Is it normal to lose hair and how much?
Dr. Philip Abimelec: The growth of hair is a cyclical growth phase that lasts 2 to 5 years, a resting phase and fall that lasts about 3 months. It is normal to lose 30 hair per day but the falls twice in autumn and spring, the fall season. But one gets the impression of hair loss much greater when you do not wash their hair every day. We must not only assess the importance of hair loss but also the daily average capillary density, volume and the maximum length of the hair.Women are aware of hair loss as they lose volume, the diameter of the ring which allows the tie in a pony tail becomes smaller.
What is telogen effluvium?
Dr. Philip Abimelec: The telogen effluvium is a hair loss diffuse large (the gentle traction of a lock of hair back over five hair ) and transient. This effluvium occurs normally in the weeks after birth and may persist for several months. The telogen effluvium can also occur after a high fever, an operation under general anesthesia or certain medications (antidepressants or anti-cholesterol, for example). Another frequent cause is the cessation of the contraceptive pill.
What androgenic alopecia?
Dr. Philip Abimelec: male androgenic alopecia occurs most often by a hair loss that predominates in the gulfs (temples) and the top of the skull, but there are more diffuse forms. The female androgenic alopecia typically results in a hair loss diffuse, localized forms should be investigated, a hormonal disorder. The dominant female pattern baldness on top of the skull more or less in the rear, it will first notice a decrease in the volume and length but also by a hair texture that is changing, with adiamètre diminué et une longueur réduite. L'alopécie androgénique est d'origine génétique et hormonale, avec une susceptibilité particulière des cheveux sur le sommet du crâne. A noter que l'importance de l'alopécie androgénique est variable selon les personnes, allant de formes discrètes à sévères. Elle évolue souvent par poussées avec des périodes où l'on perd plus ses cheveux. Chez tout le monde, la perte des cheveux s'accentue avec l'avancée en âge. C'est ainsi qu'un homme sur deux a des golfes dégarnis à 50 ans.
How to ask the dermatologist he diagnosed?
Dr. Philip Abimelec: The combination of hair loss chronic predominant on the top of the skull, located in humans or diffuse in women, over time, with the presence of small fine hair and a family history to suspect strongly diagnosis. We must rule out other causes of hair loss that can diffuse also associated with androgenic alopecia (change of pill, high fever, endocrine disorders, iron deficiency or vitamin B12, drug taking?). A blood sample is often necessary, especially among women. Trichogramma to confirm the presumptive diagnosis in difficult cases or diffuse alopecia areata is suspected. Scales used to quantify the importance of hair loss . In humans, we use the classification of Hamilton and Norwood in women's classification or Ludwig Savin. Several causes of falls can coexist, especially among women. Androgenic alopecia may be aggravated by telogen effluvium related to iron deficiency, a dysfunction of the thyroid or a deficiency in vitamin B12 (in case of strict dieting, eating disorders, malnutrition or pernicious anemia) etc.. Overall, when one is faced with alopecia, eliminate the most common cause which is the normal seasonal decline. There are other rarer drops diffuse as anagen effluvium. This form is often obvious because the hair loss is abundant, the anagen effluvium occurs within or alopecia areata in the aftermath of chemotherapy. Also include scarring alopecia that are often associated with inadequate care for women with curly hair (braided flat, blow dry, hot irons, bun?) Or rare diseases (cicatricial folliculitis, lichen planus pilaris, lupus erythematosus). It should also include trichotillomania (habit of rubbing, pulling or tearing of hair) which can cause a hair loss diagnosis difficult.
When to worry, when to consult?
Dr. Philip Abimelec: In the presence of hair loss seems excessive, try to see if a loss of volume, length or density can be objectified. It should be reassured to know before a fall seasonal worries. If there is an obvious cause of a fall and abrupt (pregnancy, stopping a pill, recent surgery, chemotherapy), we must know wait several months to observe regrowth. When hair loss is chronic, you lose your hair gradually and we do not notice that when the hair is divided by two. From that moment, the person noticed this and think that this phenomenon has happened suddenly. So beware of false impressions! The existence of family history pushes control to the dermatologist to objectify androgenic alopecia whose support allows rapid stabilization. Faced with diffuse alopecia, dermatologist may deem necessary sometimes to make a little checkup to eliminate iron deficiency or a thyroid problem. The best advice dermatologist sufferers of alopecia areata or alopecia cicatricial rarer. Patients who use improper care must try to change their habits before considering treatment.
