The interaction between laser light and living tissue is defined as photobiology. Photobiology can be subdivided into laser-tissue reactions defined as photochemistry and photophysics—that is, stimulation of chemical or physical reactions by laser light.
Why is my hair thinning? What causes baldness? These are common questions asked by individuals suffering from hair loss.
The most common reason for hair loss in women and men is Alopecia Areata, also known as pattern baldness. Although it is inherited genetically, it is not always predictable. It can cause thinning hair or bald patches, and can sometimes be slowed with medications like Rogaine (Minoxidil) and Finasteride. Other causes include scarring, stress or pulling on hair, and damage to hair follicles.
Hair growth can be affected by external factors such as medications, illness, infection, or exposure to chemicals. Pregnancy can also occasionally lead to temporary hair loss in women. However, it is often difficult to know exactly what causes hair loss in men or women, so it is recommended to schedule a consultation with a physician.
