Hair Loss Treatment Options

Treatment for Alopecia Areata

The British Association of Dermatologists recommends intralesional corticosteroid injections as first-line treatment for limited patchy hair loss, with triamcinolone acetonide (5-10 mg/mL) injected into affected areas showing 62% full regrowth rates in patients with fewer than five patches 2
Each injection of 0.05-0.1 mL produces a tuft of hair growth approximately 0.5 cm in diameter, according to the British Journal of Dermatology guidelines 1
For extensive patchy hair loss, contact immunotherapy with diphenylcyclopropenone (DPCP) is recommended, though availability is limited, as suggested by the British Journal of Dermatology 2, 3
Topical corticosteroids have limited evidence for effectiveness but are widely used, as noted by the British Journal of Dermatology 1

Minoxidil may stimulate hair growth after chemotherapy-induced alopecia (CIA) or endocrine therapy-induced alopecia (EIA), according to the Annals of Oncology 4
Scalp cooling is the only method shown to prevent hair loss, with 50-65% of patients developing only grade 1 alopecia when used, as reported by the Annals of Oncology 4

Biotin (2.5 mg daily) and orthosilicic acid (10 mg daily) supplements may be considered but are not generally recommended due to limited evidence, as stated by the Annals of Oncology 4
For severe or long-standing alopecia areata, wigs may be a better option than pursuing treatments with low likelihood of success, according to the British Journal of Dermatology 1, 5
Spontaneous remission occurs in up to 80% of patients with limited patchy alopecia areata of short duration (<1 year), making no treatment a legitimate option in these cases, as noted by the British Journal of Dermatology 2
Treatment expectations should be realistic—complete hair restoration is unlikely, but partial regrowth is achievable for many patients, as suggested by the British Journal of Dermatology 2
