I've just remover some shocking gel nails from someone who went to another mobile therapist & she has also had her lashes done. I'm not a lash tech but these looked like cluster lashes with a small bulb at the base of the lashes & she was told they will be in for at least 4 weeks. They are also really wonky on the inside corner. Are cluster lashes just for a few days wear or will they damage her lashes if they are on for 4 weeks?
