Hair loss usually develops gradually and may be patchy or all over (diffuse). You lose roughly 100 hairs from your head every day. The average scalp contains about 100,000 hairs. Both men and women tend to lose hair thickness and amount as they age. Baldness is not usually caused by a disease. It is related to aging, heredity, and changes in the hormone, testosterone. Inherited or “pattern baldness” affects many more men than women. About one-half of men begin to bald by the time they are 30 years old, and most are either bald or have a balding pattern by age 60.
Acne keloidalis (also known as “Acne keloidalis” and “Nuchal keloid acne” is a destructive scarring folliculitis that occurs almost exclusively on the occipital scalp of people of African descent, primarily men. This is mainly because men often cut their hair very low as opposed to women, allowing the hair to prick the occipital scalp and upset it. Acne keloidalis nuchae most commonly presents itself in individuals aged 13 to 25.
Alopecia Areata is a medical condition in which hair is lost from some or all areas of the body usually from the scalp. Because it causes bald spots on the scalp, especially in the first stages it is sometimes called spot baldness. In 1–2% of cases, the condition can spread to the entire scalp (Alopecia totalis) or to the entire epidermis (Alopecia universalis). Conditions resembling AA, & having a similar cause, occur also in other species.
Anagen effluvium is the pathologic loss of anagen or growth-phase hairs. Classically, it is caused by radiation therapy to the head and systemic chemotherapy, especially with alkylating agents.
Androgenic Alopecia Men…..
Androgenic alopecia (also known as androgenetic alopecia or alopecia androgenetica) is the most common cause of hair loss and thinning in humans. Variants appear in both men & women. Androgenic alopecia also occurs in chimpanzees and orangutans. In humans, this condition is also commonly known as male pattern baldness. In classic pattern baldness, hair is lost in a well-defined pattern, beginning above both temples. Hair also thins at the crown of the head. Often a rim of hair around sides & rear of the head is left.
Androgenic Alopecia Women…..
Androgenic alopecia (also known as androgenetic alopecia or alopecia androgenetica) is the most common cause of hair loss and thinning in humans. Variants appear in both men & women. Women do not suffer classic male pattern baldness, instead the hair becomes thinner around the whole scalp, and the hairline does not recede. This is dubbed “female pattern baldness” and may occur in males. This variety of androgenic alopecia in women rarely leads to total baldness.
A chronic inflammatory condition limited to the skin, caused by an autoimmune disease. An autoimmune disease occurs when the body’s tissues are attacked by its own immune system. Patients with lupus have unusual antibodies in their blood that are targeted against their own body tissues. Lupus can cause disease of skin, heart, lungs, kidneys, joints & nervous system. When only skin is involved, as mentioned condition is called discoid lupus.
Perifolliculitis capitis abscedens et suffodiens (also known as “Perifolliculitis capitis abscedens et suffodiens of Hoffman,” “Dissecting folliculitis,” and “Dissecting cellulitis of the scalp”) is an inflammatory condition of the scalp that can lead to scarring alopecia, which begins with deep inflammatory nodules, primarily over occiput, that progresses to coalescing regions of boggy scalp.
It is a deeper a hereditary form of inflammatory folliculitis that affects the whole follicular structure. This may be an uncommon condition among Caucasians but is very much present among the black race. In general, folliculitis is also seen as a secondary infection relative to eczema and scabies and is often in patients who are also suffering with diabetes, obesity, or those with immune deficiency or problems.
Hirsutism or frazonism is the excessive hairiness on women in those parts of the body where terminal hair does not normally occur or is minimal – for example, a beard or chest hair. It refers to a male pattern of body hair (androgenic hair) and it is therefore primarily of cosmetic and psychological concern. Hirsutism is a symptom rather than a disease and may be a sign of a more serious medical condition, especially if it develops well after puberty.
Hot Comb Alopecia…..
Hot comb alopecia was first reported in the late 1960s as a scarring alopecia seen in black women who straightened their hair with hot combs for cosmetic purposes, developing characteristically on the crown and spreading peripherally to form a large oval area of partial hair loss.
An eyelash or simply lash is one of the hairs that grow at the edge of the eyelid. Eyelashes protect the eye from debris and perform some of the same function as whiskers do on a cat or a mouse in the sense that they are sensitive to being touched, thus providing a warning that an object (such as an insect or dust mite) is near the eye (which is then closed reflexively).
Lichen Planopilaris is a condition which usually affects the parts of the body that have hair. This condition may eventually lead to hair loss which may be permanent, it may also cause scarring and inflammation. This condition is usually evident after some given period of time in exposure to the above mentioned substances. This condition appears vas if you have pimples only in their case the pimple are reddish in colour and they are usually very itchy. This condition may also cause the skin to appear uneven and rough.
Monilethrix is an autosomal dominant disorder characterized by a beaded appearance of the hair due to periodic thinning of the shaft. The phenotype results in hair fragility and patchy dystrophic alopecia. The term monilethrix is derived from monile (Latin), which means necklace, and thrix (Greek), which means hair. This term indicates the resemblance of the hair to a string of beads or a necklace. Monilethrix is also known as nodose hair.
Pili annulati (also known as “Ringed hair) is a peculiar disease in which the hair seems banded by alternating segments of light and dark color when seen in reflected light. The name pili annulati refers to hair fiber with rings – sometimes called ringed hair. In pili annulati the hair fiber has alternating light and dark bands along its length like zebra stripes. Usually this hair defect is
most obvious in people with blond hair as dark hair obscures the light and dark band pattern.
Pili torti (also known as “Twisted hairs”) is characterized by short and brittle hairs that appear flattened and twisted when viewed through a microscope. Pili torti is a rare hair condition characterized by fragile hair. In pili torti hair has a flattened shaft with clusters of narrow twists at irregular intervals. Some cases are genetic while others are acquired.
Polytrichia is a rare malformation characterized by the presence of bifurcated or multiple divided hair matrices and papillae, giving rise to the formation of multiple hair shafts within the individual follicles.
Pseudopelade of Brocq (also known as “Alopecia cicatrisata”) is a flesh- to pink-colored, irregularly shaped alopecia that may begin in a moth-eaten pattern with eventual coalescence into larger patches of alopecia.
The inner or epidermic coat of the hair follicle is closely adherent to the root of the hair, and consists of two strata named respectively the outer and inner root sheaths.The outer root sheath corresponds with the stratum mucosum of the epidermis, and resembles it in the rounded form and soft character of its cells; at the bottom of the hair follicle these cells become continuous with those of the root of the hair.
Telogen effluvium is a scalp disorder characterized by thinning/shedding of hair resulting from the early entry of hairs into the telogen phase. Emotional or physiological stressful events may result in an alteration of the normal hair cycle. Telogen effluvium may be caused by eating disorders, fever, childbirth, chronic illness, major surgery, anemia, severe emotional disorders, crash diets, hypothyroidism, and drug.
Traction alopecia is a form of alopecia, or gradual hair loss, caused primarily by pulling force being applied to the hair. This commonly results from the sufferer frequently wearing his/her hair in a particularly tight ponytail, pigtails or braids.
Trichomycosis is a superficial bacterial colonization of the hair shafts in sweat gland–bearing areas, such as the armpits and the pubic area. It is a trivial disease of worldwide occurrence that is believed to be caused by the genus Corynebacteria (mostly Corynebacterium tenuis).
Trichorrhexis nodosa is a defect in the hair shaft characterized by thickening or weak points (nodes) that cause the hair to break off easily. This group of conditions contributes to the appearance of hair loss, lack of growth, and damaged-looking hair.
Trichotillomania, which is classified as an impulse control disorder is the compulsive urge to pull out one’s own hair leading to noticeable hair loss, distress, and social or functional impairment. It is often chronic and difficult to treat.
Tufted folliculitis presents with doll’s hair-like bundling of follicular units, and is seen in a wide range of scarring conditions including chronic staphylococcal infection, chronic lupus erythematosus, lichen planopilaris, Graham-Little syndrome, folliculitis decalvans, acne keloidalis nuchae, immunobullous disorders, and dissecting cellulitis.
Whit Hair at an Early Age…..
White hair that is growing in the front part of your head is where it comes from. In some cases, if people develop white hair at such a young age, then the highest chances are that they have inherited this trait. If indeed it is an inherited trait, then you should know right at the beginning that there is nothing much you can do about this problem. However, in a lot of cases, this also happens due to some sudden or extreme shock.
Dandruff is a common chronic scalp condition marked by itching and flaking of the skin on your scalp. Although dandruff isn’t contagious and is rarely serious, it can be embarrassing and sometimes difficult to treat. The good news is that dandruff usually can be controlled. More stubborn cases of dandruff often respond to medicated shampoos.
