What are the negatives of eyelash extensions?

The negatives of eyelash extensions include cost, maintenance, and potential risks to natural lashes. Extensions require regular refills, which can be time-consuming and expensive. Improper application or removal may weaken natural lashes, sometimes causing thinning or breakage. Some people may experience irritation or allergic reactions to the adhesive if sensitive to the ingredients. Daily habits also require adjustment, such as avoiding oil-based products and being cautious when washing the face. Sleeping positions and eye rubbing must be monitored to prevent damage. While extensions provide beauty benefits, the upkeep and possible side effects are important to consider before committing.
