, it is all good with me!
