Hair loss is a problem that affects more and more women and men around the world, and can have a considerable impact on self-confidence. Here are the main reasons why your hair can become brittle and fall out:

• Genetics : Androgenetic alopecia is the main cause, affecting both men and women. It results from the reaction of hair follicles to hormones.
• Hormonal changes: Pregnancy, menopause or stress-related hormonal imbalances disrupt the hair cycle, leading to sudden or prolonged hair loss.
• Stress and anxiety: Physical or emotional stress can cause telogen effluvium, abnormal hair loss due to shock or prolonged stress.
• Nutritional deficiencies: A lack of essential nutrients, such as iron, vitamin D or zinc, can weaken follicles and slow hair regrowth.
• Environment and hair care products: Pollution, chemicals and tight hairstyles can damage roots and accelerate hair loss.
• Natural aging: With age, the production of collagen and keratin decreases, leading to thinning of the hair, but solutions exist to slow down this process.
