Losing some hair every day is normal. Most people shed around 50–100 hairs daily as part of the natural hair growth cycle. Problems begin when hair falls out faster than it can grow back, leading to noticeable thinning or bald patches.
Hair loss, also called alopecia, can affect both men and women and may develop gradually or suddenly.
Common Causes of Hair Loss
Genetics and Hormones
The most common cause is hereditary hair loss, known as androgenic alopecia. Men often develop a receding hairline or thinning at the crown, while women usually notice overall thinning and a wider hair part.
Hormonal changes from pregnancy, menopause, thyroid disorders, or conditions like PCOS can also trigger hair shedding.
Stress and Illness
Physical or emotional stress may cause temporary hair loss. Surgery, illness, rapid weight loss, or difficult emotional experiences can push more hairs into the shedding phase. This often appears a few months after the stressful event.
Vitamin Deficiencies
Low levels of iron, protein, vitamin D, and certain B vitamins may weaken hair growth. Vitamin D is especially important because it helps support hair follicles. Deficiency may also cause fatigue, muscle weakness, and low mood.
Other Possible Reasons
Hair loss can also result from:
• Autoimmune conditions such as alopecia areata
• Certain medications, including chemotherapy
• Scalp infections
• Tight hairstyles that pull on the hair
• Frequent bleaching or heat styling
When Should You See a Doctor?
You should seek medical advice if you notice:
• Sudden or excessive hair shedding
• Bald patches
• Itching or pain on the scalp
• Hair loss together with fatigue or hormonal symptoms
Doctors may recommend blood tests to check iron levels, thyroid function, or vitamin deficiencies.
Can Hair Loss Be Treated?
Treatment depends on the cause. Correcting nutritional deficiencies or hormonal imbalances may help reduce shedding. Other options include topical treatments, PRP therapy, and hair transplantation in selected cases.
To support healthy hair growth:
• Eat a balanced diet
• Avoid tight hairstyles and excessive heat
• Manage stress
• Treat medical conditions early
Although hair loss can be frustrating, many cases improve once the underlying cause is identified and treated.
