Why do hair become thinner over time? The most common causes

Many people eventually notice that their hair is no longer as dense or strong as it used to be. When they look in the mirror, the crown of the head appears wider, the braid thinner, or the hair loses volume. This does not necessarily mean there is cause for concern at once, because thinning hair can have many different causes.

Is it normal for hair to become thinner?

Yes, to a certain extent this is completely normal. As you age, the hair growth cycle changes. New hair often grows finer than before and the amount of hair can gradually decrease. How severe this change is varies from person to person.

Genetic predisposition

One of the most common causes is heredity. Some people are naturally very dense with hair, while others have fine hair. Hereditary hair loss can also cause the hair to become thinner over time.

Hormonal changes

Hormones have a major impact on hair growth. During puberty, after pregnancy, or in the menopausal period, the hair structure can change. Diseases of the thyroid gland can also contribute to hair becoming finer or falling out more frequently.

Stress

Severe physical or emotional stress can affect the natural hair cycle. Often, this is not noticed until several weeks or months after a stressful phase. In many cases, the hair grows back normally after some time.

Nutrient deficiency

For healthy hair, the body needs, among other things, iron, zinc, biotin, protein, and various vitamins. An unbalanced diet or certain diseases can cause the body to lack important nutrients.

Frequent styling

Regular bleaching, strong heat from curling irons or curling tongs, and tightly bound hairstyles can permanently damage the hair. This causes it to become thinner or break more easily.

What can help?

A balanced diet, gentle hair care, and a healthy lifestyle can help maintain healthy hair. However, if you experience sudden hair loss or noticeable changes, you should consult a doctor to determine the possible causes.

Conclusion

Thinning hair has many possible causes – from genetics to hormonal changes, to stress or nutrient deficiencies. Knowing the cause often allows you to take targeted action and support your hair in the best possible way.
