Menopause and hair loss: what's the connection?

At the time of menopause, a woman experiences a decrease in hormone production. Indeed, the life cycle of hair is highly sensitive to any hormonal variations, which can consequently affect the quality and growth of hair. However, is this link well established? Let's clarify this in this article.

Does menopause promote hair loss?

The menopause is the stage in a woman's life when her menstrual cycles permanently cease, typically occurring around the age of 50. During this time, the body experiences a hormonal imbalance with a decrease in the levels of oestrogen and progesterone which usually protect the hair, and an increase in the levels of androgen, naturally occurring hormones in the human body that are responsible for the development of male characteristics. The primary source of oestrogen after menopause comes from the conversion of adrenal androgen into oestrogen by the enzyme aromatase in peripheral tissues. This hormonal fluctuation is often cited as a cause of hair loss in some women.

Scientific studies assert that oestrogens contribute to hair growth. Indeed, these hormones are believed to prolong the anagen phase although their mechanism of action remains largely unknown. However, with the decrease in oestrogen levels, the anagen phase is no longer extended. Furthermore, the relative increase in androgen levels leads to an acceleration of the hair cycle and the renewal capacity of hair follicles prematurely exhausts. This acceleration of the hair cycle is due to testosterone, an androgen hormone, which secretes dihydrotestosterone (DHT). The latter is known to shorten the anagen phase (growth phase) and increase the telogen phase (shedding phase) although its mode of action is not yet clear. The hair will become thinner and then fall out. It is important to note that the hormonal variations encountered during menopause are unique to each woman, which explains why some of them will not experience this problem of hair loss.

It is estimated that two-thirds of menopausal women experience hair loss. This hair loss observed during menopause can be linked to genetic factors or external factors such as nutritional deficiencies, or stress.

How to limit hair loss during menopause?

It is possible to limit hair loss during menopause through the use of certain hair care treatments (shampoo, ampoules, etc.) that are anti-hair loss, which help to reduce hair fall.

You can also use densifying treatments such as our scalp treatment. It is effective for both chronic and occasional hair loss. The pea peptides (INCI: Pisum Sativum (Pea) Peptide) stimulate the dermal papillae and extend the life cycle of the hair. Ginger extract (INCI: Zingiber Officinale (Ginger) Root Extract) is known for its anti-hair loss properties.

Incorporate biotin and iron into your diet. These compounds promote hair growth and enhance its vitality. Iron can be found in meat, fish, seafood, etc. Biotin, on the other hand, is primarily found in egg yolks, mushrooms, beans or lentils. It is also possible to take them as dietary supplements during menopause.
