Top 7 Reasons for hair loss

Main reasons for hair loss


They are just follicles and yet a lot of social dynamics and self-image are playing out on our heads. Our hair is very much part of who we are, and hair loss can be distressing for both men and women. However, as we age, it is indeed normal to experience some form of hair loss, and in fact, we lose between 50 and 100 hairs from our heads every day. Losing hair is part of the natural hair cycle, but when hair loss is more than usual or/and happens suddenly, it can be alarming and affect you.

Here we will take a look at the most common causes leading to hair loss.

Some people might be more likely to experience hair loss or not based on their genetic predisposition. If you have a history of balding in either your mother’s or father’s side of your family, then it could be a reason for your hair loss.

One of the most common types of genetically related alopecia (hair loss) is androgenic alopecia. Androgenetic alopecia is a common form of hair loss in both men (male-pattern baldness) and women (female-pattern baldness).

In men, there is a well-defined pattern in losing hair, starting above both temples. Over time, the receding hairline tends to form an “M” shape. Additionally, there could be hair thinning at the crown that could worsen to partial and even complete baldness.

The pattern of hair loss in women differs from the male one as the hair becomes thinner all over the head, and the hairline does not recede. Moreover, Androgenetic alopecia in women rarely leads to total baldness.


Hormones are considered one of the main risk factors for hair loss in both men and women. In fact, the hormones affecting hair loss include dihydrotestosterone (DHT), thyroid, and estrogen hormone. In the case of a disruption to the hormonal cycles, or a sudden change in hormone levels then that could lead to hair loss.

Testosterone is released continuously in men and levels decrease progressively as we age. This decrease in testosterone can lead to hair loss in some men.

And for instance, for some women, hair loss can happen during menopause due to the change in hormone production, and also in pregnancy, when estrogen level rises.

Environmental factors & lifestyle

Another cause of hair loss can be related to environmental factors and the lifestyle one leads. In general, leading a healthy lifestyle, including not smoking, drinking in moderation, avoiding excessive sun exposure, and following a healthy diet, will help to keep your hair strong in addition to feeling better for your overall health.

However, there are external factors that can cause hair loss, of which we have less control over. Some of those triggers include for example:


Some stress to the body can cause hair loss even weeks after an event. This could be physical stress after a surgical trauma but also But, it’s not just physical stress but also psychological, emotional stress such as long periods of stress and angst can be linked to hair loss. In these instances, however, hair loss is often temporary.

That is why it is important to manage and mitigate the source of stress in order to help regrow your hair.


Pollution is also a source of skin damage and premature aging and can also affect the hair. After all, the scalp is an extension of our skin. The fact is that environmental pollution contributes to an increase of free radicals in the body, which in turn triggers a process called oxidative stress. When this happens, your immune system isn’t able to fight and neutralize all the free radicals effectively. These free radicals can then damage the cellular membranes, lipids, proteins, and even DNA, which can be a contributing factor towards losing hair.

Iron, zinc, and vitamin deficiencies can contribute to hair shedding, so it’s important to follow a varied, healthy diet.

Another illness could be polycystic ovary syndrome (PCOS). And finally, Fungal infections of the scalp are also connected to hair loss. Furthermore, hair loss can be associated with some medications.
