Hair loss - the real causes

If you run your fingers through your hair, having a whole lock of hair in your hand, you are not alone. Most likely, what is happening to you is telogen effluvium (hair loss) and everyone has been through periods of severe hair loss. Many factors can trigger this condition. These include weight loss, changes in diet, general illness, fever, surgery, hormonal changes (including pregnancy, childbirth, breastfeeding) and last but not least, psycho-emotional stress. Deficiencies in B vitamins, vitamin D and iron can also lead to hair loss.

What phases does the hair go through?

To explain the cause of telogen effluvium, it is necessary to understand what phases the hair goes through - anagen, catagen and telogen. The first phase of growth involves about 90% of the scalp follicles, the second phase of rest involves about 5% of them and 5% are in the phase of shedding. This balance can be disturbed in some of the above mentioned conditions and then the percentage of hair in the telogen can increase to 50%, whereby they fall out.

What research should be conducted?

Telogen effluvium begins "quietly" and its onset goes unnoticed. Symptoms on the scalp are not observed - no redness, itching or dandruff. Density loss usually starts 2-3 months after the stress trigger and is sometimes combined with nail changes. It is necessary to examine a number of blood indicators to point to a possible cause. Hormones (FSH, LH, estradiol, progesterone, cortisol, testosterone, TSH, T3, T4, androstenedione), vitamins (D, A, E, B9, B12, B6) are examined. The values ​​of micro and macro elements (Fe, Ca, K, Mg, Zn, Se) are checked. The analysis of the results is very complex and is often interpreted in collaboration with a specialist endocrinologist.

The examination by a dermatologist starts with the so-called "pull test" or gentle traction of a lock of hair, after which the lost hair is counted. The next step is trichoscopy or light microscopy. A biopsy is rarely required.


If the cause of hair loss is an underlying disease, the first step is therapy for it. Treatment of effluvium includes local and systemic agents. With a good therapeutic response are used:

  • Minoxidil - is in the form of a lotion or shampoo. For maximum effect, the product is used once a day, and at least 6 months of patience are needed to effectively stop hair loss and grow new hair. As a side effect have been reported inflammation of the scalp, the appearance of hair in unwanted places.

  • Aminexil - an ingredient that is found in many ampoules and lotions for hair loss. Increases blood flow to the hair follicle and stimulates hair growth.

  • Mesotherapy - is an injection of hyaluronic acid, amino acids and growth factors in the area around the follicle.

  • PRP - injection of platelet-rich plasma. A study showsthat platelet granules contain growth factors that strengthen and stimulate hair.
