Do eyelashes grow back when you cut them?
How long a hair can grow before it falls out is basically genetically determined and also depends on a number of factors. Unfortunately, scalp hair or eyelashes don't get thicker or longer when you cut them.
Unfortunately, it's a wives tale that if you can hair cuts, they grow back faster and thicker. It is only the disposition that ensures the maximum length, color or density of your hair. Only the structure of the individual hair, which is responsible for whether hair grows straight or curly, can change in the course of life.
Even if you cut them, hair does not grow any faster or thicker
- Are you blonde Then you have an advantage - at least as far as the number of hairs on your head is concerned, because blondes have twice as much hair on average as redheads. While blond people have around 150,000 hairs on their heads, only around 75,000 grow in redheads. Brunettes have around 100,000 hairs, while black-haired people only have around 10,000 more hairs on their heads.
- Hair grows about 1/3 millimeter per day. That doesn't sound like a lot, but if you do the math, you get about 1 centimeter per month; that's at least 12 centimeters per year.
- The speed at which hair grows cannot be influenced from the outside. Even if you cut them, this has no effect on the growth and density of the hair.
The life cycle of a hair goes through three phases
Hair grows over several years and goes through three phases:

There are some stories about hair that are passed on from generation to generation ...
- In the first phase, a new hair root is formed and hair production begins. This phase lasts about 2 to 6 years. How long it actually lasts depends on age and gender. In addition, the area of skin where the hair grows has an influence on the phase length.
- In the second phase, which is a two to three week transition phase, hair production is stopped. The hair loosens and eventually falls out.
- In the third phase, the hair follicle prepares for the production of a new hair. This phase lasts around 2 to 4 months.
Thick, long eyelashes - a matter of genetics
- The number of eyelash hairs between the upper and lower eyelids is quite different. While on the upper eyelid margin about 150-250 Eyelashes grow, there are only 50-150 eyelashes on the lower edge of the eyelid. If you now visualize the small area over which the eyelashes are distributed, you can imagine how dense an eyelash line can look from person to person.
- In addition, the length of the upper and lower eyelashes can also vary. While eyelashes are between 8 and 12 millimeters long at the top, they are only 6 to 8 millimeters long at the bottom.
- Unfortunately, eyelashes fall out after 100 to 150 days. So they have a much shorter life cycle than scalp hair.
