Lash adhesive can be a delicate subject for those suffering from fragile lash lines or sensitive eyes, but bad lash glue isn’t good for anybody and can have painful consequences. An adhesive that dries out clumpy will inevitably irritate a client’s eyes and remove their natural hairs upon removal or the natural shed of the lash line throughout the coming weeks. Damage to an individual's natural lashes can make their hairs brittle, weak, and cause chronic irritation (due to the chemicals within the formula). Using poor products and adhesives will compromise your eye makeup, and ultimately your reputation as a professional lash technician.
