Ludwig Scale
The Ludwig scale is a method of classifying female pattern baldness (androgenic alopecia), and ranges from stages I to III. Stage I begins with thinning on the top of the head. In stage II the scalp starts to show. All of the hair at the crown of the head may be lost when the hair loss progresses to stage III. However, the scale is used merely for general categorization. Many women do not actually fit into the Ludwig stages. See also * Hamilton–Norwood scale for male pattern baldness References Medical scales Dermatologic terminology Trichology {{dermatology-stub ...

Female Pattern Baldness
Pattern hair loss (also known as androgenetic alopecia (AGA)) is a hair loss condition that primarily affects the top and front of the scalp. In male-pattern hair loss (MPHL), the hair loss typically presents itself as either a receding front hairline, loss of hair on the crown and vertex of the scalp, or a combination of both. Female-pattern hair loss (FPHL) typically presents as a diffuse thinning of the hair across the entire scalp. The condition is caused by a combination of male sex hormones (balding never occurs in castrated men) and genetic factors. Some research has found evidence for the role of oxidative stress in hair loss, the microbiome of the scalp, genetics, and circulating androgens; particularly dihydrotestosterone (DHT). Men with early onset androgenic alopecia (before the age of 35) have been deemed the male phenotypic equivalent for polycystic ovary syndrome (PCOS). The cause in female pattern hair loss remains unclear; androgenetic alopecia for women is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamilton–Norwood Scale
The Hamilton–Norwood scale is used to classify the stages of male pattern baldness. It is a widely accepted and reproducible classification system for male pattern hair loss (androgenetic alopecia). The stages are described with a number from 1 to 7 with a type A variant for the cases with anterior involvement. Overview Androgenetic alopecia follows a defined pattern of hair loss, beginning with bitemporal recession of the frontal hairline. Eventually, diffuse thinning over the vertex (top) of the scalp occurs. With progression, complete hair loss in this region is common. The bald patch progressively enlarges and eventually joins the receding frontal hairline. This measurement scale was first introduced by James Hamilton in the 1950s and later revised and updated by O'Tar Norwood in the 1970s. It is sometimes referred to as the Norwood–Hamilton scale or simply the Norwood scale. The scale is regularly used by doctors to assess the severity of baldness, but it is not cons ...

Medical Scales
Medicine is the science and practice of caring for patients, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of creativity and skill), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
