Hair Transplant Surgery
Hair transplantation is a surgical technique that removes hair follicles from one part of the body, called the 'donor site', to a bald or balding part of the body known as the 'recipient site'. The technique is primarily used to treat male pattern baldness. In this minimally invasive procedure, grafts containing hair follicles that are genetically resistant to balding (like the back of the head) are transplanted to the bald scalp. Hair transplantation can also be used to restore eyelashes, eyebrows, beard hair, chest hair, pubic hair and to fill in scars caused by accidents or surgery such as face-lifts and previous hair transplants. Hair transplantation differs from skin grafting in that grafts contain almost all of the epidermis and dermis surrounding the hair follicle, and many tiny grafts are transplanted rather than a single strip of skin. Since hair naturally grows in groupings of 1 to 4 hairs, current techniques harvest and transplant hair "follicular units" in their ...

Hidradenitis Suppurativa
Hidradenitis suppurativa (HS), sometimes known as acne inversa or Verneuil's disease, is a long-term dermatological condition characterized by the occurrence of inflamed and swollen lumps. These are typically painful and break open, releasing fluid or pus. The areas most commonly affected are the underarms, under the breasts, and the groin. Scar tissue remains after healing. HS may significantly limit many everyday activities, for instance, walking, hugging, moving, and sitting down. Sitting disability may occur in patients with lesions in sacral, gluteal, perineal, femoral, groin or genital regions; and prolonged periods of sitting down itself can also worsen the condition of the skin of these patients. The exact cause is usually unclear, but believed to involve a combination of genetic and environmental factors. About a third of people with the disease have an affected family member. Other risk factors include obesity and smoking. The condition is not caused by an infecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Follicular Unit Transplantation
Follicular unit transplantation (FUT) is a hair restoration technique, also known as the strip procedure, where a patient's hair is transplanted in naturally occurring groups of 1 to 4 hairs, called follicular units. Follicular units also contain sebaceous (oil) glands, nerves, a small muscle, and occasional fine vellus hairs. In follicular unit transplantation, these small units allow the surgeon to safely transplant thousands of grafts in a single session, which maximizes the cosmetic impact of the procedure.Orentreich N: Autografts in alopecias and other selected dermatological conditions. Annals of the New York Academy of Sciences 83:463-479, 1959. FUT is considered an advance over older hair transplantation procedures that used larger grafts and often produced a pluggy, unnatural look. In a properly-performed follicular unit transplant, the results will mimic the way hair grows in nature and will be undetectable as a hair transplant. In recent history, FUT had been the most ...

Cosmetic Surgery
Plastic surgery is a surgical specialty involving the restoration, reconstruction or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosmetic surgery. Reconstructive surgery includes craniofacial surgery, hand surgery, microsurgery, and the treatment of burns. While reconstructive surgery aims to reconstruct a part of the body or improve its functioning, cosmetic (or aesthetic) surgery aims at improving the appearance of it. Etymology The word ''plastic'' in ''plastic surgery'' means "reshaping" and comes from the Greek πλαστική (τέχνη), ''plastikē'' (''tekhnē''), "the art of modelling" of malleable flesh. This meaning in English is seen as early as 1598. The surgical definition of "plastic" first appeared in 1839, preceding the modern "engineering material made from petroleum" sense by 70 years. History Treatments for the plastic repair of a broken nose are first mentioned in the Egyptian medical text ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

External Links
An internal link is a type of hyperlink on a web page to another page or resource, such as an image or document, on the same website or domain. Hyperlinks are considered either "external" or "internal" depending on their target or destination. Generally, a link to a page outside the same domain or website is considered external, whereas one that points at another section of the same web page or to another page of the same website or domain is considered internal. These definitions become clouded, however, when the same organization operates multiple domains functioning as a single web experience, e.g. when a secure commerce website is used for purchasing things displayed on a non-secure website. In these cases, links that are "external" by the above definition can conceivably be classified as "internal" for some purposes. Ultimately, an internal link points to a web page or resource in the same root directory. Similarly, seemingly "internal" links are in fact "external" for ...

Hair Cloning
Hair multiplication or hair cloning is a proposed technique to counter hair loss. The technology to clone hair is in its early stages. Experts previously assumed that in the case of complete baldness, follicles are completely absent from the scalp, so they cannot be regenerated. However, it was discovered that the follicles are not entirely absent, as there are stem cells in the bald scalp from which the follicles naturally arise. Abnormal behavior of these follicles is suggested to be the result of progenitor cell deficiency in these areas. The basic idea of hair cloning is that healthy follicle cells or dermal papillae can be extracted from the subject from areas that are not bald and are not suffering hair loss. They can be multiplied (cloned) by various culturing methods and the new cells can be injected back in the bald scalp, where they would produce healthy hair. In 2015, initial trials for human hair were successful in generating new follicles, but the hairs grew in vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grafts
Grafting refers to a surgical procedure to move tissue from one site to another on the body, or from another creature, without bringing its own blood supply with it. Instead, a new blood supply grows in after it is placed. A similar technique where tissue is transferred with the blood supply intact is called a flap. In some instances, a graft can be an artificially manufactured device. Examples of this are a tube to carry blood flow across a defect or from an artery to a vein for use in hemodialysis. Classification Autografts and isografts are usually not considered as foreign and, therefore, do not elicit rejection. Allografts and xenografts may be recognized as foreign by the recipient and rejected. * Autograft: graft taken from one part of the body of an individual and transplanted onto another site in the same individual, e.g., skin graft. * Isograft: graft taken from one individual and placed on another individual of the same genetic constitution, e.g., grafts between i ...

Norman Orentreich
Norman Orentreich (; December 26, 1922 – January 23, 2019) was a New York dermatologist and the father of modern hair transplantation. Orentreich created Estee Lauder Companies' Clinique line of skin care products, invented a number of dermatologic procedures and was the first president of the American Society for Dermatologic Surgery. He is the founder of the Orentreich Medical Group and the Orentreich Foundation for the Advancement of Science, and the co-director of the latter organization. Hair transplantation The New York Academy of Medicine cited Orentreich's early research, as a young man, as being critical to later developments in hair transplantation: While at NYU’s Skin and Cancer hospital, Norman focused his clinical research on patients with hair loss, making use of small scalp skin grafts to better understand the pathophysiology of these diverse conditions. This led to the establishment of the theory of donor and recipient dominance, making it surgically possib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dermatologist
Dermatology is the branch of medicine dealing with the skin.''Random House Webster's Unabridged Dictionary.'' Random House, Inc. 2001. Page 537. . It is a speciality with both medical and surgical aspects. A dermatologist is a specialist medical doctor who manages diseases related to skin, hair, nails, and some cosmetic problems. Etymology Attested in English in 1819, the word "dermatology" derives from the Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία '' -logia''. Neo-Latin ''dermatologia'' was coined in 1630, an anatomical term with various French and German uses attested from the 1730s. History In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases ( Alibert's, 1806–1816) appeared in print around the same time.Freedberg, et al.

Baldness
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. Common types include male- or female-pattern hair loss, alopecia areata, and a thinning of hair known as telogen effluvium. The cause of male-pattern hair loss is a combination of genetics and male hormones; the cause of female pattern hair loss is unclear; the cause of alopecia areata is autoimmune; and the cause of telogen effluvium is typically a physically or psychologically stressful event. Telogen effluvium is very common following pregnancy. Less common causes of hair loss without inflammation or scarring include the pulling out of hair, certain medications including chemotherapy, HIV/AIDS, hypothyroidism, and malnutrition including iron deficienc ...

Eyebrows
An eyebrow is an area of short hairs above each eye that follows the shape of the lower margin of the brow ridges of some mammals. In humans, eyebrows serve two main functions: first, communication through facial expression, and second, prevention of sweat, water, and other debris from falling down into the eye socket. It is common for people to modify their eyebrows by means of hair removal and makeup. Functions A number of theories have been proposed to explain the function of the eyebrow in humans. One approach suggests its main function is to prevent moisture (mostly sweat and rain) from flowing into the eye. Another theory holds that clearly visible eyebrows provided safety from predators when early hominid groups started sleeping on the ground. Recent research, however, suggests eyebrows in humans developed as a means of communication and that this is their primary function. Humans developed a smooth forehead with visible, hairy eyebrows capable of a wide range of movemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Favus
Favus (Latin for "honeycomb") or tinea favosa is the severe form of tinea capitis, a skin infectious disease caused by the dermatophyte fungus ''Trichophyton schoenleinii.'' Typically the species affects the scalp, but occasionally occurs as onychomycosis, tinea barbae, or tinea corporis. The word ''favid'' is more used than French word ''favus'', which is close to the Latin etymology. Presentation The uncomplicated appearance is that of a number of yellowish, circular, cup-shaped crusts (scutulum or shield) grouped in patches like a honeycomb, each crust about the size of a split pea, with a bundle of hair projecting in the center. These increase in size and become crusted over, so that the characteristic lesion can only be seen round the edge of the scab. A mousy odour is often present. Growth continues to take place for several months, when scab and scutulum go away, leaving a shining bare patch destitute of hair. The disease is essentially chronic, lasting from ten to twenty ...
