The problem of hair, which takes up a large part of human appearance, causes many people to suffer from hair loss, the most serious of which is hair loss. The ancients were extremely generous about hair loss because of heredity, but in the modern times, much attention has been paid to appearance, and many have become interested in hair loss. Modern people are suffering from a lot of stress, hair loss is rapidly progressing not only to the elderly and young people, but also a lot of hair loss has appeared as a worry. In general, alopecia refers to a condition in which hairs are normally missing. Hair loss was previously thought to be simply a genetic factor. However, various studies have not confirmed the exact cause in recent years. It is known that the action, stress and the like does not cause hair loss itself, but it causes hair loss by lowering the function of the papilla and hair follicles and damaging blood vessels.

In addition, there are various causes such as lack of nutrients to hair roots, stress caused by dyeing, drying and perm. As the various causes are revealed, the symptoms appearing according to each cause are different, and various treatments are developed and used accordingly.
