When we think about lash shampoos we are used to checking their ingredients for any oily compounds. The difference between regular lash adhesives and Dark Matter is that DM is not afraid of oils but it is sensitive to high alcohol content products. So do check your lash prep foam and the shampoo you recommend to your clients for home use to guarantee maximum retention. Also, do not forget about any additional products that clients might use on their faces such as make-up setting spray (most of the setting sprays have a high alcohol content)
