Hair loss does not have one cause but several possible ones, and the right treatment depends entirely on which is at work. In Marrakech, Dr Sara Zahid, a dermatologist in Guéliz, therefore starts by looking for why your hair is falling out: questions, scalp examination, trichoscopy and, if needed, blood tests. It is the only way to tell a temporary shedding, which stops by itself once the cause is removed, from alopecia that is setting in and needs long-term treatment. The earlier you come, the more hair you keep.
Androgenetic alopecia, the most common, gradually thins the crown and temples in men, and the parting and top of the head in women. Telogen effluvium is a diffuse and sudden shedding, triggered two to three months earlier by a shock: childbirth, fever, dieting, stress, deficiency. Alopecia areata forms round patches, sometimes widespread, of autoimmune origin. Other hair loss comes from repeated traction, tight hairstyles or a scalp disease.
You are asked when the loss began, what happened in the preceding three months, your periods, your diet, your medicines and family history. Trichoscopy, a painless examination of the scalp with a magnifying device, shows miniaturisation of the hairs, inflammation or density. Blood tests (iron and ferritin, thyroid, vitamin D in some cases) look for a deficiency or imbalance to correct.
In androgenetic alopecia, treatments slow or stabilise the loss and, in some people, regrow part of the hair: topical minoxidil or, in some cases, oral, and anti-androgen treatments in men or depending on the hormonal context in women. These treatments take several months and long-term use. In effluvium, the cause is treated and regrowth is awaited, which takes three to six months.
Hair PRP consists of injecting platelet-rich plasma, prepared from your own blood, into the scalp. Mesotherapy injects active ingredients. These are supporting options, discussed after assessment according to the cause: they do not suit every situation and do not replace underlying treatment. The expected benefits and limits are explained before any protocol.
Two to four months after giving birth, heavy shedding is common and usually temporary: the hair, plentiful during pregnancy, falls out all at once. A consultation is useful if the loss is heavy or prolonged, to check iron and thyroid. The dermatology and pregnancy page covers this point.
Hair regrows slowly, and a treatment is judged over several months. Photographs of the scalp taken under the same conditions at each consultation make it possible to measure progress objectively and to avoid changing treatment too soon out of impatience.
Depending on what you observe, the page closest to your situation is: hair loss in women (fine hair, wider parting, after childbirth), alopecia areata (round bald patches), baldness or androgenetic alopecia (temples, crown), and scalp mesotherapy as a supporting treatment. Each diagnosis has its treatments; the scalp examination settles it.
As soon as it seems abnormal or lasts more than two to three months, or if bald patches appear. The earlier the cause is identified, the more effective the treatment.
Losing fifty to a hundred hairs a day is normal. What should alert you is a clear change: more hair in the comb or on the pillow, a widening parting, a thinner ponytail.
Yes in the great majority of cases, within a few months. If it persists or is very marked, a deficiency is looked for.
An autoimmune disease that causes bald patches, sometimes with no other sign. It can appear without a visible cause and is treated in several ways depending on its extent.
No. It can be discussed in certain indications after assessment, but its value depends on the cause identified.
No, it is a non-invasive examination, with no preparation.
Often, when the loss is diffuse: iron, ferritin, thyroid and sometimes vitamin D, to look for a deficiency or an associated disease.
Androgenetic alopecia is hereditary and progressive, with hair that gets thinner. Alopecia areata causes round bald patches and is not contagious. Effluvium is a diffuse, sudden, temporary shedding that follows a trigger. The diagnosis is made by examination and trichoscopy.
If it is very marked, lasts more than six months or comes with other signs (tiredness, patches), yes: iron and thyroid are checked. Otherwise it is most often temporary.
