What are the cons of eyelash extensions?

The cons of eyelash extensions include maintenance, cost, and potential risks to natural lashes. Extensions require refills every two to three weeks, which can be time-consuming and expensive. Improper application or removal can weaken or break natural lashes. Allergic reactions or irritation from adhesive are possible for some people. Daily care routines must be adjusted, including avoiding oil-based products, rubbing, or sleeping face down. Additionally, overuse or heavy application can put stress on natural lashes. While extensions enhance appearance, they require consistent upkeep, careful handling, and professional application to avoid negative effects.
