Hello dear readers of the site. Most people don’t even think about why they need their eyelashes at all. They don’t think about what they are made of, how they grow, etc. And today we decided to fix it. We will tell you about what they are, what functions they perform and present a number of interesting facts about these hairs bordering the eye section above and below.
Their growth cycle has three stages: anagen, catagen, and telogen. Anagen is the most active stage of growth. It takes approximately 2-3 weeks for the lashes to grow back to full length. Usually their growth rate is 0.5 mm per day. After anagen, the catagen stage begins. This is a transitional stage. This stage also lasts 2-3 weeks. During this stage, the eyelashes stop growing and the follicle closes.
The last stage is telogen. This is the resting stage. The eyelash can stay in this stage for up to 100 days. At this time, it does not grow or change. Most of the eyelashes in front of your eyes are at rest. That is, they no longer grow. This means that if you cut your eyelashes, they will not grow back. You will have to wait about 3 months until they fall out and new ones grow in their place.
Each eyelash goes through a cycle in its assigned time, which means that you will never be left without eyelashes. Most people, on average, lose one to five eyelashes every day. Moreover, if they do not fall out in a person, then this may be a sign of health problems.
Only mammals have them. They serve as a kind of barrier that protects our eyes from dirt, sweat, water and other unwanted debris. Moreover, like a cat’s whiskers, they are sensitive to adaptations and tell us when insects, debris and dirt are trying to get into our eyes.
That being said, it should be noted that there are animal exceptions. In particular, this applies to the ostrich, which is a bird, but at the same time it has quite expressive and lush eyelashes. By the way, they are used to make artificial false eyelashes, excellent artistic brushes, etc.
They begin to grow even before we are born. Scientists claim that they begin to form in the embryo at 7-8 weeks of gestation.
They are composed only of water (only 3 percent) and keratin (97 percent). Keratin is a protein that also makes up hair and nails. Therefore, in order for the eyelashes to remain strong, you need to eat all those foods that strengthen hair and nails, in particular, chicken eggs, almonds, etc.
The rocky glands of Zeiss are located near each cilium. They differ from the sebaceous glands in their small size. The secret secreted by the rocky glands of Zeiss is very much like wax in nature. There are also other glands in the area of the eyelashes – the Moll glands. They are like sweat glands. These glands secrete substances that keep the eyes from drying out and even help prevent bacterial growth.
They have been looked after since ancient times. There are records dating back to 4000 BC, which indicate that the ancient Egyptians used kol for dyeing eyelashes.
As for the first non-toxic mascara, it was invented by the French businessman Eugene Rimmel back in the 19th century.
The very first mascara in the form familiar to us was developed by Tom Williams and was a mixture of petroleum jelly and coal. And the very first modern mascara was invented by Maybelline in 1917, which to this day remains one of the leading cosmetics companies in the industry.
Tiny mites live on the eyelashes. They are small parasites, only about 0.2 mm in size. These parasites are called acne glands. But in fact, they are harmless to humans. While you are awake, asleep, etc., they remove dirt and debris, helping to cleanse the eyelash follicles, thus protecting the eyes from infections. There are about 65 types of acne glands, but only two are found in humans: Demodex folliculorum and Demodex brevis.
You have probably already noticed that they are longer and thicker on the upper eyelid than on the lower. On the upper eyelid, there are usually longer eyelashes, which, moreover, are 2-3 times more than on the lower one. On average, in the upper eyelid, their number varies from 200 to 300 units. The lower eyelid has only about 100 hairs. In the middle part, they are also longer (both below and above) than on the sides.
Can you imagine eyelashes longer than 12 cm? At first glance, it seems that this is simply impossible. But this is not the case. A woman named Yu Jianxia was able to grow them up to 12.40 cm.This way she earned herself a place in the Guinness Book of Records in 2018. She beat the previous record holder Canadian Gillian Criminisi, who was able to grow them to 8.07 cm.
In general, men do not give them as much attention as women do. Men do not look after them, and they do not try to lengthen them. But at the same time, nature has disposed so that they are longer just for men, not women.
If you look at the paintings depicting medieval women, you may notice that they do not have eyebrows and eyelashes. But why were they portrayed as such? Even the famous Mona Lisa does not have eyebrows and eyelashes. The thing is that at that time there was such a fashion. Women tried to make their foreheads bigger, which forced them to shave off their eyebrows and eyelashes. Such were the standards of fashion.
It consists of a root (that part of it, which is under the skin) and a shaft (its visible part). The root is located at a depth of about 2 mm.
If we look at them, it will seem that they grow in one row. In fact, this is not the case. On the upper eyelid, they grow in two to four rows, and on the lower eyelid in 1-2 rows.
Their color may differ from the color of the hair, but most often they are darker in people with dark hair, while in people with light hair they are lighter.
Regular use of medications such as aspirin or ibuprofen can slow the rate of hair growth and hair growth in general.
That’s all for us, dear readers. Thank you for your attention to our website.
