Used correctly, these chemicals are typically harmless. However, in some people, they can provoke various reactions ranging from redness and swelling of the nail bed to damage to the nail root, causing deformed nails. Serious injury and even death can occur if the chemicals are swallowed.

Experts urge people to use these products according to the manufacturer's instructions. This should sharply reduce the risk of an adverse reaction. If you think you might be susceptible to an adverse reaction from a product, apply it to a small area of your skin or nail and wait for 24 hours. If you have a reaction, avoid using the cosmetic in the future.

Salon Surprise

Leaving your nail care to the professionals does not necessarily guarantee a worry-free experience. Nail salons can also be a source of health dangers.

Although states generally impose strict sanitary regulations on salons, some facilities ignore the rules and slip through the cracks. It can be difficult to know whether or not a salon is cutting corners. One way to tell is to look for posted certificates that indicate that both the salon and the individual technicians have passed licensing requirements. If these certificates are not visible, you shouldn't go ahead with the treatment.

In addition, look for telltale signs that a salon may not be adhering to all the rules and regulations. These include bargain-basement pricing, dirty floors or counters and general disorganization.
