We read fifteen published sources on these terms. The four-axes framing, the remy definition, and the rejection of single-donor as a synonym for remy. From Vera Hair Co., read September 2026, which states the distinction between alignment, chemical history and donor sourcing more clearly than anything else we found.
The virgin definition. From L'Oréal Paris and Indique Hair, read September 2026. The colour test for spotting treated hair, and the warning that mislabelling is common. From Haste Hair, read September 2026.
The conflicting single-donor definition, and the statement that the grading system was created by suppliers. From Indique Hair, read September 2026. The opposing reading of what remy means. From Vera Hair Co. We show both.
The cuticle-intact description and the root-to-tip orientation wording. From Luxy Hair and Perfect Locks, read September 2026.
Where non-remy hair is collected, and the 1A-to-10A scale. From Donna Bella Hair, read September 2026.
The weft constructions, the fine-hair recommendation and the row weights. From The Hair Shop, Perfect Locks and The Lauren Ashtyn Collection, read September 2026.
The term-frequency table. From our own corpus of 104 product listings, read September 2026. That is a count of titles on one platform, not a survey of the industry, and it describes what sellers write rather than what is true.
Our own products. Tressifine sells human hair in 100g packs, bulk and pre-separated crochet, without a weft. We do not label any of it virgin, remy, single-donor, drawn or graded, and we have not verified those claims for our own stock, so we state none of them. We sell hair, which is a commercial interest on a page about how hair gets described.
What we did not do. We did not test or inspect anyone's hair for cuticle alignment, chemical treatment or donor count, and we have no laboratory method for any of it. The single-donor dispute is left unresolved: two sources cannot be reconciled and there is no third. A piece arguing the virgin label is often a lie appeared in the results but its page had been removed by the time we tried to read it, so it is not used here.
