Environmental changes
Timperley said: “Cooler, drier air combined with indoor heating draws moisture from both your scalp and strands, making hair more prone to dryness, breakage, and shedding. Hats, scarves, and high collars can also create friction that weakens the hair shaft over time.”
Nutritional factors
The expert said: “Shorter days and heavier comfort foods can mean less vitamin D and fewer nutrient-rich meals.
“Low levels of vitamin D, iron, and zinc are all linked to hair shedding, so maintaining a balanced diet rich in protein, leafy greens, and healthy fats is essential for hair health.”
Stress and lifestyle changes
Timperley said: “Autumn and winter often bring busier schedules, less sunlight, and disrupted routines, all of which can raise cortisol levels. Elevated stress hormones can push hair follicles into the telogen or resting phase, causing temporary thinning known as telogen effluvium.”
