How to reduce seasonal hair shedding

During seasonal changes, particularly in autumn, it is normal to notice increased hair shedding. However, there is not always cause for concern, as this is a physiological process linked to the natural cycle of the hair follicles, which is balanced by the growth of new hair.

Experts point out that this shedding phase can last between two and four months, and it is common to experience mild hair shedding during this period. However, if this stage lasts longer than usual, or if you notice reduced volume and density together with weaker hair, it may be a sign that your body needs extra care at this time of year.

The stages of the hair growth cycle

The life cycle of the hair is divided into three stages that occur continuously. In other words, while some hairs are shed, new ones grow to replace them. These are the main phases of the hair renewal process:

• Anagen phase: this is the active growth stage of the hair. It lasts approximately two to seven years and is the phase in which most of the hair is found.
• Catagen phase: this is a short transitional stage during which the hair follicle reduces its activity, causing the connection between the hair and the follicle to gradually weaken.
• Telogen phase: this is the final stage of the hair cycle and generally lasts between one and three months. During this time, the hair gradually detaches from the follicle, making way for new growth.

How to reduce seasonal hair shedding

Although seasonal hair shedding is part of the scalp's natural renewal process, several measures may help minimise shedding during these periods:

• Support healthy hair from within. Maintaining a diet rich in vegetables, protein, vitamins and minerals can help strengthen the hair and promote healthy growth.
• Use a shampoo that stimulates the scalp. Choosing products designed to strengthen the hair fibre and encourage growth may help improve hair density.
• Manage stress levels. Various studies have shown that cortisol can disrupt the natural cycle of hair follicles. Relaxation techniques, regular physical activity and controlled breathing exercises can help relieve daily tension.
• Reduce tension on the hair. Hairstyles such as tight ponytails, braids and buns place constant stress on the roots and may weaken the follicles. Looser hairstyles are generally a better option.
• Brush your hair gently. When using a hairbrush, it is advisable to choose one with soft bristles and handle the hair with care.
• Maintain adequate vitamin D levels. Research has identified a close relationship between vitamin D and hair health. To support healthy levels, regular and safe exposure to sunlight is recommended.

When can seasonal hair shedding indicate another problem?

When hair shedding is seasonal and not associated with an underlying condition, its effects can often be minimised. However, if this phase lasts longer than usual, if the hair falls out faster than it regrows, or if other symptoms appear, it may be a sign of an underlying issue that should be assessed by a specialist.

The specialist will evaluate the case, identify the possible cause and, if necessary, recommend the most appropriate treatment to slow hair shedding and support hair regrowth.
