Different types of hair loss also indicate different causes of hair loss. There are many hair loss causes, some more obvious than others, and some are more easily addressed than others. Below you will find some of the most common reasons for hair loss.

Stress can cause a disruption of the Hair Growth Cycle, which can result in excessive shedding. Acute stress can present as sudden hair fall 4-16 weeks after the event that caused the stress, such as illness or an accident. The hair fall is often delayed for several weeks due to the natural duration of the Hair Growth Cycle. Chronic stress has also been shown to be a cause of a number of hair growth disruptions due to the overproduction of certain hormones. Stress has likewise been shown to precipitate a number of hair loss related conditions, including genetic hair loss, excessive shedding, known as Telogen Effluvium, patchy hair loss, known as Alopecia Areata and an OCD-related condition that makes the sufferers pull out their own hair, which is known as Trichotillomania.

Hormonal irregularities, giving birth and menopause can have a significant influence on hair growth and are common hair loss causes. Hormonal changes can lead to a disruption of the Hair Growth Cycle, which can present as hair fall during menopause or after giving birth. After giving birth, 40-50% of women experience hair loss due to hormonal changes because the hormones related to pregnancy have kept the hairs from falling out during pregnancy, meaning, after giving birth a disproportionate amount of hair is shed at once. Hormonal irregularities can occur after giving birth or can show as an irregular menstrual cycle, Polycystic Ovary Syndrome and symptoms related to menopause. Hormonal irregularities can contribute to genetic hair loss conditions and excessive shedding, such as Telogen Effluvium or Postpartum Effluvium.

Health and medicine can both influence hair growth. Certain illnesses are known to present with hair loss as a symptom, such as diabetes or thyroid problems, but other things, including high fever, infections and some autoimmune conditions can result in Telogen Effluvium, Cicatrical Alopecia or scarring hair loss. Beginning or ending a course of certain types of medication can also cause hair loss, however, such reactions are individual. The medications known to cause hair loss in some people include anti-depressants, thyroid medicine, contraceptive pills and chemotherapy.

Diet, smoking and everyday hairstyling habits also have an influence on the hair. To maintain healthy hair, it is important to have a healthy diet, meaning, one that is rich in protein, glucose and vitamins that are essential for healthy hair growth. Dieting and rapid weight loss can sometimes take a toll on the hair, because the hair is one of the last things to get nutrients in the body, which can show as Telogen Effluvium. Smoking impairs blood circulation, which can further influence the Hair Growth Cycle, and everyday hairstyling habits, along with chemical over-processing, can leave the hair brittle and prone to breakage.

Genetics is also a factor that should be considered when looking at hair loss reasons. Genetic hair loss can affect both men and women, but it is much more common in men. Male Pattern Baldness/Female Pattern Hair Loss are the conditions most commonly associated with genetic hair loss, but certain types of autoimmune conditions, such as Alopecia Areata, can also partly be caused by genetics.
