I have always known castor oil can help with hair growth but this product delivers beyond that. I can already feel a difference even after using just for a few days. Currently, I am applying it on my eyebrows and soon will try out on eyelashes. I put a drop on each eyebrow before going to sleep and comb it evenly using a mascara brush. In the morning you can see that the oil has properly absorbed to the hair-roots and eyebrow already looks fresh. Try it!
You can get this eyelash serum from Amazon by searching for it here.
