Infrared Curler vs. Ceramic Curler: The Science of the Heat
Choosing between these two technologies depends entirely on your hair type and your styling goals.
Infrared Curling Irons Infrared tools use a specific wavelength of light to heat the hair from the inside out. This is a very gentle process because it does not rely on high surface heat to shape the hair. Because the heat penetrates the core of the hair strand, the style tends to set more deeply and last longer. This is an excellent choice for someone with very thick, coarse, or "stubborn" hair that usually loses its curl by midday. It also helps to lock in natural oils, which results in a very shiny, frizz free finish.
Ceramic Curling Irons Ceramic is the most popular choice for a reason. These irons heat from the outside in and provide a very consistent, even temperature across the entire barrel. This prevents "hot spots" that can cause damage. Ceramic tools are ideal for fine to medium hair types because they provide the right amount of grip and tension to create a bouncy, voluminous curl. While the hold might not be as "locked in" as infrared, ceramic is the best for achieving that classic, soft salon blowout look.
1" Barrel vs. 1.25" Barrel: Which Size is Right for You?
The difference of a quarter inch might seem small, but it completely changes the structure of your hairstyle.
The 1" (25mm) Barrel This is the most versatile size and the industry standard for a "true" curl. Because the barrel is smaller, it creates a tighter coil with more structural support. If your hair is fine, very straight, or sits at a longer length, the 1 inch barrel is usually the best choice. It provides enough tension to keep the curl from dropping, and even as the curls relax throughout the day, they will still maintain a beautiful, wavy shape.
The 1.25" (32mm) Barrel This barrel size is designed specifically for the "Lived-In" wave or the "Beach Wave" aesthetic. It creates a much larger, looser loop. Because the arc of the curl is wider, gravity has more surface area to pull on, which means these curls will naturally fall faster than those from a 1 inch iron. This size is perfect for people with hair that holds a curl very easily, or for those who want a soft, romantic bend rather than a defined curl.
Pro Tip for Both
Regardless of the technology or size you choose, always remember that the hair sets as it cools. If you find your 1.25 inch waves are falling too quickly, try pinning them to your head for ten minutes while they cool. This will give any barrel size a much longer life.
