Management of Alopecia
Initial Approach: Counseling and Watchful Waiting
For patients with limited patchy alopecia areata of short duration (<1 year), reassurance and watchful waiting is the recommended first-line approach, as spontaneous remission occurs in up to 80% of cases without any treatment. 1
Essential Counseling Components
- Provide a thorough explanation of the disease nature, expected course, and available treatment options as the foundation of management 1
- Warn patients that regrowth cannot be expected within 3 months of any individual patch development 1
- Emphasize the critical limitation that while treatments may induce temporary hair growth, none have been shown to alter the long-term course of the disease 1
- Address psychological impact proactively, as alopecia can result in higher levels of anxiety, greater risk of depression, and social/work-related problems 1
- Connect patients with support groups and other patient experts to help cope with altered body image and find self-acceptance 1
When to Avoid Treatment
- Do not pursue aggressive treatment in patients with longstanding extensive alopecia, as prognosis is poor and a wig may be a better option than ineffective treatments 1
- Avoid hazardous treatments given that alopecia has no direct impact on general health that justifies their use, particularly when efficacy is unproven 1
Treatment Options When Intervention is Desired
For Limited Patchy Alopecia Areata
Intralesional corticosteroids (triamcinolone acetonide 5-10 mg/mL) are the most appropriate treatment for limited patchy hair loss and cosmetically sensitive sites like eyebrows. 1, 2
- Inject 0.05-0.1 mL just beneath the dermis in the upper subcutis, producing a tuft of hair growth about 0.5 cm in diameter 1
- Expect response in 62% of patients with fewer than five patches <3 cm in diameter, with effects lasting approximately 9 months 1
- Main limitation is patient discomfort from multiple injections 1
Topical Corticosteroids: Limited Evidence
- Very potent topical steroids (0.05% clobetasol propionate foam) are widely used but have limited evidence for effectiveness 1
- Folliculitis is a common side-effect of potent topical steroid treatment 1
- The British Association of Dermatologists advises against routine use due to lack of convincing evidence 2
For Extensive Alopecia Areata
Contact immunotherapy is the best-documented treatment for extensive disease, though it has less than 50% response rate and requires multiple hospital visits over months. 2
- Wigs provide immediate cosmetic benefit and should be offered as a practical option for extensive alopecia 2
For Androgenetic Alopecia
Topical minoxidil 2% solution twice daily is first-line treatment for women with androgenetic alopecia, which arrests progression rather than stimulates regrowth. 2, 3
- Oral finasteride is available as another treatment option specifically for male patients 2, 3
- Platelet-rich plasma (PRP) injections show promise with increased hair density, requiring repeated treatments every 6 months 2
Treatments to Explicitly Avoid
- Do not use systemic corticosteroids or PUVA for alopecia areata due to potentially serious side-effects and inadequate efficacy evidence 2
- Oral zinc and isoprinosine are ineffective in controlled trials for alopecia areata 2
Special Populations
Children with Alopecia
- Refer to pediatric clinical psychologist, educational psychologist, or social worker if there is significant change in the child's behavior (withdrawn, low self-esteem, failing at school) 1
Stress-Related Hair Loss (Telogen Effluvium)
- Reassurance is therapeutic, explaining that spontaneous remission is expected once stress is controlled, with regrowth typically beginning within 3-6 months 4
- Address the bidirectional nature of hair loss and anxiety, as the psychological impact of hair loss itself may require independent treatment 4
Common Pitfalls to Avoid
- Do not order extensive autoimmune panels in straightforward alopecia areata cases, as investigations are unnecessary when diagnosis is clinically evident 1, 2
- Do not fail to warn patients about the possibility of relapse following or during initially successful treatment, as some find this difficult to cope with 1
- Do not overlook the psychological component, as the distress from hair loss often perpetuates the anxiety-hair loss cycle 4
- Do not pursue treatment in patients with poor prognostic factors (longstanding extensive disease) when wigs would provide better quality of life 1
