Seasonal hair loss — Why Hair Shedding Increases in Autumn and Winter
Seasonal hair loss is a common and natural phenomenon. As the seasons change, hormonal shifts occur in the body that can temporarily affect the hair growth cycle.
While the exact cause is not fully understood, experts believe that shorter days and reduced sunlight exposure play a key role. Many people notice increased hair shedding in early autumn, with hair loss often becoming more noticeable during the winter months.
The Hair Growth Cycle Explained
Hair grows in a continuous cycle made up of different phases:
-
- Anagen phase – the active growth phase
- Telogen phase – the resting and shedding phase
Seasonal changes can disrupt this cycle.
The Telogen Phase and Seasonal Shedding
With reduced daylight, some hair follicles are signalled to move prematurely from the growth phase into the resting (telogen) phase.
During this phase:
-
- Hair sits more loosely in the scalp
- Hair sheds more easily when washing, brushing, or styling
- New hairs pushing through can cause resting hairs to fall out
This process explains why hair shedding can suddenly feel more intense during autumn and winter.
Seasonal Changes Affect Hormones Too
A similar hormone–sunlight relationship occurs in spring, when increased daylight encourages hair to re-enter the growth phase. This natural cycle helps explain why seasonal hair loss is often temporary.
As long as hair regrows normally, seasonal shedding is not usually a concern. However, hair growth disorders are becoming more common, and in some cases hair may:
-
- Grow back thinner or finer
- Regrow unevenly or diffusely
- Appear weaker or slower to return
This is where targeted support becomes important.
How can Thymuskin help?
Thymuskin is designed to support the hair precisely where growth begins — at the hair root.
Innovative GKL-02 Thymic Peptide Complex
Thymuskin contains the patented GKL-02 Thymic Peptide Complex, an advanced active ingredient developed to support healthy hair growth.
The biological activity of Thymuskin focuses on:
-
- Activating hair cells (keratinocytes), which play a key role in hair formation
- Stimulating the hair matrix to support new hair production
- Encouraging a healthier, longer growth phase
By supporting the natural hair cycle and follicle activity, Thymuskin helps improve regrowth quality during times of increased shedding, including seasonal hair loss.
Supporting Hair Through Seasonal Change
Seasonal hair loss is a natural process, but when regrowth becomes weak or irregular, early support matters. With consistent use, Thymuskin helps maintain scalp health, strengthen hair roots, and support visible regrowth — even during challenging seasonal transitions.
