Hair loss shows up quietly at first. Maybe you notice a little thinning near your temples or a wider part line than usual. It’s easy to panic, but the truth is that hair loss comes in many different forms. Each type has its own cause, symptoms, and treatment path.
When you understand which type of alopecia you’re dealing with, it becomes much easier to find the right solution. Let’s walk through the main types and what triggers them.
1. Androgenetic Alopecia (Male & Female Pattern Baldness)
This is the most common form of hair loss. Genetics and hormones play the biggest role.
Common signs:
- Gradual thinning at the crown
- A slowly receding hairline
- Miniaturized, weaker strands
The hormone DHT shortens the growth cycle and makes follicles smaller over time.
2. Telogen Effluvium (Stress-Related Shedding)
This type happens when a large number of hairs enter the shedding phase at the same time.
Typical triggers:
- Ongoing stress
- Illness or infection
- Sudden weight loss or crash dieting
- Post-pregnancy shifts
- Thyroid problems
Once the trigger improves, hair usually recovers.
3. Alopecia Areata (Autoimmune Hair Loss)
In this condition, the immune system mistakenly targets hair follicles.
Recognizable signs:
- Smooth, round bald patches
- Sudden onset
- Hair loss on eyebrows or beard areas
It often comes in cycles or flare-ups.
4. Traction Alopecia (Hairstyle-Related Damage)
Constant pulling or tension on the scalp weakens hair follicles.
Common causes:
- Tight ponytails or buns
- Braids or weaves
- Extensions worn for long periods
Changing hairstyles early can prevent permanent damage.
5. Scarring Alopecia (Cicatricial Alopecia)
This type involves inflammation that destroys hair follicles permanently.
Possible causes:
- Severe infections
- Certain autoimmune conditions
- Chronic scalp inflammation
Early diagnosis is important because late-stage damage can’t be reversed.
6. Retrograde Alopecia (Hair Loss Starting from the Nape)
Retrograde alopecia is less common and often misunderstood.
It typically begins at the nape of the neck or the sides of the scalp and moves upward.

It has a different progression compared to typical pattern baldness and needs careful evaluation.
7. Anagen Effluvium (Chemical or Treatment-Related Hair Loss)
This type usually appears during exposure to strong medical treatments.
Common triggers:
- Chemotherapy
- Radiation therapy
- Harsh chemicals or toxins
Hair often regrows once treatment ends.
8. Nutritional Deficiency-Related Alopecia
When your body lacks essential nutrients, hair becomes weak and sheds easily.
Key deficiencies:
- Iron
- Vitamin D
- Zinc
- Protein
A simple blood test can confirm most of these.
Why Identifying the Type Matters?
Every type of alopecia responds differently to treatment. When people try random oils, supplements, or home remedies without knowing the real cause, progress becomes slow or unpredictable.
Dermatologists usually diagnose hair loss using:
- Scalp examinations
- Blood tests
- Tracheoscopy
- Medical history review
The earlier you figure out the type, the easier it becomes to treat or manage.
