Saralash, I had a client today came in and told me that her lashes shrink since she stopped using lash growth serum/conditioner. I am curious if it is okay for clients to use revitalsh or other lash growth conditioner while having extensions?

I want to retail EE makeup friendly. Today, another of my clients came in with only less than 10 lashes per eye (2 weeks return). She uses eyeliner everyday and heavy makeup, plus, she is more on the oily side. It made me think that I should start retail EE eyeliner and mascara friendly but not sure what brand to retail.
