Unlike other hair in the human body, Eyebrows and eyelashes are prominent and are not diminished over time. They are eye accessories which give a good appearance to our eyes. The question here is what the function of eyebrows and eyelashes is, and why we have this type of hair above and around the eyes?
Eyebrows were found to remove moisture from eyes and play a role in identifying individuals. The area around the eyes is curved and the presence of eyebrows as a fine hair around the eyes is believed to move away unwanted moisture such as rain and sweat from eyes for a clear vision. Eyebrows are directed in a way to facilitate the movement of the moisture to sides around the eyes and sides of the head. They are also involved in filtering dust avoiding its fall inside the eyes and protect against light. There are some diseases due to hormonal disturbances or autoimmunity that may cause hair loss in the eyebrows. These diseases are lupus and hypothyroidism.
Apart from biological functions of the eyebrows, they are an integral part of communications and facial expressions. Individuals can use their eyebrows to express their happiness, anger and surprise. Some researchers found that they can be a potent indicator to recognize identity even more than the eyes themselves.
Eyelashes are hairs that surround eyes and grow in the edge of the eyelids. They have an important function of protecting eyes from dust and debris that may cause irritation and disrupt the field of vision. They are also sensitive to anything that come near to the eyes such as insects and stimulate the auto-reflex of blinking to guard the eyes and keep them well hydrated as well. Eyelashes are a unique type of body hair and keeping them healthy is crucial for a healthy eye and clear vision. The role of eyelashes to avoid eye dryness is significant. They decrease the evaporation of tears from inside the eyes keeping them well lubricated. Having a problem with this can cause eye dryness, irritation, infection and injuries. There are some diseases associated with eyelashes such as trichiasis, blepharitis and styes.
It is now clear how keeping healthy eyebrows and eyelashes is important for your eyes. So, it is recommended to avoid cosmetic hair removal which may cause a loss of their hair. It becomes common now to tint eyebrows and eyelashes which are not advisable as it may be risky. Sometimes, a glaucoma drug called Bimatoprost can be used to increase the length and thickness of eyelashes which can lead to unwanted side effects.
If you want to improve the health of your eyebrows and make them grow thicker in a natural way, you can apply castor oil using a cotton bud. Then use your fingers to massage your brows to improve blood flow and enhance their growth. You can leave the oil over your eyebrows overnight and wash it gently in the morning.
