Understanding alopecia
“Alopecia” simply means hair loss — but the word usually refers to its autoimmune and medical forms. Understanding which form you have is the first step to feeling in control again.

Alopecia areata
The immune system mistakenly targets hair follicles, causing round, smooth bald patches — on the scalp, sometimes brows, lashes or beard. It affects roughly 2% of people at some point, often starting young. Important truths: it is not caused by stress alone, not contagious, and not your fault. The follicles are not destroyed — which is why regrowth, even after years, remains possible.
Alopecia totalis and universalis
When areata progresses to the whole scalp (totalis) or the whole body including brows and lashes (universalis). Rarer, and emotionally heavier — the community around this matters as much as the medicine.
Androgenetic alopecia
The common genetic “pattern” loss — gradual, hormone-related, very different in character from areata. We cover it in everyday language on our sister platform hairloss.ph.
Scarring (cicatricial) alopecias
A group of conditions where inflammation permanently scars follicles — including forms that particularly affect women of colour (like CCCA) and frontal fibrosing alopecia. Early dermatological care can halt progression, which is why persistent itching, burning or shiny smooth patches deserve prompt attention.
What a dermatologist can do
- Confirm the diagnosis — trichoscopy and, if needed, a small biopsy distinguish the forms reliably.
- Discuss treatment options — these depend on the form, extent and your health; they range from topical and injected approaches to newer systemic medicines for severe areata. What is right for you is a medical conversation, not an internet list.
- Monitor and adjust — alopecia courses change, and so should plans.
