HAIR LOSS

Thin hair

Losing hair or feeling like you're getting thin-haired can be both frustrating and worrisome. It is common for hair quality to change with age, but stress, diet, genetics and disease can also play a decisive role. Many people find that the hair becomes thinner, more lifeless and that the scalp becomes visible. It may feel like a lost battle, but there is help to be had.

What counts as thin hair?

The difference between thin hair and thinness

Having thin hair means that the hairs are either few in number per square centimeter, or that the individual hairs are finer than normal. So you can have a lot of hair that is thin, or few strands that are thick — but in both cases the hair is perceived as thin. Thin hair is not the same as being thin-haired, but it can be a precursor to thin-hairiness.

If you start to get thin-haired

If you start lose hair and become thin-haired, the changes can come stealthily and look different from person to person. In some, it starts in the temples, while others notice that the hairline gradually creeps backward or that the whorl in the head becomes increasingly prominent. It can also mean that the hair feels thinner overall, loses volume or becomes more difficult to style as before.

Common symptoms of thin hair

Thinning hair is something that often happens gradually and can therefore be difficult to detect at the beginning. Many people notice the change only when the symptoms affect everyday life or daily hair care routine.

Common signs include:

  • Visible scalp, especially in direct light
  • Hair feels flat, lifeless and difficult to style
  • Reduced hair volume
  • Increased amount of hair in the brush or shower drain
  • Thinner braid than before

Why do some people develop thinner hair?

How to get thinner hair? Thin hair is very common and affects both men and women, but in different ways. In fact, up to 70% of all men experience some form of hair loss in their lifetime, while about 40% of all women notice thinning hair after the age of 40. There are many factors that can lead to thinning hair. Some of the most common are:

  • Genetics: Heredity is the most common cause of reduced hair growth in both men and women.
  • Age: Hormonal changes affect the growth and structure of hair.
  • Stress: Both physical and mental stress can trigger hair loss.
  • Dietary deficiency: Lack of iron, vitamin D or protein can make hair weak and thin.
  • Hormonal changes: For example, after pregnancy or with PCOS.
  • Diseases: Thyroid problems, autoimmune diseases or infections.
  • Medications: Some medicines can have a negative impact on how hair grows.
  • Improper hair care: Excessive styling, chemicals and bleaching, heating tools or tight hairstyles can cause hair to break and feel thinner.
  • Scalp Problems: Dandruff, dry scalp or product residues can clog hair follicles and impair hair growth.
Hair that falls off

Thin-haired or hair that falls off? That's how you know the difference

It is easy to confuse thin hair with hair that breaks off, but there are clear differences. Thin hair means that the hairs are thin from root to tip, which often makes the scalp more visible and the hair feels nicer.Hair that goes off, on the other hand, often looks uneven, especially at the tips. There may be short “baby hairs” in the wrong places and the hair is perceived as frizzy and worn. Often this is due to chemical or mechanical damage, such as excessive styling or the use of heating tools.
