Causes for eyelash loss
There are many different causes why eyelashes are falling out and they can vary from one individual to another. These causes are ranging from conditions and diseases, some treatments, diets and general care which is given to their eyelashes. Here are the most common causes for eyelash loss:

This is a very short, brittle, fine and thin hair which is seen on some parts of our bodies which we think that they are hairless such as nose, cheeks, brows and lashes. This condition can be inherited or it can be caused by other medical conditions. 
- Menopause: It is normal to experience hair loss or eyelash loss during menopause because there are dwindling levels of estrogen. When you have reduced estrogen levels, then this often slows the growth of your hair and also it can cause hair follicle destruction. Also you will have thinner and fewer hairs and lashes. 
- Dermatological or eyelid skin problems: Some skin infections such as seborrheic dermatitis, psoriasis and eczema can result in itchy sensation which is making people to rub their eyes. This leads to eyelash loss.
- Normal loss: If you have noticed that you have lost a few of your eyelashes, then you should not be worried about it because it is a normal process. They are falling because they are aging so this means that will grow new hairs on those places.
- Some medications: There are some medications which can cause eyelash, eyebrow and hair loss. Blood pressure medications, thyroid balancing drugs, anti – cholesterol drugs, some anti – clotting medications and some oral anti – acne drugs are all connected to eyelash loss. But it is said that when you stop using these medications, then at this moment will start to grow your hair again.
