Wash your lashes with diluted natural baby shampoo. Some people like to add tea tree for the antibacterial benefits. Just make sure you’re not using oil based cleansers. Here is a quick video to help you with aftercare. Ask me if you would like to get lash serum and I can pick some up for you. Products are also available online, but make sure they are lash extension safe. I am using GrandlashMD.
