This DIY will show you how to make your own eyelash growth gel for under $10.
You will only need 4 things.
Castor Oil and Vitamin E will promote your lashes to grow strong and healthy.
Aloe Vera will heal your lashes and protect them as they grow.
Aquaphor will hold all the ingredients together as well as condition your lashes. I recommend Aquaphor of Vaseline because Aquaphor is water based and much safer to have around your eyes.
