This guide draws on four published sources on lifespan plus five more on the styles themselves. The taxonomy, the wrapping methods, the wash instruction and the 4–6 / 6–8 week windows. These come from Bangstyle, a hair publication, read September 2026. It is the only source that states the relationship between the three names cleanly, so it carries section 01.
The 4–8 week window and the afro kinky bulk listing. From Exyhair, a hair brand, read September 2026. Their own product listings are what revealed the human-hair version of this style: a "tight afro kinky bulk" sold for loc extensions, which is not a texture we carry.
The 4–10 week window. From Best African Salons (Wynn), a salon's own care plan, read September 2026. This is the widest published window.
The takedown method, the oiling, and the 7–11 week deadline. From Regirl, read September 2026. This is also the source that flags the crochet-method ordering problem: locs out first, moisture second.
The cost figure and the materials list. From Un-ruly, read September 2026, which lists the actual products used in a butterfly loc install: a named synthetic crochet braid and a water wave hair.
Trend validation. Butterfly locs are covered by Makeup.com, InStyle and PopSugar, all of which appear in the same search results. This is not a niche topic, and one hair brand (LionLocs) holds a top-five position on the lifespan query.
Our own products. Tressifine sells human hair in 100g packs: bulk from $54.99 and pre-separated crochet from $99.99, in 12–30 inch lengths. Our textures are deep wave, body wave and Burmese curly. None of those is a kinky texture, and these styles want one.
What we did not do. Faux locs were not installed, taken down or worn here, and no texture was tested against Marley or water wave hair. No night routine, maintenance schedule or reuse guide is published in any source, and we left those gaps open rather than filling them.
