Eyelashes are much more than an aesthetic detail – they serve an important protective function for our eyes. Acting like a natural barrier, they shield the delicate conjunctiva from dust, dirt and other foreign particles – similar to eyebrows, which also prevent sweat or water from getting into the eyes. When a tiny particle or even an insect lands on the fine hairs, it triggers an automatic blink – a lightning-fast reaction that protects the eye.
Their role goes further. They protect the eye from intense sunlight and help ensure it does not dry out. They redirect airflow so that less moisture is lost. These varied functions make eyelashes an indispensable part of our natural protection system.
Eyelashes grow at their own pace and go through several phases before they eventually fall out and regrow. Unlike other body hair, they grow more slowly and renew themselves on a cycle of around five to six months.
There are four main phases. First, in the anagen phase a new hair is produced in the hair follicle and grows actively. After about 90 days it reaches the catagen phase, during which growth stops and the follicle gradually regresses. Around 21 days later the telogen phase follows, where the eyelash is fully developed and remains in the follicle for approximately 100 days. Finally the exogen phase occurs, during which it is shed and falls out while a new one is already forming in the follicle.
If an eyelash is pulled out in the early growth phases, it does not immediately regrow, because the follicle must first run through the whole cycle again. It can therefore take several months before it is fully replaced. This cycle also matters for eyelash extensions: if an eyelash is already in its terminal phase, it may fall out shortly after an extension has been applied.
Long, thick eyelashes are not only a beauty ideal but also a sign of optimal care. For the fine hairs to grow healthily, remain strong and not fall out prematurely, the body needs a balanced mix of vitamins, minerals and healthy fats.
Omega fatty acids are essential for eyelash care because they strengthen hair follicles and promote growth. At the same time they supply the eyelashes with important nutrients. Equally important is iron, which supports red blood cell formation and provides sufficient oxygen to the hair roots. A deficiency can weaken them and even lead to hair loss.
Calcium plays an important role in growth because it strengthens the hair root and improves the structure of the eyelashes. The B vitamins, especially B3, B5 and B6, are also important as they stimulate the metabolism of the hair roots, regulate the sebaceous glands and prevent the eyelashes from drying out. Biotin, also called vitamin H, is considered a true beauty vitamin because it promotes cell growth and helps produce strong, resilient eyelashes.
Vitamin C is not only important for the immune system but also for healthy eyelashes. It protects the hair follicles from damage, supports collagen formation and keeps them moist and supple. Vitamin E acts as a powerful antioxidant, protects hair cells and improves nutrient supply to the eyelashes through better blood circulation.
Apart from vitamins and minerals, proteins are crucial because eyelashes are made primarily of the fibrous protein keratin, which gives them structure and resilience. A protein-rich diet with complete proteins that provide all essential amino acids optimally supports eyelash growth.
Eyelash loss can have many causes, from mechanical stress to nutrient deficiencies and hormonal changes. In most cases the loss of individual eyelashes is a natural process, but if they fall out or break more frequently the cause is often deeper.
One of the most common reasons for stressed eyelashes is mechanical strain. Frequent rubbing of the eyes, improper cleansing with abrasive pads or continuously wearing false eyelashes can weaken the delicate hairs. Certain mascara ingredients can also interfere with the cellular metabolism of the follicles and inhibit growth. In addition, eyelashes need sufficient moisture – without nourishing oils or serums they can dry out, become brittle and break more easily.
But it is not only external factors that matter. Our body also has a major influence on growth. Vitamin and iron deficiencies weaken the follicles, hormonal fluctuations, for example during pregnancy, after childbirth or in menopause, can alter the eyelash growth cycle. Diseases such as thyroid disorders, diabetes or skin conditions can also disrupt hair growth and lead to eyelash loss.
Another underestimated factor is stress. Increased production of stress hormones can shorten the natural growth cycle so that eyelashes fall out prematurely. Some medications, especially during chemotherapy or with long-term use of certain agents, can also cause hair and eyelash loss.
Natural oils are a tried-and-tested remedy to care for eyelashes, promote their growth and protect them from drying out or breaking. Many nourishing oils come from natural cosmetic lines and are free from synthetic additives, making them particularly gentle on the delicate eye area. Each oil has specific properties that can positively affect their structure.
Castor oil is regarded as one of the most effective oils for strong, long eyelashes. It is rich in ricinoleic acid, which stimulates blood flow to the hair roots and thus promotes growth. It also has moisturizing properties and can help reduce hair breakage.
Neem oil is particularly rich in antioxidants and vitamin E, which strengthen the eyelashes and protect them from external influences. It helps regenerate stressed eyelashes and restore their resilience.
Coconut oil scores with lauric and fatty acids that not only promote growth but also provide moisture and make the hairs more supple and resilient. In addition, it has antibacterial properties and protects them from environmental damage.
Carrot seed oil is a real nutrient bomb, containing vitamins A, B and E as well as minerals such as zinc and copper. This combination can stimulate eyelash growth and contribute to their overall health.
Essential frankincense oil has a special property: it contains thymol, a compound that kills bacteria and germs. In this way it protects the delicate eye area from infections and can help keep the eyelash roots healthy.
Eyelash curlers are a popular tool to create the perfect curl and make the eyes appear larger. If used incorrectly, however, they can damage the fine hairs.
In principle an eyelash curler is not harmful when used correctly. It is important to use it only on clean, makeup-free lashes because mascara hardens them and makes them more likely to break when bent. The beauty tool should always be equipped with a rubber pad to cushion the pressure and avoid unnecessary strain on the lashes.
Excessive pressure or too frequent bending can, however, cause them to break, fall out or lose elasticity in the long term. It is particularly problematic if the curler is not kept clean or the rubber pads are worn – the lashes can then be pinched or even pulled out.
Proper eyelash care not only contributes to a beautiful look but also strengthens the hairs and prevents brittleness. Through gentle cleansing, nourishing oils and avoiding harsh products, eyelashes can remain healthy and strong in the long term. Those who consistently use a gentle care routine can look forward to softer, more resilient lashes.
