While overabundant moisture damages nails, so does a lack of moisture. That’s why drying household chemicals, the oil-zapping ingredients in some face products, rubbing alcohol, and some nail products are so damaging to nails – they dry nail keratin out. When moisture is taken from nails, the nail cells shrivel. The result? The smooth, tight interlocking of nail cells becomes disrupted; in its place is a bunch of ruffled, barely joined cells, which lead to nail weakness, brittleness, and breaking.
If there’s one thing that really dries out nails, it’s nailpolish remover. In fact, nail-polish remover is the reason most dermatologists recommend that you manicure nails no more than once every 7 to 10 days. Nail polish remover works by dissolving nail polish. There are two types of remover: acetone and non-acetone. Acetone removers have a reputation for being especially drying. Non-acetone removers, usually formulated with a chemical called acetate, are billed as gender to the nails. Yet, despite the claims of many nail technicians and cosmetic companies, both remover types are drying.
