Even if you have never had an allergic reaction to metal, the constant use of alloyed metal and metal-plated earrings can cause a metal allergy reaction. This is because sweat and moisture can corrode the plating and/or cause metal to oxidize, resulting in a chemical change and skin irritation. Unfortunately some metal allergies do not go away and will worsen if you continue wearing the offending material.
Titanium is a hypoallergenic material used in the medical field and is gentler on skin than gold or platinum. It contains no nickel, which is said to cause metal allergies. Although Titanium is not a widely used material in the jewelry industry, it has many properties that make it well suited for jewelry making. For these reasons I use, or can provide on request, Titanium earring posts and hooks on most of my earrings.
The benefits of Titanium: Titanium is hypoallergenic. In fact, Titanium is the most hypoallergenic of metals, and is rapidly replacing other surgical implants (prosthetic implants such as hip, shoulder, and jaw) and surgical instruments (scalpels, hemostats and tweezers), since the body does not react to it. Also, Titanium earring posts and findings have become increasingly popular over the years because they are more resistant to corrosion when compared to other metals and they do not need to be coated to protect from rust. This means anyone can wear Titanium whether you have sensitive ears or not. Titanium earring posts and findings are stronger than those made from most other metals, because of the innate strength of the Titanium metal. This means that they are a better option if you do not want your earring posts to bend out of shape over time. Due to their durability, Titanium earring posts and findings are the best option for people looking for earrings that they can wear on a regular basis. Titanium earrings will not be affected by normal wear and tear as fast as regular earrings and are easy to take care of and maintain. The natural gray luster, and the anodized colors of Titanium earring posts and findings lasts throughout their lifetime. You only need to wipe the metal down occasionally with a soft cloth dipped in warm soapy water to maintain their shine.
