[7] Her major contributions to international medicine include research related to various aspects of hair diseases. [8] [9] A new hair disorder described by Tosti [10] is often referred to as "Tosti Alopecia". [11]
Tosti is the author or co-author of several dermatological monographs and book chapters,[ citation needed ] including an e-medicine chapter about contact stomatitis. [12] Topics of books she has authored include fungal nail infections (onychomycosis).
Tosti is the author of nearly 700 scientific publications, 600 peer-reviewed papers and the editor or co-editor of 30 books. [13] She is a secretary and treasurer of the North American Hair Research Society and of the World Trichoscopy Society. Tosti is a mentee of the Women's Dermatologic Society mentorship award and has presented at conferences and lectures in more than 20 different countries.

Alopecia areata, also known as spot baldness, is a condition in which hair is lost from some or all areas of the body. It often results in a few bald spots on the scalp, each about the size of a coin. Psychological stress and illness are possible factors in bringing on alopecia areata in individuals at risk, but in most cases there is no obvious trigger. People are generally otherwise healthy. In a few cases, all the hair on the scalp is lost, or all body hair is lost. Hair loss can be permanent, or temporary.
Hair loss, also known as alopecia or baldness, refers to a loss of hair from part of the head or body. Typically at least the head is involved. The severity of hair loss can vary from a small area to the entire body. Inflammation or scarring is not usually present. Hair loss in some people causes psychological distress.
Alopecia universalis(AU), also known as alopecia areata universalis, is a medical condition involving the loss of all body hair, including eyebrows, eyelashes, chest hair, armpit hair, and pubic hair. It is the most severe form of alopecia areata (AA). People with the condition are usually healthy and have no other symptoms and a normal life expectancy.
The management of hair loss, includes prevention and treatment of alopecia, baldness, and hair thinning, and regrowth of hair.
Trichology is the study of the hair and scalp. The term derives from Ancient Greek θρίξ (thríx), "hair" and -λογία -logia. In most jurisdictions the title of a trichologist, not the field of trichology, is considered a para-medical discipline.
Dermatoscopy, also known as dermoscopy or epiluminescence microscopy, is the examination of skin lesions with a dermatoscope. It is a tool similar to a camera to allow for inspection of skin lesions unobstructed by skin surface reflections. The dermatoscope consists of a magnifier, a light source, a transparent plate and sometimes a liquid medium between the instrument and the skin. The dermatoscope is often handheld, although there are stationary cameras allowing the capture of whole body images in a single shot. When the images or video clips are digitally captured or processed, the instrument can be referred to as a digital epiluminescence dermatoscope. The image is then analyzed automatically and given a score indicating how dangerous it is. This technique is useful to dermatologists and skin cancer practitioners in distinguishing benign from malignant (cancerous) lesions, especially in the diagnosis of melanoma.
Monilethrix is a rare autosomal dominant hair disease that results in short, fragile, broken hair that appears beaded. It comes from the Latin word for necklace (monile) and the Greek word for hair (thrix). Hair becomes brittle, and breaks off at the thinner parts between the beads. It appears as a thinning or baldness of hair and was first described in 1897 by Walter Smith
Pili torti is characterized by short and brittle hairs that appear flattened and twisted when viewed through a microscope.
Erosive pustular dermatitis of the scalp presents with pustules, erosions, and crusts on the scalp of primarily older Caucasian females, and on biopsy, has a lymphoplasmacytic infiltrate with or without foreign body giant cells and pilosebaceous atrophy.
Kinking hair, or acquired progressive kinking of hair, is a skin condition primarily reposted in postpubescent males with androgenetic alopecia, presenting with gradual curling and darkening of the frontal, temporal, auricular, and vertex hairs which, under the microscope, show kinks and twists with or without longitudinal grooving.
Pressure alopecia, also known as postoperative alopecia, and pressure-induced alopecia, occurs in adults after prolonged pressure on the scalp during general anesthesia, with the head fixed in one position, and may also occur in chronically ill persons after prolonged bed rest in one position that causes persistent pressure on one part of the scalp, all likely due to pressure-induced ischemia.
Blue nails, or more formally azure lunula, are characterized by a blue discoloration of the lunulae, seen in argyria and cases of hepatolenticular degeneration, also having been reported in hemoglobin M disease and hereditary acrolabial telangiectases.
Spotted lunulae is a distinctive change that occurs with alopecia areata.
Melanonychia is a black or brown pigmentation of a nail, and may be present as a normal finding on many digits in Afro-Caribbeans, as a result of trauma, systemic disease, or medications, or as a postinflammatory event from such localized events as lichen planus or fixed drug eruption.
Pili annulati is a genetic trait in which the hair seems 'banded' by alternating segments of light and dark color when seen in reflected light.
Trichoscopy is a method of hair and scalp evaluation and is used for diagnosing hair and scalp diseases. The method is based on dermoscopy. In trichoscopy hair and scalp structures may be visualized at many-fold magnification. Currently magnifications ranging from 10-fold to 70-fold are most popular in research and clinical practice.
Lidia Rudnicka is a Polish-American dermatologist with contributions to the field of scleroderma research, hair diseases and melanoma prevention.
Frontal fibrosing alopecia is the frontotemporal hairline recession and eyebrow loss in postmenopausal women that is associated with perifollicular erythema, especially along the hairline. It is considered to be a clinical variant of lichen planopilaris.
Short anagen syndrome is a condition where hair does not grow beyond a short length, due to an unusually short duration of active hair growth. Most cases are associated with fine blond hair.
Frictional alopecia is the loss of hair that is caused by rubbing of the hair, follicles, or skin around the follicle. The most typical example of this is the loss of ankle hair among people who wear socks constantly for years. The hair may not grow back even years after the source of friction has ended.
