Managing Patients With Alopecia

What does the patient need to know at the first visit?

When I communicate with alopecia patients at the first visit, I make sure they know that I’m there to help them—that I won’t minimize their concerns and that I understand how important their condition is to them. Alopecia can be frustrating for both the patient and the physician, and there often is a confounding background of psychosocial stress and/or a history of physicians who have dismissed the patient’s concerns about his or her hair loss as trivial. Establishing an effective doctor-patient relationship is key in treating alopecia. Physicians sometimes may be left feeling like the patient wants to keep them in the room until his or her hair regrows, but in reality you simply need to reassure the patient that you are comfortable with the evaluation and treatment of alopecia and that several steps will be required but you will get started today.

How do you use punch biopsies to determine the best treatment options?

My most important tips regarding alopecia diagnosis relate to scalp biopsies, which usually are required in distinguishing chronic cutaneous lupus erythematosus from other scarring alopecias. First, an absorbable gelatin compressed sponge is your best friend. A small strip inserted into the punch biopsy wound results in prompt hemostasis without the need for sutures, and the resulting scar often looks as good or better than that produced by suturing. Next, don’t biopsy the active advancing borders of an alopecia patch, as the findings usually are nonspecific. Instead, biopsy a well-established portion that has been present for at least 4 to 6 months but is still active. In inconclusive cases, a biopsy of a scarred area stained with Verhoeff elastic stain can demonstrate characteristic patterns of elastic tissue loss and often establish a diagnosis. It is important to distinguish chronic cutaneous lupus erythematosus from other forms of scarring alopecia, as it is more likely to respond to antimalarials.

What are your go-to treatments? Are your recommendations anecdotal or evidence based?

There isn’t an extensive arsenal of evidence-based therapy for refractory scarring alopecia, but that doesn’t mean we don’t have effective therapies; it simply means that our treatments are based on experience without accompanying randomized controlled trials. We need to produce more evidence, but patients with severe disease still need to be treated in the meantime. It’s important to remember that therapeutic complacency can result in permanent irreversible scarring. The presence of easily extractable anagen hairs is a sign of active disease. This simple test is helpful to monitor therapeutic progress.

Topical and intralesional corticosteroids can be extremely useful and often are underused. In general, the risk of scarring and atrophy from untreated disease is much greater than that from the corticosteroid. On the scalp, atrophy often presents as erythema, which should not be confused with erythema related to active disease. Dermoscopy is useful to demonstrate that the redness represents dermal atrophy with prominence of the subpapillary plexus of vessels.

When systemic therapy is required, antimalarials, retinoids, dapsone, thalidomide, sulfasalazine, mycophenolate mofetil, and methotrexate have all been used successfully in the setting of cutaneous lupus erythematosus, while topical tazarotene and topical calcineurin inhibitors are generally disappointing.

For the treatment of lichen planopilaris, intralesional corticosteroids, oral retinoids, and excimer laser can be effective. In contrast, antimalarials usually are not effective in preventing disease progression. The peroxisome proliferator-activated receptor-γ agonist pioglitazone can be effective, but reported results vary widely. In my experience, mycophenolate mofetil is generally reliable in patients with refractory disease. Dutasteride can be effective as a first-line therapy in the setting of frontal fibrosing alopecia, although some of the noted improvement may relate to the nonscarring portion of the disease in patients with a background of pattern alopecia.

How do you keep patients compliant with treatment?

Again, the key to treatment compliance is to establish an effective doctor-patient relationship. Whenever possible, begin with adequately potent therapy to give patients an early response. Don’t hesitate to use prednisone initially for inflammatory scarring alopecia. Patients need to see signs of progress in order to stay compliant with treatment, and long trials of ineffective therapies destroy trust. Adequate doses of intralesional or oral corticosteroids often are appropriate to ensure an early response with subsequent transition to steroid-sparing agents.

What do you do if they refuse treatment?

Try to find out why—often it’s simply fear of side effects. Patient education is key, and it can help tremendously to share with them the number of patients you have treated safely with the medication in question and assure them that you know how to monitor for the important side effects.
