The reason blepharitis and demodex will occur is because of the lack of hygiene/care on the client's part meaning they are not cleansing their lashes properly nor consistently.
That being said, Lashbath Rose Hibiscus was specifically created to thoroughly remove dirt, makeup and debris from the lash line and consequently will prevent ALL the condition mentioned above.
Additionally, one of the main active ingredients of Lashbath is: "Eriobotrya Japonica extract".
This extract  is subtropical fruit tree with high medicinal value native to China. Different organs of loquat have been used historically as folk medicines and this has been recorded in Chinese history for thousands of years. Research shows that loquat extracts contain many antioxidants, and different extracts exhibit bioactivity capable of counteracting inflammation, bacterial infection, aging, pain amongst other things.
