Understanding : Vitiligo A Skin Conditions Beyond Color
Abstract: Patches of skin that have lost their pigmentation are the hallmark of vitiligo, a chronic skin disorder. The afflicted skin patches turn white and typically have strong edges. Additionally, the skin's hair may turn white. There may also be issues with the inside of the mouth and nose. The rate at which skin conditions cause color loss is uncertain. When the cells that make melanin cease to function or die, …

Alopecia Areata: Complex Roots and Potential Cures
Abstract: Autoimmunity is when the healthy organs of an individual’s body are attacked by its own immune system, leading to illness or functional abnormalities. The hair follicles (HFs) are wrongly destroyed by the immune system in a condition known as Alopecia Areata and results in chronic non-cicatricial hair loss discernible by spherical patches. It’s a severely worsening or relapsing malady that can be permanent during severe falling out of hair. In …
