Hair Loss in Autumn: Causes, Factors and Solutions

Does hair fall out more in autumn?

With the arrival of autumn and the drop in temperatures, many people notice an increase in hair loss. Although this phenomenon can cause concern, it is essential to understand that it is part of the natural hair cycle, where what appears to be hair loss is, in fact, a phase of renewal.

Symptoms and possible causes

Hair loss is most noticeable when loose hairs appear on your pillow, in the shower, or when you comb your hair. You may also notice thinner, weaker hair that looks less healthy.

Although the symptoms are obvious, the causes are not. Hair follows a natural life cycle in three phases: anagen (growth), catagen (rest), and telogen (falling). However, why does hair loss seem to be accentuated in autumn?

Some experts attribute this to reminiscences of the seasonal shedding that occurs in other mammals. Others suggest that it could be due to the effects of summer (sun exposure, chemicals) or the stress of returning to routine, factors that can influence hair health.

Phases of the hair cycle

To understand why hair falls out more in autumn, it is essential to know the stages of the hair cycle:

1. Growth or anagen phase : Root cells are active and hair grows approximately one centimeter per month. This phase lasts between 2 and 6 years.
2. Resting or catagen phase : Lasts between 2 and 3 weeks. During this time, growth stops and the follicle changes shape.
3. Falling phase or telogen phase : After the transformation of the follicle, the hair falls out. This stage lasts between 2 and 4 months, after which the hair cycle starts again.

It is estimated that between 12% and 15% of hair is always in the renewal phase. Therefore, hair loss in autumn coincides with the end of the telogen phase, which began in spring.

Factors that influence hair loss

In addition to the hair cycle, there are other factors that can accentuate hair loss:

• Stress : Continued stress produces free radicals, molecules that oxidize and age the skin, weakening tissues and slowing hair growth.
• Hormonal changes : Hormonal changes, such as those that occur during pregnancy, menopause or thyroid problems, can cause temporary hair loss.
• Climate : Climatic factors such as cold, wind and pollution can damage hair and weaken its development. In addition, the use of heating can also cause hair to become more porous.
• Genetics : The most common cause of hair loss is genetics. In men, it usually manifests as a receding hairline, while in women, thinning hair is seen at the crown area.

Most vulnerable hair areas

Not all hair falls out evenly. The length of the hair cycle varies depending on the area of the scalp:

• Top of head : 3-4 year cycle.
• Time zones : 5-year cycle.
• Occipital region : 7-year cycle.

For this reason, hair in the front area, the temples and the crown tend to fall out more quickly than hair at the nape of the neck.

Hair loss treatments

Although autumn hair loss is part of the natural cycle, there are treatments to address temporary loss caused by other factors:

• Temporary illnesses or conditions : Treatment should focus on the underlying pathology.
• Medications : If hair loss is a side effect, talk to your doctor about alternatives.
• Hereditary baldness : There are pharmacological treatments that can help stop hair loss and stimulate growth.
• Low-level laser therapy : An approved method for improving hair density, although not yet widely used.

Tips to strengthen hair

In addition to treatments, adopting certain habits can help maintain healthy hair:

• Follow a balanced and nutrient-rich diet.
• Use dietary supplements if there is a nutritional deficiency.
• Avoid night work, which can interfere with follicle regeneration.
• Avoid helmets or hats that keep your hair at a high temperature.
• Reduce stress and practice relaxation.
• Stimulate the scalp to improve circulation.
• Protect hair from sunlight and harsh weather conditions.

When to see a doctor

If hair loss is excessive or unusual, it is advisable to consult a health professional, especially if:

• An atypical pattern of decline is observed.
• The hair loss is rapid or occurs at an early age.
• It is accompanied by pain or itching.
• There is patchy baldness on the beard or eyebrows.
• Male pattern baldness occurs in women.

Before the consultation, it is helpful to gather information about personal or family history, the time of onset and pace of loss, as well as any ongoing treatments.
