Why Does Hair Loss Increase in Autumn?

It is common to notice an increase in hair loss during autumn, and both men and women often wonder whether they should be concerned. Although this phenomenon can be alarming, in most cases it is a natural and temporary process related to the hair growth cycle. In this article, we explain why it happens and what you can do to take care of your hair during this season.

Seasonal Hair Loss: Why Does It Happen in Autumn?

During summer, hair is more exposed to UV rays, heat, and other environmental factors. In response, the body prolongs the hair growth phase (anagen) as a protective mechanism. However, when autumn arrives, many of these follicles enter the resting phase — known as telogen effluvium — which leads to increased hair shedding.

This phenomenon is completely normal and typically lasts between six and eight weeks. In most cases, the hair that is lost will be replaced by new hair, and there is no cause for concern. However, if you notice that the shedding is excessive or persists for longer than usual, it may be a sign of other hair conditions — such as androgenetic alopecia or nutritional deficiencies — that would require the attention of a specialist.

Should Autumn Hair Loss Be a Cause for Concern?

While it is normal for hair loss to increase at this time of year, it is not always a cause for alarm. This seasonal phase of the hair cycle may be more noticeable in people who already suffer from alopecia or have a more sensitive scalp. If hair loss persists for more than three months, or if you notice areas of visible thinning, it is advisable to consult a specialist.

At our clinic, we carry out a personalised diagnosis using advanced technology such as HairMetrix by Canfield, which allows us to accurately analyse the condition of your hair follicles. This assessment helps us determine whether hair loss is within normal parameters or whether it is due to additional factors that need to be addressed. You can find out more about this process on our hair diagnosis page.

How to Care for Your Hair in Autumn

Although autumn hair loss is a temporary phase, there are steps you can take to minimise its impact:

1. A nutrient-rich diet: A balanced diet including foods rich in vitamins A, B, C, and E, as well as minerals such as zinc and iron, is essential for hair health. Supplements such as biotin can also help strengthen hair.
2. Scalp hydration: During autumn, changes in temperature and dry air can affect the scalp, causing irritation or dryness. Using moisturising products and performing gentle massages can improve blood circulation and keep the scalp healthy. We also recommend using mild shampoos that respect the scalp’s natural pH.
3. Avoiding excessive heat and chemical products: Although the weather becomes cooler in autumn, it is important not to overuse hairdryers or straighteners, as intense heat can weaken hair. It is also advisable to avoid aggressive treatments such as dyes or perms during this time of year.
4. Personalised treatments: If hair loss is a concern, there are effective treatments such as hair PRP, mesotherapy, and exosomes that can help stimulate hair growth. These treatments, along with oral pharmacological treatment, improve hair density and quality, complementing the hair’s natural cycle. Both procedures are available at our clinic under the supervision of Dr. Espinosa Custodio and Dr. Gallardo Madrid, who have extensive experience in treating hair loss.

When Is It Time to See a Specialist?

While seasonal hair loss should not last more than two months, if you experience significant shedding, hair thinning, or visible bald patches, it is essential to see a specialist dermatologist. Early diagnosis can prevent permanent loss and offer solutions such as oral medication, intradermal treatments, or regenerative therapies such as hair PRP. At our clinic, Dr. Espinosa Custodio and Dr. Gallardo Madrid develop a personalised plan based on each patient’s individual needs, always combining the best technology with a close and human approach.

A Comprehensive Approach to Hair Care

Both men and women can benefit from a comprehensive approach to hair health. At our clinic, we combine advanced technologies — such as dermatoscope analysis — with personalised treatments to keep hair in its best condition throughout the year. Treatments such as hair PRP and mesotherapy are not only effective for treating autumn hair loss, but also help revitalise the scalp and improve hair density.

Remember that autumn hair loss is a normal process, but if it concerns you or lasts longer than usual, we are here to help you find the most appropriate solution. For more information about our treatments and services, please visit our hair treatments section.

Frequently Asked Questions

Why do I lose more hair in autumn?

Autumn hair loss is a natural process known as seasonal telogen effluvium. During summer, the body retains more hair to protect itself from the sun, and in autumn those follicles enter their resting phase, leading to increased shedding. This phenomenon is usually temporary and should not be a cause for concern unless the hair loss is excessive or prolonged.

How can I prevent hair loss at this time of year?

While it cannot be stopped entirely, autumn hair loss can be minimised with a vitamin-rich diet (particularly biotin, zinc, and iron), by keeping the scalp well hydrated, and by avoiding excessive heat and chemical products. Treatments such as hair PRP or mesotherapy can also help strengthen hair.

When should I see a specialist about hair loss?

If hair loss lasts more than two to three months, or if you notice visible thinning in certain areas, it is advisable to consult a specialist dermatologist. Early diagnosis can prevent further loss and provide appropriate treatments for each individual case. At our clinic, Dr. Espinosa Custodio and Dr. Gallardo Madrid carry out personalised assessments using advanced technology such as HairMetrix by Canfield.
