Traction Alopecia
Traction alopecia is a type of alopecia or hair loss caused by a chronic pulling force being applied to the hair. It commonly results from a person frequently wearing their hair in a particularly tight ponytail, pigtails, or braids with increased odds when hair is chemically relaxed as this compromises the hair shaft's tensile strengt resulting in hair breakage. Traction alopecia causes a recession of the hairline due to chronic traction, which is characterized by a fringe along the marginal hairline on physical exam. Diagnosis is clinical and treatment directed at cessation of the chronic traction, while cosmesis, cosmeses, with surgical restoration is reserved for severe cases with scarring fibrosis. Cause * Traumatic hairstyle. It is commonly seen with certain hair styles like a particularly tight ponytail, pigtails, braid or braiding pattern that pulls the hairline forcefully towards the vertex of the scalp, and has been reported more often in African American women (as some we ...

Alopecia
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 defici ...

Sikh
Sikhs ( or ; pa, ਸਿੱਖ, ' ) are people who adhere to Sikhism, Sikhism (Sikhi), a Monotheism, monotheistic religion that originated in the late 15th century in the Punjab region of the Indian subcontinent, based on the revelation of Guru Nanak. The term ''Sikh'' has its origin in the word ' (), meaning 'disciple' or 'student'. Male Sikhs generally have ''Singh'' ('lion'/'tiger') as their last name, though not all Singhs are necessarily Sikhs; likewise, female Sikhs have ''Kaur'' ('princess') as their last name. These unique last names were given by the Gurus to allow Sikhs to stand out and also as an act of defiance to India's caste system, which the Gurus were always against. Sikhs strongly believe in the idea of "Sarbat Da Bhala" - "Welfare of all" and are often seen on the frontline to provide humanitarian aid across the world. Sikhs who have undergone the ''Amrit Sanchar'' ('baptism by Khanda (Sikh symbol), Khanda'), an initiation ceremony, are from the day of thei ...

List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm th ...

Cicatricial Alopecia
Scarring hair loss, also known as cicatricial alopecia, is the loss of hair which is accompanied with scarring. This is in contrast to non scarring hair loss. It can be caused by a diverse group of rare disorders that destroy the hair follicle, replace it with scar tissue, and cause permanent hair loss. A variety of distributions are possible.Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). Page 647. McGraw-Hill. . In some cases, hair loss is gradual, without symptoms, and is unnoticed for long periods. In other cases, hair loss is associated with severe itching, burning and pain and is rapidly progressive. The inflammation that destroys the follicle is below the skin surface and there is usually no "scar" seen on the scalp. Affected areas of the scalp may show little signs of inflammation, or have redness, scaling, increased or decreased pigmentation, pustules, or draining sinuses. Scarring hair loss occurs in otherwise healthy people of al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Croydon Facelift
In English slang, a Croydon facelift (sometimes council house facelift, or in Northern Ireland a Millie facelift) is a particular hairstyle worn by some women. The hair is pulled back tightly and tied in a bun or ponytail at the back. The supposed result is that the skin of the forehead and face are pulled up and back, producing the effects of a facelift. Traction alopecia, a type of gradual hair loss, can result from hairstyles that tightly pull the hair in this manner.James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. . This hairstyle is frequently portrayed in the media as belonging to young women from the lower social classes, particularly the Chav subculture ('' Ned'' in Scotland, ''Millie'' in Northern Ireland). The term is thus considered derogatory because it portrays people from Croydon as being lower class. ''Croydon'' can be replaced by the name of any other unfashionable residential area. ...

Frontal Fibrosing Alopecia
Frontal fibrosing alopecia is the frontotemporal hairline recession and eyebrow loss in postmenopausal women that is associated with perifollicular erythema, especially along the hairline.Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). McGraw-Hill. . It is considered to be a clinical variant of lichen planopilaris. Presentation There is loss of both terminal and vellus hairs that occurs in a bandlike pattern on the frontotemporal scalp. It is a scarring alopecia that has been associated with facial papules, glabellar red dots, a loss of eyebrows, and prominent venous vasculature in the forehead. Facial hyperpigmentation may occur in dark-skinned patients if association with lichen planus pigmentosus is present. Associations Frontal fibrosing alopecia has been most often reported in post-menopausal women with higher levels of affluence and a negative smoking history. Autoimmune disease is found in 30% of patients. Pathogenesis Alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alopecia Areata
Alopecia areata, also known as spot baldness, is a condition in which hair is lost from some or all areas of the body. Often, it 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 ('' alopecia totalis''), or all body hair is lost (''alopecia universalis''). Hair loss can be permanent, or temporary. It is distinct from pattern hair loss, which is common among males. Alopecia areata is believed to be an autoimmune disease resulting from a breach in the immune privilege of the hair follicles. Risk factors include a family history of the condition. Among identical twins, if one is affected, the other has about a 50% chance of also being affected. The underlying mechanism involves failure by the body to recognize i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichotillomania
Trichotillomania (TTM), also known as hair-pulling disorder or compulsive hair pulling, is a mental disorder characterized by a long-term urge that results in the pulling out of one's own hair. A brief positive feeling may occur as hair is removed. Efforts to stop pulling hair typically fail. Hair removal may occur anywhere; however, the head and around the eyes are most common. The hair pulling is to such a degree that it results in distress and hair loss can be seen. The disorder may run in families. It occurs more commonly in those with obsessive compulsive disorder. Episodes of pulling may be triggered by anxiety. People usually acknowledge that they pull their hair, and broken hairs may be seen on examination. Other conditions that may present similarly include body dysmorphic disorder; however, in that condition people remove hair to try to improve what they see as a problem in how they look. Treatment is typically with cognitive behavioral therapy. The medication clom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential Diagnosis
In healthcare, a differential diagnosis (abbreviated DDx) is a method of analysis of a patient's history and physical examination to arrive at the correct diagnosis. It involves distinguishing a particular disease or condition from others that present with similar clinical features. Differential diagnostic procedures are used by clinicians to diagnose the specific disease in a patient, or, at least, to consider any imminently life-threatening conditions. Often, each individual option of a possible disease is called a differential diagnosis (e.g., acute bronchitis could be a differential diagnosis in the evaluation of a cough, even if the final diagnosis is common cold). More generally, a differential diagnostic procedure is a systematic diagnostic method used to identify the presence of a disease entity where multiple alternatives are possible. This method may employ algorithms, akin to the process of elimination, or at least a process of obtaining information that shrinks the "p ...

Hijab
In modern usage, hijab ( ar, حجاب, translit=ḥijāb, ) generally refers to headcoverings worn by Muslim women. Many Muslims believe it is obligatory for every female Muslim who has reached the age of puberty to wear a head covering. While such headcoverings can come in many forms, hijab often specifically refers to a cloth wrapped around the head, neck and chest, covering the hair and neck but leaving the face visible. The term was originally used to denote a partition, a curtain, or was sometimes used for the Islamic rules of modesty. This is the usage in the verses of the Qur'an, in which the term ''hijab'' sometimes refers to a curtain separating visitors to Muhammad's main house from his wives' residential lodgings. This has led some to claim that the mandate of the Qur'an applied only to the wives of Muhammad, and not to the entirety of women. Another interpretation can also refer to the seclusion of women from men in the public sphere, whereas a metaphysical dimens ...

Kesh (Sikhism)
In Sikhism, kesh (sometimes kes) (Gurmukhi: ਕੇਸ) is the practice of allowing one's hair to grow naturally out of respect for the perfection of God's creation. The practice is one of The Five Kakaars, the outward symbols ordered by Guru Gobind Singh in 1699 as a means to profess the Sikh faith. The hair is combed twice daily with a kanga, another of the five Ks, and tied into a simple knot known as a ''joora'' or ''rishi knot''. This knot of hair is usually held in place with the kanga and covered by a turban. The 52 commands of Guru Gobind Singh written at Hazur Sahib at Nanded in the state of Maharashtra, mention that the kesh (hair) should be revered as the form of the Satguru (eternal guru) whom they consider as the same as god. For this reason by practitioners they are kept with the utmost respect. This includes regular maintenance of hair which includes but is not limited to combing at least twice daily, washing regularly and not allowing for public touching. Signifi ...

Wig (hair)
A wig is a head or hair accessory made from human hair, animal hair, or synthetic fiber. The word wig is short for periwig, which makes its earliest known appearance in the English language in William Shakespeare's ''The Two Gentlemen of Verona''. Some people wear wigs to disguise baldness; a wig may be used as a less intrusive and less expensive alternative to medical therapies for restoring hair or for a religious reason. History Ancient and medieval use In Egyptian society men and women commonly had clean shaven or close cropped hair and often wore wigs. The ancient Egyptians created the wig to shield shaved, hairless heads from the sun. They also wore the wigs on top of their hair using beeswax and resin to keep the wigs in place. Wealthy Egyptians would wear elaborate wigs and scented head cones of animal fat on top of their wigs. Other ancient cultures, including the Assyrians, Phoenicians, Jews in ancient Israel, Greeks and Romans, also used wigs as an everyday fashion. ...
