Hair loss: what to do?

Dec 27, 2023

Hair occupies a significant position in a woman's life, usually symbolizing femininity and glamour. However, it can happen that this much-desired hair abundance does not always live up to expectations in terms of volume and density. Why do we sometimes tend to lose our hair? And above all, what solutions exist to remedy this phenomenon?

What causes hair loss?

Normally, it is common to lose between 50 and 100 hairs per day. Thus, hair loss is often considered abnormal when the daily number exceeds 100 hairs, or when certain areas of the scalp lose more hair than the rest of the skull.

It is possible to categorize hair loss into two main distinct categories: diffuse hair loss (i.e. over the entire scalp), temporary and lasting.

Temporary hair loss

Diffuse transient hair loss, also known medically as “telogen effluvium,” is commonly seen in women. This phenomenon generally extends over a period of three to four months . The triggering factors are varied and include:

  • Hormonal imbalances such as stopping the pill and polycystic ovary syndrome.
  • Major psychological shocks.
  • Childbirth. Hair loss then occurs about a month after birth (or even more in breastfeeding women). It is usually caused by iron deficiency during pregnancy.
  • Miscarriage, abortion.
  • Physical stress such as prolonged anesthesia, rapid weight loss, or high fever.
  • Certain hair practices such as coloring, straightening or tight hairstyles (ponytails, curlers, etc.).
  • Trichotillomania, a behavior consisting of regularly pulling out a few hairs.
  • Infectious causes such as ringworm or autoimmune diseases such as alopecia areata, leading to localized hair loss.

Although frequently anxiety-provoking, this phenomenon of diffuse hair loss is transient, followed by complete regrowth , not having a permanent impact on hair health. Once the underlying cause is treated, the hair follicles return to their normal growth cycle.

Long-term hair loss

Long-term diffuse hair loss unfortunately does not guarantee complete regrowth . Here are the main causes:

- Side effects of certain medications, chemotherapy being probably the best known.

- Psychological causes such as excessive stress or severe depression.

- Eating disorders such as zinc, magnesium or calcium deficiencies, or conversely an excess of vitamin A.

- Thyroid problems.

- Diabetes.

- Burns or radiation, particularly following radiotherapy.


Also called "androgenetic alopecia", this condition manifests itself in men by thinning and depigmentation of the hair, which can progress uniformly towards general thinning or more specifically affect an area. In women, baldness is also possible . It presents in a more diffuse manner, affecting the entire top of the skull while sometimes preserving the frontal margin. It can occur at any age, with increased frequency after menopause.

Prevalent among men of European origin, it affects between 20% and 40% of them at different stages of their lives. Although less common in women, it represents 80% of cases of lasting hair loss in this population. Causes of this condition include genetic predisposition, the influence of androgens, particularly testosterone-derived DHT, as well as hormonal factors such as the use of oral contraceptives and menopause treatments. Stress and excess cholesterol are also risk factors in women.

How to prevent or limit hair loss?

Therapeutic approaches to hair loss are determined based on the identification of its cause, requiring in-depth analysis to implement measures adapted to each situation. It is often recommended to consult a dermatologist to obtain an accurate diagnosis and initiate treatment. For example, in the case of alopecia areata, corticosteroid therapy may be implemented. At the same time, preventive or mitigating measures can be considered.

The role of diet

Food is the first area on which it is possible to have an impact. It is recommended to adopt a balanced diet , rich in fish, green vegetables and fruits. This type of diet provides essential nutrients such as vitamins, minerals and proteins, which promotes hair growth and prevents hair loss.

It is crucial to ensure adequate intake of protein and iron , essential for the formation of keratin, the protein that makes up hair and nails. For hair growth and root oxygenation, foods such as red meat, poultry, fish and seafood are therefore recommended. Sometimes iron supplements may be prescribed, particularly in cases of telogen effluvium.

Monitoring zinc intake is also important. Zinc is mainly contained in foods such as oysters, seafood, red meat, seeds and fish. Egg yolk and lentils, rich in sulfur amino acids, iron, zinc and B vitamins, are beneficial for hair health.

Focusing on essential fatty acids , such as omega-3 and omega-6 contained in rapeseed, walnut or soy oils, is also recommended to maintain good scalp health. Finally, in case of excess vitamin A, reducing its consumption can help reduce hair loss.

The importance of a good hair routine

Taking care of your hair every day can also help reduce hair loss.
Firstly, it is best to wash your hair with mild shampoos , at a frequency not exceeding twice a week (frequent washing tends to lead to hair loss), using a minimum quantity of product. You should also avoid baby shampoos, which can leave hair greasy.

Permanents, aggressive coloring and straightening should also be avoided . Brushing should be done with a soft brush, avoiding pulling on the roots (it is recommended to squeeze them in the hand to prevent excessive traction on the hair base). It is essential that brushing is not aggressive . Hairstyles that put pressure on the hair follicle, such as buns or braids, should also be avoided.

It can also be beneficial to integrate taking plant-based food supplements into your routine. Some are in fact specially designed to strengthen hair health by reducing hair fragility while stimulating hair growth.

Stress management

Since excessive stress can contribute to hair loss, adopting stress management techniques can be beneficial. Methods such as meditation, yoga, regular physical activity , or relaxation can help reduce stress levels and, therefore, reduce hair loss.

Natural herbal treatments can also significantly reduce anxiety and stress.

In short, hair loss, whether temporary or lasting, requires a comprehensive approach. From dermatological consultation to stress management, including a balanced diet and a suitable hair routine, every aspect must be considered. To reinforce these measures, the integration of food supplements can also be considered. By understanding the causes and adopting appropriate lifestyle habits, it is generally possible to alleviate hair loss and promote hair growth, thus preserving the beauty and vitality of the hair.
