Suoristuspihi

Suoristuspihi, also known as a straightening clamp or straightening iron, is a hair styling tool used to smooth and straighten hair. It typically consists of two heated plates that are pressed together, with the hair passed between them. The heat and pressure applied by the plates cause the hair's keratin structure to temporarily change shape, resulting in a straighter appearance.

These devices usually operate by using electrical resistance to heat ceramic, metal, or coated plates. The temperature can often be adjusted to suit different hair types, with lower settings for fine or damaged hair and higher settings for thick or coarse hair. Many modern suoristuspihit incorporate features such as steam, ionic technology, or tourmaline coatings, which are claimed to reduce frizz, enhance shine, and minimize heat damage.

The basic operation involves sectioning the hair and then gliding the heated plates down each section from root to tip. It is important to use heat protectant sprays before using a suoristuspihi to shield the hair from potential damage. The effectiveness and longevity of the straightened style can vary depending on hair type, technique, and environmental factors like humidity. While primarily used for straightening, some individuals may also use them to create specific styles like waves or curls by altering their technique.
