Causes oh hair loss in men and women

  1. 1. ==== ====hair loss facts for men and women, check the ====Hair loss is related to the tendency of hair follicles to stop producing hair growth. Partial orcomplete loss of hair is called alopecia. Hair loss usually develops gradually and may be patchy ordiffuse.Interesting Facts About Hair And Hair LossHair is the fastest growing tissue in the body, second only to bone marrow. The average scalp contains about 100,000 hairs. Roughly 100 hairs are lost from your head every day. Each individual hair survives for an average of 4 - 7 years, during which time it grows about halfan inch a month. You need to lose about 50% of your hair before hair loss becomes noticeable. In the United States, 30 million women experience hereditary hair loss. 70% of women withthinning hair can attribute it to hereditary hair loss. Hereditary hair loss or androgenetic alopecia is the most common form of hair loss for men,representing more than 95% of all male cases. Androgenetic alopecia affects many more men than women. About two-thirds of men experiencesome degree of appreciable hair loss by the time they are 35 years old, and about 85% havesignificantly thinning hair by age 50. In the United States, there has not been an elected bald President since the television age began.The Most Common Cause Of Hair LossThe most common cause of hair loss is genetics - inherit the tendency to lose hair from either orboth of parents. The medical term for the genetic predisposition for hair loss is "androgeneticalopecia".In androgenetic alopecia, the genes affect how the hair grows. They trigger a sensitivity to a classof hormones called androgens, including testosterone, which causes hair follicles (which hairgrows from) to shrink. Shrinking follicles produce thinner hair and eventually none at all. Thus,androgenetic alopecia is caused by the bodys failure to produce new hairs and not by excessivehair loss. Heredity also affects the age at which you begin to lose hair and the developmentalspeed, pattern and extent of your baldness.Androgenetic alopecia accounts for more than 95% of hair loss in men. By the age of 35 two-thirdsof American men will experience some degree of appreciable hair loss and by the age of 50approximately 85% of men have significantly thinning hair.
  2. 2. Men generally develop bald spots on the forehead area or on the top of the head. In men, thehairs on the top of the head have a genetic sensitivity to the male hormone testosterone while thehairs on the sides and back of the head do not possess this genetic trait and therefore are notaffected. For this reason hairs removed from the sides and the back (donor hair) will maintain theirgenetic predisposition when transplanted and continue to grow when moved to the top of the headwhere hair loss has occurred.For woman, female pattern baldness is the most common type of hair loss. It can begin at puberty,but is most often seen after menopause. Women have an overall thinning of the hair throughoutthe scalp while the frontal hairline generally remains intact.Other Hair Loss Causes And Risk FactorsHair loss is not usually caused by a disease, but is related to aging, heredity, and testosterone. Inaddition to the common male and female patterns from a combination of these factors, otherpossible causes of hair loss, especially if in an unusual pattern exists, include:Side effects of medications or medical treatments. Certain drugs used to treat gout, arthritis,depression, heart problems and high blood pressure may cause hair loss in some people. Drugsthat can cause hair loss include:cholesterol lowering drugs: clofibrate, gemfibrozil parkinson medications: levodopa ulcer drugs: cimetidine, ranitidine anticoagulants: coumarin, heparin medications for gout: allopurinol antiarthritics: penicillamine, auranofin, indomethacin, naproxen, sulindac, methotrexate drugs derived from vitamin-A: isotretinoin, etretinate anticonvulsants: trimethadione antidepressants: tricyclics, amphetamines beta blockers: atenolol, metoprolol, nadolol, propranolol antithyroid agents: carbimazole, Iodine, thiocyanate, thiouracilDelayed shedding from stress. This common form of hair loss happens two to three months after amajor body stress. The stressful event induces a higher proportion of hair follicles to enter theresting stage all at the same time. A few months later, all of the now-resting follicles begin to shedtheir hairs at about the same time. Because the stressful event happened months ago, mostpeople do not connect it with their hair loss. It is a temporary condition, and new hairs begingrowing within a few months. Stress can also trigger genetic hair loss. If your already losing hairstress will cause you to lose hair even faster.Inadequate protein in diet. Some people who go on crash diets that are low in protein, or haveseverely abnormal eating habits, may develop protein malnutrition. The body will save protein byshifting growing hairs into the resting phase. Massive hair shedding can occur two to three monthslater. This condition can be reversed and prevented by eating the proper amount of protein and,when dieting, maintaining adequate protein intake.
  3. 3. Iron deficiency. Iron deficiency occasionally produces hair loss. Iron deficiency is common towomen during menstruation and pregnancy and can be corrected through proper diet or ironsupplements.Pregnancy and childbirth. Hair loss that is connected to pregnancy usually occurs after delivery.When a woman is pregnant, her hairs grow at very high speed. However, after a woman deliversher baby, many hairs enter the resting phase of the hair cycle. This is a natural process andresolves completely in most cases.Birth control pills. Women who lose hair while taking birth control pills usually have an inheritedtendency for hair thinning (androgenic alopecia). If hair thinning occurs, a woman can consult hergynecologist about switching to another birth control pill. If a woman has a history of femalepattern loss in her family she should advise her doctor before going on the pill.Scalp infection. Infections such as ringworm can invade the hair and skin of your scalp, leading tohair loss. Once infections are treated, hair generally regrows.Thyroid disease. Both an overactive thyroid and an underactive thyroid can cause hair loss. Hairloss associated with thyroid disease can be reversed with proper treatment.Patchy hair loss (Alopecia areata). Alopecia areata is classified as an autoimmune disease, butthe cause is unknown. This disorder causes hair follicles to stop producing hairs. Approximately2% of all people experience an episode of alopecia areata at some point in their lives. In the vastmajority of cases the condition is temporary and goes away all by itself within 6-7 months, and hairgrowth in the bald patch resumes.Hair pulling (traction alopecia). Traction alopecia is the loss of hair from constant pulling, often theresult of tightly braided hair styles.Hair care. Pulling your hair back too tightly can cause hair loss. You may lose hair around theedge of the hairline, especially around the face and forehead. Using curling irons or dyescontinually can also result in hair loss. Hair usually grows back when these activities are stopped.Blow-drying can worsen hair loss. The reason is that extreme heat damages the proteins in thehairs making them fragile and liable to break off. Brushing the hair during blow-drying causes moredamage. If you use a hair dryer, it should be set on the coolest setting. Hair dyes, perms andhairsprays do not affect thinning hair.Age. As you age, your hairs tend to break more easily, and hair follicles do not grow as much hair.Yury Bayarski is the author of - website, offering patches and natural healthproducts.
