I had my lashes done already two times without allergic reaction and I did a patch test before too without any problems
The third time I did then, the lashes were badly applied causing me a bad allergic reaction that left me with bad swollen eyes and headache
The eyelashes removal was too bad too I've lost a lot of my lashes hoping that they're gonna grow back.
One only advice: don't go there if you want to get your lashes extension done!
