A hair loss is mostly unavoidable. All of us at some point in our lives have experienced it. A lot of factors in our lifestyle and health conditions can influence how much our hair falls out. From stress, malnutrition or nutritional deficiencies, to illness and trauma, our hair can start to fall out. That is why today we are going to tell you about some of the most common causes of hair loss. So that you have a better idea of why your hair is falling out.

Causes of Hair Loss

Hair loss has become an everyday occurrence. Actually, it’s quite normal for us to lose a few strands every day. But how do you know when this loss stops being normal and becomes a problem? Let’s look at some of the main causes of hair loss.

Pregnancy and childbirth

It is probably one of the most talked about and least explained causes of hair loss. For some women, when they are pregnant, their hair grows out and becomes abundant and beautiful. It also tends to fall out very little or not at all. This is unfortunately not a permanent problem. Later, during the postpartum period, such beautiful hair starts to fall out excessively. So why does that happen?

During pregnancy, hair remains in the anagen phase, i.e. growing out all the time, due to hormonal changes. This is why it becomes so abundant. When the baby is born and the hormones change once again, the hair goes into the catagen (transition) and telogen (rest) phases. However, as part of the natural process, all that hair that builds up is finally ready to be shed.

What causes a bit of an impression and concern is that this happens as quickly as possible and all at once. However, it’s something you shouldn’t worry about. In a few months the hormones will be back in balance and so will the hair growth.


Experts believe that fighting genetic hair loss from the start is the key to altering what may seem inevitable. Female pattern hair loss can occur in the 20s and 30s, especially if it is a problem that has occurred in other members of your family.

The key to combating hereditary hair loss is to start a routine that focuses on the scalp and overall health. This may include a multitude of treatments, from supplements to the right products and diet.

For this reason, it is important to keep a close eye on your hair loss. If we start to notice more hair falling out than usual, we should visit your dermatologist for an evaluation.

Neglected scalp health

Infrequent shampoo application and accumulation of products from dry shampoo, products that are not rinsed or improperly rinsed can actually block the opening of the hair follicle. Not taking care of our scalp can lead to problems such as dandruff and psoriasis, so frequent washing and rinsing to avoid product build-up is key to taking preventative measures against hair loss.

Underlying disease

Underlying medical problems or diseases, i.e. conditions or disorders that remain hidden or underneath a group of symptoms, can influence any hair loss you are experiencing. Thyroid problems are one of the main diseases responsible for hair loss. Other hormone problems, such as polycystic ovary syndrome, may also be part of hair loss problems, as is the case with any autoimmune disease.

Being aggressive with your hair

Having hairstyles that are in trend or braids can be a great idea for a stunning look. However, if it’s not done delicately it can lead to hair loss. According to experts, too much tension and excessive or constant pulling of the hair can lead to something called traction alopecia.

Hair styles that are extremely tight such as ponytails, braids and even extensions can lead to hair loss. The use of spiral ribbons or silk hair bands can be a softer alternative for holding hair in place without breaking it. It is also useful to make sure you are using the right type of hair brush, especially when combing in heat.

Thermal and chemical treatments

Treating hair such as bleaching and dyeing it too often can cause serious damage. It is advisable to talk to your stylist about the health of your hair so that you can address your colour goals in a responsible and respectful manner.

Using straighteners and tongs can also create problems for your hair, making it more brittle, damaged and prone to breakage. This is why it is advisable to apply heat protection before brushing your hair. Furthermore, get frequent cuts and give your hair a few days’ rest from the heat. This will help prevent hair loss to a great extent.

Vitamin deficiencies

Vitamins and minerals play an important role in maintaining healthy hair. Most common deficiencies related to hair loss are found in vitamin B12, biotin, folic acid and riboflavin. Fortunately, supplements are available to help correct these imbalances. Only for this reason, the case for taking a daily multivitamin has never been better.

Lack of protein

Nutrition also has an impact on the health of our hair. Certain deficiencies in the diet can cause unfavourable results, such as hair loss. Such is the case with a lack of protein. The lack of essential amino acids in diets that do not include animal protein can be a major problem. Therefore, getting an adequate amount of protein in our diet is essential for strong and healthy hair growth.

Rapid weight loss and calorie restrictions can also lead to thinning and hair loss. That is why it is very important to consult a nutritionist who can guide and create a diet. This must be geared to the specific needs of each individual. To avoid excessive calorie restriction.

Hormonal changes

Many hormonal changes are experienced by a woman in her life. The postpartum period, the menopause, between events create a hormonal imbalance and lead to hair loss. If hormonal levels are not balanced, you can experience chronic hair loss. This will not stop until your levels are regulated.


During times of high stress, the body shuts down less important systems in an effort to heal itself. This unfortunately includes the capillary system. That is why any situation that causes a lot of stress will almost always have an effect on the hair.

Prolonged episodes of stress and a stressful lifestyle can eventually cause permanent damage to your follicles. Which is why it is important to seek help to lower high levels of stress. By being more calm and relaxed the hair loss will stop.
