Different Types of Hair Loss (Androgenetic Alopecia, Alopecia Areata, etc.)

Understanding Different Types of Hair Loss

Hair loss is a common concern that affects both men and women, impacting self-esteem and confidence. There are various types of hair loss, each with its unique causes and characteristics. In this article, we will explore the most common types of hair loss and shed some light on their key features.

Androgenetic Alopecia

Also known as male or female pattern baldness. Caused by a combination of genetic and hormonal factors. Characterized by gradual thinning of hair on the crown and temples in men and diffuse thinning in women.

Alopecia Areata

An autoimmune disorder that leads to patchy hair loss. The immune system mistakenly attacks hair follicles, causing hair to fall out in small, round patches. Can occur on the scalp and other areas with hair, like eyebrows and beard.

Telogen Effluvium

Triggered by significant physiological or emotional stress. Hair prematurely enters the resting phase (telogen) and sheds more than usual. Often temporary and reversible once the underlying cause is addressed.

Traction Alopecia

Caused by excessive tension on the hair due to tight hairstyles (e.g., ponytails, braids). Hair loss occurs in areas where constant pulling is experienced. Can be prevented by avoiding tight hairstyles and allowing hair to rest.

Anagen Effluvium

Usually drug-induced, such as chemotherapy or radiation treatment. Rapid loss of hair during the anagen (growth) phase. Hair follicles are affected, leading to severe hair loss.



A psychological disorder where individuals have an irresistible urge to pull out their hair. Results in patchy hair loss due to self-inflicted pulling. Behavioral therapy can be helpful in managing this condition.

Scarring Alopecia

Hair loss caused by permanent damage to hair follicles and replaced by scar tissue. Often associated with conditions like lichen planopilaris and folliculitis. Hair cannot regrow in affected areas.

Age-Related Hair Loss

As people age, hair growth slows down, and hair becomes thinner and more fragile. Common in both men and women but more pronounced in men (male pattern baldness).

Nutritional Deficiency-Induced Hair Loss

Lack of essential nutrients like iron, zinc, and biotin can contribute to hair loss. A balanced diet and supplementation can help improve hair health.

Hormonal Hair Loss (Postpartum Hair Loss)

Occurs after childbirth due to hormonal changes. A temporary condition and hair usually regrows after a few months. Understanding the various types of hair loss can help individuals identify the underlying causes and seek appropriate treatments or solutions. Consulting a dermatologist or hair specialist can provide personalized guidance for addressing hair loss concerns effectively.
