7 misconceptions about hair loss
1 - Hair loss and hair aging are linked
FALSE. Hair loss has nothing to do with aging. The proof: androgenetic alopecia, of which baldness is its most common form, can appear at any age, in some cases very young, as young as 20, particularly in male patients.
2 - Hair loss is necessarily hereditary
FALSE. Androgenetic alopecia is hereditary, but this is not the case for all types of hair loss. Acute telogen effluvium, or occasional hair loss, for example, has nothing to do with genetics.
3 - Mothers lose their hair after pregnancy
TRUE. The hormonal fluctuations observed during the postpartum period often result in acute telogen effluvium. An estimated one-third, or even half, of women experience occasional hair loss after a pregnancy*.
4 - Stress makes you lose your hair
TRUE. Relatively intense stress can create a pro-oxidant and pro-inflammatory environment in the hair follicle. This lays the groundwork for diffuse hair loss.
5 - Hair loss is irreversible
FALSE. It all depends on the type of hair loss. Acute telogen effluvium is occasional hair loss, for which the outcome is always positive once the triggering factor has been identified and eliminated. Chronic hair loss can also be corrected. However, hair lost due to androgenetic alopecia will never grow back.
6 - Baldness affects mostly men
TRUE. Androgenetic alopecia is a type of chronic diffuse hair loss characterized by episodes of hair loss eventually leading to a miniaturization of the hair and a reduction in hair density. It affects mostly men at a rate of 70% to 80% versus 29% to 42% of women over their lifetime**.
7 - Do anti-hair loss foods exist?
FALSE. Strictly speaking, there is no such thing as anti-hair loss foods. That being said, a balanced diet rich in sulfur amino acids (cysteine and methionine), vitamins B, C and E, zinc, and iron seems to benefit hair growth.
