Can Lichen Planopilaris Relapse After Stopping Treatment?

Yes, lichen planopilaris (LPP) can become active again after your symptoms have settled down and you reduce or stop your medication. Because LPP causes permanent hair loss if left unchecked, doctors often prefer a cautious approach when adjusting treatments that are currently keeping your condition under control.

The main goal of treatment is to control active inflammation and preserve your remaining hair follicles; treatments cannot regrow hair in areas where scarring has already occurred ^[1].

Understanding the Risk of Relapse

It is difficult to predict exactly who will experience a flare-up or when it might happen. In one retrospective study looking at patients with LPP and a related condition called frontal fibrosing alopecia, about 29% of patients experienced a clinical flare-up after stopping their treatment ^[2]. Another retrospective study looking at patients whose LPP had stabilized or slowed found that, on average, a recurrence of symptoms or hair loss happened about 1.8 years later ^[3].

Achieving “complete remission”—which means no detectable active inflammation or new hair loss—is possible but takes time. One study of LPP patients found that for those who reached complete remission, it took an average of 46 months of treatment ^[4].

It is important to remember that these numbers are averages from specific studies and do not predict your individual timeline. Because the timeline varies so much, ongoing monitoring is essential even when you feel your disease is quiet.

Adjusting Medication

Depending on the specific medication, your dose, and how long you have been taking it, your dermatologist may gradually reduce your dose over time (called a taper) or stop it entirely ^[5][2].

There is no single rule for all LPP treatments. For instance, gradual reduction is sometimes used for safety (such as with oral corticosteroids), or as a way for your doctor to carefully observe if the inflammation stays controlled at lower doses ^[5][2].

Do not stop or change your systemic medication without asking your prescribing clinician. Abruptly stopping without medical supervision can put your remaining hair at risk or cause drug-specific safety issues.

Maintenance Treatment and Ongoing Monitoring

Because ongoing active inflammation can lead to additional permanent hair loss, your doctor may recommend a maintenance strategy. This is individualized to your specific situation and may involve staying on a low dose of a systemic medication, or using a topical treatment (applied directly to the scalp) ^[1].

Even if you stop medication completely, your care team will want to continue monitoring your scalp. You cannot always feel when LPP is active; inflammation can occur without symptoms, and conversely, itching or redness can have causes other than LPP. Therefore, self-monitoring does not replace regular dermatologic examinations. Your doctor will look for signs of returning inflammation using a combination of methods:

• Symptom checks: Asking about returning itchiness, burning, or tenderness ^[6][5].
• Trichoscopy: Using a special magnifying tool to look closely at your scalp for redness or scale around the hair follicles ^[6][5].
• Photographs: Taking standard pictures to track any subtle spread of hair loss over time ^[6][5].

When to Contact Your Dermatologist

If you notice new or spreading patches of hair loss, increased shedding, persistent burning or tenderness, or new scale around your hair follicles, contact your dermatologist promptly. They can review your symptoms and determine whether your treatment plan needs to be restarted, increased, or changed ^[5][1].
