Why are we losing hair?
The hair grows for about six years in women, lives a few days before entering the phase of death (called telogen) -which lasts several weeks to several months before the fall. We have about 100,000 hair on the skull, and we lose between 60 and 100 per day, which ensures renewal without loss of mass. But it happens that the hair begins to fall suddenly and diffuse way, exceeding this threshold of 100 per day -nextile to count, acute hair loss is noticeable, especially in the shower, explain the doctors. It can be due to many factors, without being pathological.
Thus, in the spring and even more in autumn, the hair falls like dead leaves. This seasonal fall, quite normal, corresponds to the hormonal repercussion of the variations of luminosity and does not exceed six weeks.
Maternity also has consequences on hair loss: artificially kept in the bulb during pregnancy, they are more numerous in the telogen phase with childbirth. One in two women is affected by postpartum alopecia. Do not panic: we find its hair capital in the year.
Passage hair loss: how to prevent it?
We can not stop the natural phenomena of seasonal or postpartum alopecia, but we can anticipate them. "Without guaranteeing miraculous results, some vitamin B, zinc and sulfur amino acids (cysteine ​​and methionine) cocktails, for example at Physio or Forcapil, will strengthen the root and activate the micro-circulation at the bulb", details Gersende Moysan, hair specialist at the Clauderer Center. You must take these food supplements continuously two to three months upstream and follow the cure to the end.
In everyday life, we adopt a healthy lifestyle: "The colors, strands or straightening house can damage the roots.I advise to return to a natural hair, and basic products: a shampoo anti-fall, it does not exist . " Shampoos are therefore preferred with mild washing agents purchased in drugstore, such as Furterer or Vichy.
When should we worry?
When hair loss, brutal, settles outside the passenger phenomena, it becomes pathological. Alopecia can be a result of a physical change (diet, illness, taking certain medications) as psychological (stress period, depression). More rarely, to a psycho-emotional shock. It is then necessary to consult quickly a dermatologist.
How to react?
A blood test can identify a possible thyroid disorder or deficiency. We then dose iron, zinc, folates (vitamins B9), which the doctor will supplement by prescribing the appropriate nutrients. A trichogram, that is to say a study of the roots under a microscope, also makes it possible to determine the causes of alopecia.
To stimulate the hair follicle and rebalance the vital functions of the hair, we can turn to dermo-cosmetics spray, to penetrate by massaging the scalp. It is found in Ducray (based on tetrapeptides) or Klorane (quinine and caffeine). One imperative, be patient: there will be no results before 4 months of treatment.
Alopecia areata, seborrheic dermatitis ... Pathologies to take into account
Some diseases have the effect of blocking the growth of hair. In the case of alopecia areata, the hair follicle suspends its activity unpredictably, creating patches of baldness on isolated areas of the scalp. Prescribed treatments, such as local corticosteroid therapy, aim to remove white blood cells that attack the follicle.
Characterized by dandruff and pink plaques covered with crusts, seborrheic dermatitis is due to the proliferation of a fungus, malassezia, which colonizes fatty scalps. Treatments can reduce but not cure dermatitis: if a dandruff shampoo is not enough, a treatment lotion, based on antifungal and anti-inflammatory, will be indicated.
The special case of chronic hair loss
Although more frequent (85% of cases), chronic alopecia worries by its inescapable aspect: the hair is gradually becoming scarce, specifically on the top of the head. This plague depends both on hormonal hyperactivity and hereditary predisposition: if your mothers, grandmothers or aunts are affected, there is little chance that you escape.
Minoxidil 2% or 5% (Alopexy for example) has long been proven. But the treatment (for life and not reimbursed) is binding: the lotion is applied twice a day, can leave the hair greasy and
