Temporary bonds influenced by the hair's pH level.

The methods used to induce curls have shifted from primitive heat sources to sophisticated electronic and chemical treatments. 1. Thermal Styling (Temporary)

Always apply a heat protectant spray before using thermal tools to create a barrier between the hair and the heat source. Hair_Curling.7z

To understand how hair curls, one must look at the microscopic structure of the hair shaft. Hair is primarily composed of a protein called . These protein chains are held together by three types of chemical bonds:

These methods rely on the hair drying into a specific shape, which "resets" the hydrogen bonds without the potential damage of high heat. Temporary bonds influenced by the hair's pH level

Weak bonds that are easily broken by water or heat. This is why hair can be reshaped when wet or hot but returns to its original state when re-exposed to moisture.

Regardless of the method, frequent curling can lead to dryness and breakage. To maintain hair integrity: Thermal Styling (Temporary) Always apply a heat protectant

These allow for tight, defined ringlets on various hair types. 3. Chemical Processing (Permanent)
