While our hair can grow meters, why can’t our hair like eyebrows and eyelashes grow?

When we cut our hair, it grows back in a reasonable amount of time, but after a while it grows slower and even stops. However, our hair are the longest hairs on our body† Our eyelashes and eyebrows, which are made of bristles like our hair, can never grow as long as our hair. But what is the underlying reason why our hair and other hairs are so different?

come together now, the growth stages of hair in our bodyLet’s look at the phase differences between hairs and how long each hair grows.

The anagen phase determines how and how long our hair will grow.

phases

The growth of our hair is called a hair follicle. by up to 5 million structural members is provided. While all the growth in our hair is taken care of by the follicles, the growth usually takes place in the anagen phase. The more follicles there are in an area and the longer the anagen phase, the more long hair we have.

Every hair has a certain yield point because the anagen phase works differently in each hair.

The longest hair on our body is usually our hair. The reason why our hair has the longest hair is: The anagen phase can last up to 7 years.† Although gender, age, genetic factors and hormonal effects play an important role in determining this period, the length of the anagen phase generally ranges between 2 years and 7 years. In addition, about 100 thousand of the 5 million hair follicles in the human body are located in the hair.

In the anagen phase, our hair grows every month. about 1 cm extends. With short hairs such as eyebrows and eyelashes, this phase lasts only 30 days. The anagen phase is also called the growth phase because of its function. We can clearly say that Anagen lives up to its name in this regard.

Like everything else, hair growth has an end, and this pause period is provided in the catagen phase.

Imagine if our eyebrows or eyelashes could grow as long as our hair. In this case our eyebrows and eyelashes could not fulfill their duties And also, these hairs would cause serious problems for us in our daily life, wouldn’t they?

Eyebrow

The hairs on our bodies, especially our eyebrows and eyelashes, stop growing after a certain time. in the hair the growth has almost stopped This phase, also called the transition phase, where blood flow to the hair and hair stops, is called the catagen phase.

When it’s time to say goodbye to our hair…

Undoubtedly the phase that awaits us after the catagen phase the stage where we say goodbye to our hair is the telogen phase. At this stage, our hair leaves our body. While the most common example for the telogen phase is the strands of hair we touch while showering, we can actually talk about the same scenario for our eyebrows, eyelashes, and all other hairs.

rest phase After the telogen phase, the cycle goes back to the anagen phase and we have hair that grows back. If the hair does not grow back (eg baldness) in the spill area, the kenogenic phase comes into play instead of the anagen phase.

That statement that everyone has heard, but which is completely unfounded: “When we use a razor or shave, our hair becomes harder and thicker”!

To shave

Especially during adolescence, boys often heard this phrase. No research has been done on this topic from past to present, shaving increases hair or it got no result that it got thicker. The success of this method, which is followed for more beard growth during adolescence, is also a purely hormonal situation because beards do form during puberty anyway. In other words, trim your beards with scissors, not a razor; If your hormones are causing your beard to harden, your beard will grow and harden over time.
