1601: From the Middle English hybrid (offspring of plants or animals of different variety or species), from the Latin hybrida, a variant of ibrida (mongrel), originally describing the offspring of a tame sow and wild boar, the origin of which is unknown but etymologists suggest it likely evolved under influence of the Ancient Greek ὕβρις (húbris) (outrage) and it was cognate with the Latin iber & imbrum (mule).  Hybrid was first noted in English in 1601 but use was scant outside of technical use until stimulated in the 1850s by the boom in the sciences of botany and plant breeding, the adjective attested from 1716.  The first hybrid car was the Lohner-Porsche Mixte Hybrid, released in 1901 and based on Ferdinand Porsche’s (1875-1951) earlier electric vehicle, the Electromobile although the first car actually badged as "hybrid" to indicate an "automobile powered by (1) an engine running on electricity and (2) an engine running on fossil fuel was released only in 2002.  The noun hybridity (state or condition of being hybrid) dates from 1823 while the intransitive verb hybridize (cross or inter-breed) was from 1802, the transitive sense of "cause to interbreed" emerging in 1823.  Hybrid is a noun & adjective, hybridize is a verb and hybridity, hybridism & (the awful) hybridisation are nouns; the noun plural is hybrids.

Categories of Eyelash Extensions

Classic Eyelash Extensions give a semi-permanent mascara look.  The technique is to attach what’s as close as possible to the thickness of the natural lash to each strand able to support the load.  They can be applied in different lengths, thereby emulating either the look of mascara only or something both longer and lusher.  Lifespan is two-four weeks depending on body chemistry, lifestyle and care routines.

Clusters or Party lashes are intended to be single-use, worn for no more than a day although, under good conditions, they can last several.  It’s not recommended to wear them for more than two-three days because, being much heavier than other extensions, they can cause damage.

Italian volume.  The lovely "eyelashes" on the Lamborghini P400 Miura (1966-1968) were carried over to the P400S (1968-1971) but were unfortunately not used on the P400SV (1971-1973).  Because of the fundamental design, the Miura had flaws which could to some extent be ameliorated but never wholly fixed.  Few now care because it's so achingly beautiful.    

Express lashes are the A&E of the profession.  Done in minutes, the strands are simply glued to the natural lashes and, because eyelashes grow at different rates, damage can happen if they’re worn too long.  They don’t provide a look as good as other techniques but, apart from their intended purposes of cheapness and speed, there exists in subsets of several groups, the niche market of the obviously fake.

A mix of Classic Lash Extensions and either Pre-Made or Russian Volumes, Hybrid volumes make possible some dramatically textured looks but, unless the mix is purely symmetrical, it needs a trained operator to weave a pleasing design.  The most popular contemporary interpretation usually blends strategically-placed long lengths of classic lashes, filled-in between with volume extensions.  Some operators call this look The Spiky.

Real Russian Volume lashes are much lighter than classics and are manipulated by hand, with special tweezers, to create a fan or bouquet of lashes which is then placed onto a single natural lash.  Slow and expensive, each fan is wrapped around the natural lash, not just placed on top and that creates greater structural integrity so they tend to be longer-lasting.  Some lower-cost operators sell what they describe as Russian Volume using pre-made fans which are just placed on top.

Pre Made Volumes are fans or bouquets of lightweight lash extensions, glued or heat-bonded at the base.  They emulate the look of Russian Volume but don’t last as long; at a distance the two are indistinguishable but up-close, the pre-made fans can’t match the flow and flutter of the voluminous Russian.
