Scarring Alopecia

What Is Scarring Alopecia?

Scarring alopecia, also known as cicatricial alopecia, is a broad term describing a group of disorders in which hair follicles are permanently damaged and replaced by scar tissue.

Unlike non-scarring forms of hair loss, the affected follicle loses its ability to produce new hair once destruction is complete.

This makes early recognition particularly important: treatment is usually focused on protecting follicles that remain rather than attempting to regrow hair from follicles that have already been lost.

Scarring Alopecia Is Not One Condition

There are several different forms of scarring alopecia, each with its own pattern, underlying process and management requirements.

Conditions include:

• Frontal Fibrosing Alopecia (FFA)
• Central Centrifugal Cicatricial Alopecia (CCCA)
• Lichen Planopilaris (LPP)
• Folliculitis Decalvans
• Discoid Lupus affecting the scalp
• Dissecting Cellulitis of the scalp
• Other inflammatory or traumatic causes of follicular destruction

Some primarily involve lymphocytic inflammation, while others involve different inflammatory pathways. Identifying the underlying condition can therefore influence medical management.

Signs That Hair Loss May Be Scarring

The appearance varies according to the underlying condition, but warning signs can include:

• Smooth areas where follicular openings are no longer visible
• Progressive localised hair loss
• Redness around follicles
• Persistent scalp scaling
• Burning or itching
• Pain or tenderness
• Pustules or crusting
• Hair tufting
• Changes in scalp colour or texture

Not everybody experiences obvious symptoms, and some scarring alopecias can progress relatively quietly.

For this reason, unexplained progressive or unusual hair loss should not automatically be assumed to be ordinary pattern thinning.

Why Early Assessment Matters

Once the hair follicle has been irreversibly destroyed, natural regrowth from that follicle is no longer possible.

The objective of medical management is therefore often to identify the cause, control inflammatory activity and prevent further loss.

An earlier diagnosis may preserve more viable hair than waiting until extensive permanent loss has developed.

Assessment and Investigation

Scarring alopecia often requires more detailed investigation than straightforward pattern hair loss.

Assessment may include:

• Detailed examination of the scalp
• Digital trichoscopy
• Evaluation of follicular openings
• Identification of redness, scale or inflammation
• Review of symptoms
• Medical history
• Assessment of the pattern and rate of progression

Where scarring alopecia is suspected, YT Medical may recommend onward assessment by an appropriate medical or dermatology specialist.

In some cases, a scalp biopsy is needed to establish the precise form of scarring alopecia and guide management.

Treatment Depends on the Cause

There is no universal treatment for scarring alopecia.

Management depends on the particular condition, whether inflammatory disease remains active, how rapidly it is progressing and how much viable hair remains.

Medical treatment may be required to control the underlying inflammatory process.

Hair-growth or regenerative treatments should not be presented as substitutes for controlling active scarring disease.

The priority is always to protect remaining follicles wherever possible.

Restoring Hair After Scarring Alopecia

Once a condition has become appropriately controlled or inactive, patients may wish to explore ways of managing areas of permanent hair loss.

Options may include:

Hair Replacement

Medical wigs, toppers, hair systems and other non-surgical options can provide immediate coverage without relying on damaged follicles.

Hair Transplantation

Hair transplantation may be considered for some stable forms of scarring alopecia, but suitability must be assessed very carefully.

Because inflammatory disease can potentially reactivate and damage transplanted follicles, outcomes are less predictable than transplantation undertaken for stable male or female pattern hair loss. BAD specifically notes this consideration in conditions such as LPP.
