Why fiber whips shed, from a guy who builds them (and what actually helps)
I build fiber whips for a living (Ants on a Melon), so grain of salt. None of this is brand specific though, it's just how fiber optics behave, and it applies to every whip out there including ours.
Why they shed
The fiber is a thin plastic light pipe. Every bend, snap and drag flexes it, and the ends are where it gives out first. So some shedding is normal on any whip that actually gets used.
Sparkle sheds fastest, and that's not a defect, it's how sparkle gets made. The shimmer comes from tiny nicks cut into the fiber so light escapes out the sides, and every one of those nicks is a weak point. If you flow hard or body trace a lot, end glow will last you a lot longer. Sparkle is gorgeous for lighter use and for video.
What actually helps
A little silicone lube worked through the fibers keeps them gliding instead of grabbing. Small amounts, a small bundle at a time. We recommend Swiss Navy silicone personal lubricant. Yes, really. It's pure silicone with nothing else in it, which is what you want on fiber, and it's easy to find. Here's us doing it: https://youtu.be/Kz8ieRQJltg
New thing on our end: we started pre-lubricating every whip around the start of August, so anything shipping from us now arrives already done. If yours came before that it didn't, so give it a once over. Either way you'll want to redo it when it starts feeling grabby again.
Smooth or mesh fabric beats bare skin for tracing. Fibers grab skin, and grabbing is what pulls strands loose. We made a whole video on what to wear: https://youtu.be/cBb7YLs04qw
Don't hold or swing the whip by the fibers. The bundle root takes all of that load.
Heat warps fiber. A closed car in summer gets well over 130F, which is plenty to do it, so don't leave a whip in one. Storage and travel video if you want it: https://youtu.be/ESmRulKy8RY
Trimming is fine! If the ends get scraggly, cutting them back to a fresh length with scissors doesn't hurt a thing.
And if you want to give one a proper deep clean, that's its own video: https://youtu.be/cg-N6l8LIX8
Happy to answer anything about fiber construction, counts, lengths, or whatever weird thing your whip is doing :)
