hi! Would be really greatful on some Advice if been doing Russian lashes since December most days! But recently I've had a lot of clients come back in with in a few days with lashes missing some are saying there falling out a fan some are coming out as a singles lashes. A few Clients that are booked in for Infills by the time there Infills are due 2 weeks they have not a lot left mostly only on one side??? I'm really lost I making up my fans fine I'm hoping my isolation is correct as I'm always checking lashes are brushing theme through to make sure there all secure why are they not lasting?
