What are the causes of excessive hair loss? It’s a common concern that may affect both men and women at different stages of life. Noticeable hair shedding may indicate that something is affecting the normal hair growth. In this guide we’ll understand the main causes of excessive hair loss and top tips for preventing hair loss.
The Concept of Excessive Hair Loss
Excessive hair loss refers to shedding more than usual (>100 hairs per day) often resulting in noticeable thinning of hair or visible areas of the scalp. It may occur temporarily or persist over time, depending on the underlying cause.
Understanding what excessive hair loss means and how it differs from normal daily shedding helps you recognize the problem early and follow the suitable hair loss remedies.
What Are the Causes of Excessive Hair Loss?
The causes of excessive hair loss vary from one case to another depending on several factors, health conditions, and lifestyle habits which include:
Poor Nutrition and Restrictive Diet
Healthy hair growth depends on adequate protein, vitamins, and essential minerals, so poor nutrition or following a restrictive diet can deprive hair follicles of the nutrients they need, leading to weaker hair and increased shedding.
Hereditary Hair Loss
Genetics can play a major role in hair loss. Some people inherit weak hair follicles that develop thinning and hereditary hair loss over time.
Hormonal Changes
Hormonal imbalance can affect normal hair growth cycle, especially during certain stages of life. The effect of these changes varies from case to another and may lead to temporary noticeable hair loss.
Nutrient and Vitamins Dificiencies
A deficiency in essential nutrients can affect hair growth and density. Also low levels of some vitamins such as vitamin D and B complex may cause increased hair shedding and weaker hair.
Thyroid Disorders
Thyroid hormones are in several important body functions including normal hair growth cycle. Both Hypothyroidism and overactive thyroid can interfere with hair growth and cause excessive shedding.
Stress and Sleep Disorders
Prolonged stress and sleep disorders can disrupt hair growth cycle and trigger a type of hair loss called Telogen Effluvium. There’s also a behavioral disorder called Trichotillomania, in which a person repeatedly pulls out their hair leading to hair loss.
Some Diseases and Health Conditions
Some autoimmune diseases such as Alopecia Areata may cause severe hair loss, as well as some chronic digestive conditions may interfere with proper nutrient absorption.
Scalp Problems
Recurring scalp inflammation, dandruff, and certain skin problems may negatively affect hair health and increase shedding.

Does Dandruff Cause Hair Loss?
Dandruff doesn’t usually cause hair loss directly. However, it can affect the health of the scalp and cause itching, irritation, and inflammation. Frequent scratching may damage the scalp and contribute to hair breakage or increased shedding.
For this reason, treating dandruff and maintaining a healthy scalp can help reduce factors that may worsen hair loss.

Rapid weight loss and a restrictive diet can deprive the body of essential nutrients. This may interfere with the normal hair growth cycle and increase shedding. Losing weight gradually while following a balanced diet is a healthier approach.
5.Reduce Heat and Chemical Treatments
Frequent heat styling, hair dyes, and chemical treatments may weaken your hair shaft and increase breakage. Try to limit these treatments and avoid excessive heat to reduce hair damage.
