Hair loss is something many people experience at different stages of life, and it can be worrying when you start noticing more strands on your pillow, in the shower, or on your hairbrush. While some shedding is completely normal, excessive hair fall may feel alarming and can affect confidence and self-image. Understanding the reasons behind hair loss is the first step towards managing it, as there are a variety of potential causes ranging from natural cycles to lifestyle and health factors.

Natural Hair Growth Cycle

Before worrying too much, it is worth remembering that hair naturally sheds as part of its growth cycle. Every strand goes through three main phases: growth, rest, and shedding. On average, it is normal to lose between 50 and 100 hairs per day. This is often unnoticeable until the cycle shifts and more hairs than usual enter the shedding phase. Seasonal changes, stress, or illness can temporarily push more follicles into this resting stage, making hair loss appear more sudden.

Genetic and Hormonal Influences

One of the most common causes of ongoing hair loss is genetics. Male and female pattern baldness, known medically as androgenetic alopecia, is hereditary and influenced by hormones that gradually shrink hair follicles. This leads to thinning over time, particularly at the crown or along the parting. Hormonal changes during pregnancy, postpartum, menopause, or thyroid imbalances can also cause noticeable shedding. These shifts often disrupt the normal hair cycle, but in some cases the hair can regrow once hormone levels stabilise.

Stress and Lifestyle Factors

Emotional or physical stress can trigger a type of temporary hair loss called telogen effluvium. This happens when the body is under strain, and it pushes more hair follicles into the shedding phase. Common triggers include major illness, surgery, weight changes, or high stress levels. Diet also plays a role, as deficiencies in iron, protein, or essential vitamins can weaken hair growth. Smoking, poor sleep, and lack of exercise may not directly cause hair loss, but they can contribute to overall scalp and hair health.

Medical Conditions and Treatments

Certain medical conditions can lead to hair loss. Autoimmune disorders such as alopecia areata cause the immune system to attack hair follicles, leading to patchy loss. Scalp infections, dermatological conditions, and chronic illnesses may also affect growth. In addition, some medications, including those used in chemotherapy, blood pressure treatment, or mental health management, can have side effects that include hair thinning or shedding. If you notice sudden or severe hair loss, it is always best to seek medical advice to rule out underlying conditions.

Hair Care and Styling Habits

Sometimes the way we treat our hair can make shedding worse. Tight hairstyles like ponytails, braids, or extensions can cause tension on the scalp, leading to a condition called traction alopecia. Overuse of heat tools, harsh chemical treatments, or strong dyes can also damage the hair shaft, making it break more easily. Choosing gentler styling methods, avoiding excess heat, and using nourishing products can reduce unnecessary stress on the hair and scalp.

The Role of Ageing

As we get older, hair naturally becomes thinner and grows more slowly. The follicles themselves may shrink, and the scalp produces less oil, which changes the texture and resilience of hair. While this is a natural process, it can be made more noticeable by other factors such as hormonal changes or health conditions. Supporting hair health through a balanced diet, good scalp care, and targeted supplements can help slow down the visible effects of age-related hair loss.

Nutritional Support and Collagen

Nutrition plays an important role in keeping hair strong and healthy. Collagen, a protein found in the skin, hair, and nails, provides structure and strength to the hair follicles. As natural collagen levels decline with age, hair may become weaker and more prone to shedding. Ensuring a diet rich in protein, vitamins, and minerals is important, and many people also choose to support their intake with collagen supplements. While collagen will not reverse genetic hair loss, it can help maintain healthier hair growth and scalp condition.

Conclusion

Hair loss can have many different causes, from genetics and hormones to lifestyle, stress, or health conditions. Some shedding is natural, but if you notice sudden or ongoing changes it may be worth looking at your daily routine, diet, and overall health. With the right care, and sometimes professional support, it is often possible to reduce shedding and encourage stronger, healthier hair over time.
