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)
How to find out if your lash prep shampoo or your clients' shampoo has a high alcohol content?
The following alcohols are particularly used in cosmetics: ethyl alcohol (ethanol) and isopropyl alcohol (isopropanol) and the polyhydric alcohols glycerol (commercial name glycerine), propylene glycol, butylene glycol, pentylene glycol and hexylene glycol.
The systematic names are derived from those of the parent hydrocarbons by appending the suffix -ol. So look for any ingredients with the “-ol” ending!
Product ingredients are always listed in a descending order meaning the ingredients listed first make up a bigger % than the ingredients listed later. Since it is only HIGH alcohol content products that react to DM look for the “-ol” endings in the beginning of the ingredients list. If you see and “-ol” ending as the last ingredients you don't have to worry about the shampoo affecting your Dark Matter retention.
When you notice some of your clients experiencing worse retention than others we do recommend checking their lash shampoo for any alcohols asap. If you are unsure about which ingredients are alcohols or if the alcohol content is high enough to affect retention you are welcome to email our customer service at email@example.com with a picture of the shampoo's inci and we can check it for you. There are several great lash cleansers on the market that have been created to be used with regular lash adhesives but are not compatible with DM.
