What are the Different Types of Alopecia and How to Treat Them

Hair loss has a way of announcing itself when you least expect it, and the causes can be as varied as the strands falling onto your pillow. From the sudden bald patches of alopecia areata to the slow, relentless thinning of androgenetic alopecia, the types of alopecia often leave you with more questions than answers. And let’s be honest—“hair loss” is a deceptively simple term for a condition that can feel anything but simple.

But not all alopecia is the same. Some types of alopecia are reversible with the right treatment, while others might require a more permanent solution. Yet, most people who experience hair loss end up chasing generic remedies, only to find that their results are as patchy as their hairline. That’s because each type of alopecia requires a tailored approach rooted in understanding its unique causes and triggers.

So, What Actually is Alopecia?

Alopecia is the catch-all diagnosis for hair shedding that goes way beyond the usual stray strands on your brush. While everyone loses 50–100 hairs daily (don’t worry, that’s normal), alopecia signals something more significant, like your body waving a red flag that something is out of balance. Whether it’s your genes, hormones, or even lifestyle choices quietly sabotaging your hairline, alopecia requires attention—and fast.

Here’s the thing: not all hair loss is the same. Telogen effluvium, for instance, is one of the most common types of hair shedding. It’s triggered by stress, illness, or sudden changes like crash dieting. This condition pushes more hairs than usual into the resting phase (telogen), causing diffuse thinning that can make you feel like you’re shedding faster than a Labrador in summer.

Alopecia can also stem from autoimmune responses, as seen in alopecia areata, or hormonal shifts, like those driving androgenetic alopecia (aka pattern baldness). Then there are lifestyle-induced triggers like tight hairstyles (traction alopecia) or medical conditions that wreak havoc on your scalp health. It’s a complex web, but one thing’s for sure: alopecia is your body’s way of saying, “Hey, something’s up.”

7 Common Types of Alopecia

Alopecia isn’t a one-size-fits-all condition—it comes in various forms, each with its own unique causes, symptoms, and challenges. Whether it’s patchy hair loss caused by your immune system acting out or thinning triggered by hormonal shifts, understanding these types can help you identify the right approach to treat them effectively.

1. Alopecia Areata

Alopecia areata is the overachiever of autoimmune conditions—your immune system mistakenly attacks your hair follicles as if they’re intruders. The result is patchy bald spots that can show up overnight, leaving you wondering why your immune system is being so dramatic.

Causes & Symptoms:

Stress, genetics, or an underlying autoimmune disorder can all play a role in triggering alopecia areata. Symptoms include smooth, round patches of hair loss, often starting on the scalp but potentially appearing elsewhere.

2. Androgenetic Alopecia (Pattern Hair Loss)

This affects millions of men and women worldwide. Often referred to as male or female pattern baldness, androgenetic alopecia is your genetics teaming up with the hormone DHT (dihydrotestosterone) to shrink your hair follicles over time.

Causes & Symptoms:

A hereditary predisposition is the main culprit here. For men, it often starts with a receding hairline, while women experience overall thinning, particularly around the crown.

3. Traction Alopecia

If your scalp could talk, traction alopecia would be its plea for mercy after years of tight hairstyles. High ponytails, braids, extensions, or even man buns can cause repeated tension on the scalp, leading to gradual hair loss.

Causes & Symptoms:

Persistent pulling damages the hair follicles, resulting in thinning along the hairline or areas of scalp tenderness. Left unchecked, the damage can become permanent.

4. Telogen Effluvium

Stress doesn’t just take a toll on your mind—it can throw your hair growth cycle into chaos, too. Telogen effluvium occurs when a sudden shock to the system—think illness, extreme stress, or hormonal shifts—pushes more hairs than usual into the resting (telogen) phase.

Causes & Symptoms:

This type of alopecia leads to diffuse thinning across the scalp, often noticeable when brushing or washing your hair. The good news is it’s typically temporary.

5. Scarring Alopecia

Also known as cicatricial alopecia, this form of hair loss doesn’t just stop follicle activity—it destroys the follicles entirely, replacing them with scar tissue. Scarring alopecia is like the villain of hair loss, and it means business.

Causes & Symptoms:

It’s often linked to inflammation from autoimmune disorders or infections. Symptoms include scalp redness, itching, or pain, followed by permanent hair loss in affected areas.

6. Alopecia Totalis

Think of alopecia totalis as alopecia areata leveling up—it involves the complete loss of all scalp hair. Your immune system is still the prime suspect here, but the extent of the damage is far greater.

Causes & Symptoms:

The most obvious symptom is a completely bald scalp, but it may also be accompanied by brittle or thin nails, signaling an autoimmune component.

Recovery Potential:

While alopecia totalis isn’t always permanent, its reversibility varies widely between individuals. Some people experience regrowth with treatments like corticosteroids, immunotherapy, or newer options like JAK inhibitors, while others may not see a full recovery. Early intervention often improves the chances of hair regrowth.

7. Alopecia Universalis

When alopecia goes all-in, it’s called alopecia universalis. This severe form causes total loss of all body hair—not just your scalp, but eyebrows, eyelashes, and everything in between.

Causes & Symptoms:

This condition is typically linked to autoimmune dysfunction, where your immune system mistakenly targets hair follicles. Symptoms include the complete absence of body hair, often accompanied by emotional and physical impacts.

Recovery Potential:

Alopecia universalis is considered one of the most challenging types of alopecia to treat. While it is frequently permanent, some individuals respond to advanced treatments like JAK inhibitors or immunotherapy. However, results vary greatly, and widespread regrowth remains rare without early and aggressive intervention.

Treatments for Different Types of Alopecia

When it comes to treating alopecia, one size definitely doesn’t fit all. The effectiveness of any treatment hinges on the type of alopecia you’re dealing with and what’s causing it. Whether it’s androgenic alopecia slowly thinning your crown or alopecia totalis wiping out your scalp hair entirely, tackling hair loss requires a targeted, science-backed approach that doesn’t waste time—or hair.

1. Minoxidil (Topical Solution)

Minoxidil, available as a foam or liquid, is often the go-to treatment for androgenic alopecia. It works by improving blood flow to hair follicles and encouraging them to enter the growth phase. However, it requires consistent, lifelong use to maintain results.

  • Best for: Androgenic alopecia and telogen effluvium. Patience is key; noticeable results may take 4–6 months.

2. Finasteride (Oral Medication)

Finasteride takes on DHT (dihydrotestosterone), the hormone responsible for shrinking hair follicles in androgenic alopecia. By blocking DHT, it prevents further hair loss and, in some cases, encourages regrowth. While effective, it comes with potential side effects, so consult your doctor before starting.

  • Best for: Androgenic alopecia in men. Not recommended for women due to hormonal risks and absolutely not prescribed to pregnant women or women trying to become pregnant, as it can cause serious birth defects.

3. Corticosteroid Injections or Topicals

For autoimmune types like alopecia areata or alopecia totalis, corticosteroids can suppress the immune system's attack on hair follicles. This helps reduce inflammation and may stimulate regrowth.

  • Best for: Alopecia areata and alopecia totalis. Results vary widely, and relapses are possible.

4. Platelet-Rich Plasma (PRP) Therapy

PRP involves injecting your own plasma, rich in growth factors, into your scalp to stimulate hair follicles. It’s a newer treatment that shows promise for several types of alopecia, especially androgenic alopecia and alopecia areata.

  • Best for: Androgenic alopecia and alopecia areata. Success rates vary, with some studies reporting as low as 15% improvement in hair density, making it a less predictable option.

5. Low-Level Laser Therapy (LLLT)

Devices like laser hair helmets use specific wavelengths of light to stimulate hair follicles and promote regrowth. LLLT is non-invasive, safe, and can be combined with other treatments like Minoxidil or PRP to amplify results.

  • Best for: Androgenic alopecia, telogen effluvium, and even alopecia areata. The lasers increase cellular activity in dormant follicles without causing heat damage.

6. Lifestyle Changes and Nutritional Support

Diet and stress management play a significant role in certain types of alopecia, particularly telogen effluvium. Nutrient deficiencies, such as iron or biotin, can exacerbate hair loss.

  • Best for: Telogen effluvium and cases linked to poor nutrition. Load up on leafy greens, lean proteins, and foods rich in iron, zinc, and biotin.

7. Hair Transplant Surgery

For severe cases of androgenic alopecia or scarring alopecia, hair transplant surgery offers a permanent solution. This procedure involves moving hair follicles from a healthy area of your scalp to the thinning or balding spots.

  • Best for: Advanced androgenic alopecia and scarring alopecia. To improve outcomes and minimize graft failure, combining hair transplant surgery with Low-Level Laser Therapy (LLLT) is often recommended, as LLLT can enhance graft survival and stimulate additional hair regrowth. It’s also worth noting that this procedure is expensive and requires a highly skilled surgeon.

8. Emerging Treatments: JAK Inhibitors

JAK inhibitors, a class of drugs originally developed for autoimmune conditions, have shown promise in treating severe cases like alopecia totalis and alopecia universalis. Though still under study, they offer hope for conditions previously considered untreatable.

  • Best for: Alopecia totalis and alopecia universalis. Availability is limited, and more research is needed.

Conclusion

Alopecia isn’t a one-size-fits-all condition—it’s a spectrum that ranges from temporary shedding to permanent loss, like scarring alopecia. The good news is early diagnosis and targeted treatments can make all the difference. Whether it’s addressing autoimmune triggers, halting hormonal imbalances, or repairing follicular damage, understanding the root cause is key. Ignoring the problem only gives it more time to worsen.

Don’t wait to take action. The sooner you pinpoint the type of alopecia you’re dealing with, the sooner you can start regaining not just your hair but also your confidence.
