Hair Loss Conditions

Alopecia

First, let's get some terminology out of the way. Alopecia just means "hair loss" from areas where hair usually grows. It isn't on its own a diagnosis and doesn't really help us figure out possible causes, it's just a descriptive term. There are many different types of alopecia, some that people are born with (congenital) and many more that develop later (acquired).

What Does Alopecia Look Like?

Asking what alopecia looks like is a bit like asking, "What do people look like?" The truth is, there is a vast spectrum of appearances among those affected by hair loss. Some individuals may appear to have luscious, long flowing locks, while others may have no hair at all anywhere on their body.

Alopecia ("hair loss") includes:

Thinning Hair: This leads to a noticeable decrease in hair density and increasing scalp show
Receding Hairlines: Particularly in the temporal region, as hair follicles are lost, the hairline can creep back
Balding Patches: Patches of hair loss, which can vary in size and location.
Complete Hair Loss

Both full and partial hair loss can have a significant emotional impact and the psychological effects can be profound, regardless of the extent of hair loss. Consider this: the woman with long, beautiful hair may have strategically parted her hair to conceal a patch the size of an egg where no hair is present. Alopecia is not always visible at first glance.

Alopecia can affect anyone, regardless of age, gender, or background. It’s a condition that often requires understanding and compassion, both from those who experience it and from their loved ones. By fostering awareness and empathy for sufferers of all types of alopecia, we can create a supportive environment for those navigating the challenges of hair loss.

An Overview of Common Aquired Hair Loss Conditions

This page will try to give an overview of common acquired hair loss conditions, supported by scientific research.

For each condition, we will summarise an evaluation of the current evidence for the effectiveness of various therapies.

1. Androgenetic Alopecia

What is Androgenetic Alopecia?

Androgenetic Alopecia is the most common form of hair loss in both men and women. It is characterized by a gradual thinning of hair, often beginning at the temples and crown in men, and diffuse thinning across the scalp in women. This condition is primarily influenced by genetic factors and hormonal changes, particularly the effects of dihydrotestosterone (DHT) on hair follicles.

2. Telogen Effluvium

Telogen Effluvium is a temporary hair loss condition that occurs when a significant number of hair follicles enter the resting phase prematurely. This can be triggered by stress, hormonal changes, illness, or certain medications. Individuals may notice increased hair shedding, often several months after the triggering event.

3. Alopecia Areata

Alopecia Areata is an autoimmune disorder that causes sudden hair loss in patches. The immune system mistakenly attacks hair follicles, leading to hair loss on the scalp and other areas of the body. While the exact cause is unknown, it can be associated with other autoimmune disorders.

4. Traction Alopecia

Traction Alopecia is caused by prolonged tension on hair follicles due to certain hairstyles, such as tight ponytails or braids. This condition is preventable and reversible if caught early, but prolonged tension can lead to permanent damage.

5. Hair Pulling Disorder (Trichotillomania)

Compulsive hair pulling can accompany anxiety.

6. Scarring Alopecias

Scarring alopecias, or cicatricial alopecias, involve the destruction of hair follicles and replacement with scar tissue. This can result from inflammatory skin conditions, infections, or injuries. Conditions such as Lichen Planopilaris and Frontal Fibrosing Alopecia fall into this category.
