Symptoms, causes of hair loss and its difference with alopecia

For many patients, hair loss can be distressing, but fortunately not in all cases it is a harbinger of baldness or disease. According to research by Mega Interesting, we lose between 50 and 150 hairs a day. This figure may increase in autumn.

Why is our hair falling out?

Hair loss can be the result of hereditary factors, hormonal changes, a disease, or caused by medications. Anyone can suffer from hair loss, however, it is more common in men.

Baldness refers to excessive hair loss on the scalp, the most frequent cause is the hereditary factor along with age. Some people try to start treatment to prevent further hair loss and restore hair growth.

Hair loss occurs when the cycle of hair growth and loss is disrupted or when the hair follicle is destroyed and replaced with scar tissue.

Other factors of hair loss are:

Radiation therapy to the head: it is likely that afterward, the hair will not grow back as before.

A stressful event: Some people have noticed a reduction in hair thickness months after experiencing a physical or emotional shock. Fortunately, this type of hair loss is temporary.

Hair Styles and Treatments: Some hairstyles can cause hair loss called traction alopecia. Hot or permanent oil treatments can inflame follicles and cause hair loss.

What is alopecia?

The term alopecia refers to abnormal hair loss. It can affect the scalp or other areas of the skin where there is hair such as eyelashes, eyebrows, armpits, genital region, and beard.

Alopecia is classified into different groups, according to its origin and manifestations, with androgenic alopecia being the most frequent (also known as common baldness), which is responsible for most of the cases, affecting mainly men.

Some other common forms of alopecia are:

Alopecia areata: hair loss not definitive. It is commonly limited to a certain area.

Alopecia Universalis: an extensive form of alopecia areata.

Scarring alopecia: It is caused by the destruction of the hair follicle and is therefore irreversible.

Differences between seasonal hair loss and alopecia

Alopecia is an autoimmune disease, which causes the body to reject the hair follicle and destroy it by perceiving it as a foreign body that must be attacked. As we have mentioned, its main characteristic is that it causes both general and local hair loss. It usually occurs due to endocrine, genetic, infectious, psychological, and eye problems.

Hair loss, in many cases, has a cure. It can appear in many ways, gradually and affect only the scalp or the entire body, or appear suddenly. Some types of hair loss are temporary and others are permanent, giving rise to terms of alopecia.

Symptoms of hair loss

Circular or patchy bald spots: In some people, mild bald spots occur, a small size. It usually affects only the scalp, however, sometimes it also occurs in the eyebrows or beard.

Hair loss on the body: this may be due to some medical conditions and treatments such as cancer chemotherapy. Hair usually grows back.

Patches: These patches spread on the scalp. It is a sign of ringworm. Usually, it’s accompanied by broken hair, redness, inflammation, and, occasionally, secretions.

Loss of hair thickness on the top of the head: This is the most common symptom of hair loss, it can affect men and women as they age. In men, the hairline recedes from the forehead, making a shape similar to the letter M. In the case of women, they present a widening in the separation of the hair.


In most cases, baldness is caused by genetic factors, which means that there really is no way to prevent it. However, you can follow some tips that will help you avoid some types of hair loss.

Avoid tight hairstyles, protect your hair from sunlight and other sources of ultraviolet light, do not smoke, treat it gently when washing and brushing it, and avoid rubbing or twisting it.

These are some measures that can help you prevent hair loss. Before undergoing any treatment, remember to consult your doctor.
