Russian volume lashes or just volume lashes started from Russia and were invented by Russian Olga Dobronravova. Russian volume technique allows to use more lashes on one natural eyelash, because the lashes are much finer and lighter than normal classic lashes. Classic lashes have to be applied in one by one technique, but with volume 2-6 lashes can be used with 0.07mm thickness. Most common classic lashes come with thickness 0.15mm and 0.20mm, but volume lash thickness is only 0.05mm, 0.06,mm or 0.07mm. 3x0.07mm weight the same as 1 classic 0.15mm lash and 5-6 0.07mm lashes on one eyelash should be maximum amount and only people with naturally thick lashes can have 5-6 lashes on one eyelash.
Volume lashes are like creating an art, 2-6D fans have to be hand made, open, fluffy and soft, it's also important to use less glue and right products. Faux mink and silk is used to create volume lashes, mink lashes are more matte, silk is more glossy, they have the same quality and softness. I only use synthetic mink lashes, as they are soft and hold their shape.
It is totally normal than volume lashes take 2-3 hours to apply and even very experience technician take 3 hours for full sets.
As volume lashes are very much in trend now here in Australia, it's also sad to see that many eyelash technicians haven't done proper training and they actually apply volume lashes as classic lashes.
This is not proper volume! Fans are all closed and are way to thick and clumped. If you see people advertising 10-12D lashes, then this is actually way to heavy for natural lashes. The thinner the lashes, the more lashes you can use on one eyelash, but even with 0.05mm 7-8 lashes in a fan would be maximum. Most of the Asian lashes can't handle more than 3-4 lashes on one eyelash. I've seen a lot of people advertising their volume lashes that are full, but actually just look like classic lashes, they haven't been doing fans and this is where people can charge cheap price and take less than 2 hours. It is totally normal to pay $200-$250 for full volume set.
Volume lashes have to look fluffy, soft and full and if you want to have volume lashes, please be ready to lay still 2-3 hours.
