Ever wonder what's really going on with hair loss? Let’s talk about alopecia—the medical term for hair loss—a surprisingly common condition that can affect people of all ages and genders. But what is alopecia and what causes it?

Far from a simple disappearing act, alopecia is a complex biological condition. While it’s not unreasonable to expect your hair to stay on your head, all the hoping and wishing won’t stop this complicated, over-dramatic family of conditions.

Despite how stressful thinning hair and hair fall can be, understanding the science behind the different types of alopecia and their causes can help you feel more in control.

Types of Alopecia

Who knew hair loss had a type? Apparently, it’s not just one, either—it’s an entire party of them! So, how many types of alopecia are there? While there are over 100 different types, they are divided into two main categories: non-scarring and scarring.

Non-scarring alopecia is often reversible and has a better prognosis than scarring alopecia because, in this subtype, the hair follicle is still alive and can regrow. In contrast, scarring alopecia is where the follicle is destroyed and replaced with scar tissue, resulting in permanent loss. Fortunately, it is less common, accounting for roughly 3-7% of cases.

Nonscarring Alopecia

This less permanent form of hair loss is classified into several main, well-recognized types. Here's a breakdown:

Androgenetic Alopecia (Genes + Hormones)

What is androgenetic alopecia? This most common form of hair loss, also known as male or female pattern hair loss, simply refers to hair loss caused by a combination of genetics and hormones doing their thing. This is the one where you can thank your family for your many talents and a questionable hairline.

In people with a genetic predisposition, hair follicles have a high density of androgen receptors. When DHT binds to these receptors, it triggers a "miniaturization" signaling pathway.

The growth phase (anagen) is shortened, and the resting phase (telogen) is lengthened. With each cycle, the follicle physically shrinks, producing a hair that is thinner, shorter, and less pigmented (turning from "terminal" hair into "vellus" hair) until, without intervention, the follicle eventually becomes dormant.

In men, it often starts above the temples and on the crown. In women, it typically presents as gradual, diffuse thinning across the top of the scalp, with a widening part and the hairline usually intact.

Alopecia Areata (The Autoimmune Curveball)

Alopecia areata is actually an autoimmune condition in which your body's immune system gets a little mixed up and decides your hair follicles are the bad guys. A combination of genetic susceptibility (often linked to the HLA gene complex) and an environmental trigger (like a virus or severe stress) is to blame. (But, we're not pointing fingers!)

With this type of hair loss, your body's own defense system attacks healthy hair follicles, causing hair to suddenly fall out in smooth, round, or oval patches on the scalp or body. As white blood cells (CD8+ T-cells) mistakenly identify the bulbs as foreign invaders, they swarm the area and release inflammatory cytokines. This inflammation forces the hair follicle into an immediate resting state, causing the hair to fall out in patches, though the follicle itself remains alive.

What are the different types of alopecia areata? Unfortunately, there are more severe forms that don’t stop at isolated patches on the scalp.

• Alopecia Totalis: What is alopecia totalis? “Totalis”, a Latin-derived medical term, sums this condition up as it refers to a total loss of all scalp hair.
• Alopecia Universalis: What is alopecia universalis? This most severe form of alopecia areata involves the loss of all facial and body hair, including the eyebrows and eyelashes. Those with alopecia universalis may also notice brittleness, small pits, or a rough, sandpaper texture on their nails, as well.

Telogen Effluvium (The Stress-Shed)

What is telogen effluvium? You know those weeks where you feel like you're running on fumes? Your hair feels it too. Telogen effluvium hair loss, or stress alopecia, is a systemic reaction (vs. a localized scalp issue) triggered by major physical or emotional stressors.

When the body undergoes a major shock—high fever, severe nutritional deficiency, childbirth, or extreme emotional trauma—it enters "survival mode," setting the stage for this shedding. These significant stressors cause hair follicles to prematurely enter the resting (telogen) phase of the growth cycle well ahead of schedule.

The body deprioritizes non-essential functions, such as hair production. It releases a surge of cortisol, which can act as a biological signal to prematurely push up to 30% of active hair follicles into the telogen (shedding) phase at once.

About 3 months after the trigger, a massive "effluvium" (outflow) of hair occurs.
Fortunately, this type is often temporary. If the triggering event is resolved, hair may regrow within about six months. A little patience here can ease the process.

Traction Alopecia (A Styling Problem)

No, your hair isn’t staging a walkout because it’s mad your hairstyle is outdated. But your hair loss could be a reaction to how you treat it.

So, what is traction alopecia? This form of hair loss is caused by excessive pulling over an extended period, due to tight hairstyles such as braids, ponytails, or extensions.
The constant mechanical micro-trauma of tension on the base of the hair follicles (dermal papilla) causes hair to fall out. If the pulling continues, it can cause low-grade chronic inflammation around the root, replacing the follicle with scarring (aka fibrotic tissue).

Scarring Alopecia (The Permanent Exit)

Also called cicatricial alopecia, this is a more serious category. Think of scarring alopecia as a permanent curtain call for the hair follicle, wherein inflammation permanently destroys it and replaces it with scar tissue, meaning the hair can't grow back.

Types of scarring alopecia:

• Central Centrifugal Cicatricial Alopecia involves hair loss that spreads outward from the center of the scalp.
• Frontal Fibrosing Alopecia appears as hair loss across the front of the scalp and eyebrows.

Additional Types of Alopecia

There are also unique types of alopecia tied to medical treatments and psychological conditions.

• Anagen Effluvium — Rapid hair loss caused by medical treatments like chemotherapy.
• Trichotillomania — A psychological condition characterized by the urge to pull out hair.

Alopecia Solutions

Now that you can answer the question that brought you here: what are the main types of alopecia and its causes, let’s dive into how CHARISMO helps make hair stay put.

While different types of alopecia have different "start" points (hormonal vs. physical stress), they all lead to the same endpoint: a weakened follicle and a shortened growth cycle. DEKOHAIR, our clinically proven hair loss serum, features ingredients that zero in on the biological triggers of alopecia, making it an effective tool for supporting hair preservation.

• Androgenetic thinning: Potent natural blockers inhibit the enzyme 5-alpha reductase. This reduces the conversion of testosterone into DHT (dihydrotestosterone) at the scalp level, helping prevent hair follicles from shrinking and allowing them to produce thicker, more robust terminal hair.
• Stress related alopecia: DEKOHAIR can help the scalp’s comeback from nutritional deficiencies and other stressful upheavals tied to telogen effluvium. Its vasodilator effect improves microcirculation, ensuring the "re-awakening" follicles have a surplus of nutrients and oxygen to transition hair from the resting phase into the growth phase more efficiently.
• Traction alopecia: For hair weakened by mechanical stress, the structural integrity of the follicle is key. DEKOHAIR’s proprietary blend of apigenin and oleanolic acid works to strengthen the basement membrane of the hair follicle and bolster extracellular matrix proteins, improving anchoring to help hair stay firmly rooted and reduce the rate of premature fall-out.
• Alopecia Areata: While autoimmune-related hair loss requires medical consultation, DEKOHAIR supports the recovery process by maintaining a healthy scalp environment. Its anti-inflammatory properties and protective ingredients help soothe the scalp and reduce "micro-inflammation", providing a stable foundation suitable for regrowth once the immune flare-up subsides.
