My lashes have always been thin and short. And I have overplucked my eyebrows so much they wont grow back. I started Latisse one week ago and have noticed my lashes look a bit longer and I've got new ones growing in. I cannot wait for 3 or 4 months to see the full results. I use a brush Its a concealer brush made by elf. I got it for $1 at target. I usually use 1 drop per eye/brow.
