What is Scalp Hair Shedding?

The scalp has about 100,000 hairs. These hairs go through growing, resting, falling out, and regrowing. Losing 50 to 100 hairs a day is normal.

Hair Growth Cycle and Normal Hair Loss

The hair growth cycle has three main phases:

Anagen (growth) phase: This phase accounts for 80-90% of hair follicles and lasts 2-6 years.
Catagen (transition) phase: This phase accounts for 5% of hair follicles and lasts about 2-3 weeks.
Telogen (resting) phase: This phase accounts for 10-15% of hair follicles and lasts about 3 months before the hair is shed.

During the exogen phase, 50-100 hairs are shed per day. This is a normal part of the hair growth cycle.

Signs and Symptoms of Excessive Shedding

If the hair growth cycle is disrupted, hair may fall out faster. Signs of excessive hair shedding include:

Gradual thinning on top of the head
Circular or patchy bald spots
Sudden loosening of hair
Full-body hair loss

Sudden or patchy hair loss means you might have a medical issue that needs attention.

“Typically, 50–100 hairs are shed each day, depending on combing and washing routines.”

Hair Growth Phase	Duration	Percentage of Hair Follicles
Anagen (Growth)	2-6 years	80-90%
Catagen (Transition)	2-3 weeks	5%
Telogen (Resting)	3 months	10-15%

Causes of Scalp Hair Shedding

Hair loss can come from many sources. These include genetics, hormonal shifts, and medical issues. Knowing why hair falls out is key to fixing the problem.

Hormonal Imbalances and Medical Conditions

Hormonal changes, like those during pregnancy or menopause, can cause hair loss. Thyroid problems, such as too little or too much thyroid hormone, also lead to hair shedding. Besides, conditions like alopecia areata and scalp infections can cause hair to fall out.

Hormonal changes during pregnancy, childbirth, and menopause
Thyroid disorders (hypothyroidism and hyperthyroidism)
Alopecia areata, an autoimmune condition
Scalp infections

Medical issues like polycystic ovary syndrome (PCOS) can also cause hair loss. Some medicines, especially those for cancer, can make hair fall out too.

Seeing a doctor is crucial. They can find out why hair is falling out and help fix it.

Types of Hair Loss

Hair loss is a common concern that can take various forms. The most prevalent types of hair loss include:

Androgenetic alopecia – Also known as male or female pattern baldness, this is the most frequent type of hair loss, affecting up to 50% of individuals by the age of 50.
Telogen effluvium – Excessive shedding triggered by physical or emotional stress, hormonal changes, or medical conditions.
Anagen effluvium – Rapid hair loss caused by medical treatments such as chemotherapy or radiation therapy.
Alopecia areata – An autoimmune condition that results in patchy hair loss, which can sometimes lead to total hair loss.

Other less common types of hair loss include tinea capitis (scalp ringworm) and various forms of cicatricial alopecia (scarring hair loss). The cause, severity, and prognosis of hair loss can vary significantly. This highlights the importance of seeking professional medical advice for proper diagnosis and treatment.

“Hair loss can be a distressing and complex issue, but understanding the different types and their causes is the first step towards effective management.”

Scalp Hair Shedding and Its Impact

Excessive scalp hair shedding can greatly affect how someone looks and feels about themselves. It can cause anxiety, depression, and make people withdraw from social activities. Getting medical help and support is key to dealing with these feelings.

Research shows that male hair loss affects 30-50% of men by age 50. Most of this is due to genetics. The FDA has approved treatments like topical minoxidil and oral finasteride. Hair transplantation can also be very effective, with a success rate over 90%.

Hair loss can really affect a person’s mental health. Men who lose their hair may feel sad, anxious, and struggle to connect with others. They might also face a higher risk of heart disease, making early treatment even more important.

“Negative self-perception of balding patients has a significant psychological impact.”

Women can also experience hair loss, often in their 40s or later. Conditions like alopecia areata and telogen effluvium can cause hair shedding. These issues can also affect a person’s mental health.

Understanding the impact of hair shedding and getting medical care can help. It can improve how someone feels about themselves and their overall well-being.

Conclusion

Understanding why we lose hair is key to managing it better. Some hair loss is hereditary, but we can still take steps to help. We can prevent or manage some types of hair shedding.

Being gentle with our hair and protecting it from UV rays helps a lot. Also, treating any health issues or nutritional problems is crucial. Working with doctors to create a treatment plan can make a big difference in keeping our hair healthy.

It’s also important to deal with the emotional side of hair loss. Losing hair can affect how we feel and how we interact with others. Counseling and therapy can help those dealing with hair loss. They offer support and tools to face this challenge.
