Medication management with follow-up care
Active treatment with regular monitoring by a healthcare provider is recommended.
Comprehensive Immunological Assessment
Serial measurements of lymphocyte subsets, mitogen responses, and antibody production guide therapeutic decisions. Regular monitoring catches progression of immune dysfunction.
Additional treatment options
Psychosocial Support for Alopecia
Counseling and support groups address the emotional impact of congenital alopecia. Cognitive-behavioral approaches help manage body image concerns and social anxiety.
psychologicalProtective Head Care
Wigs, scarves, and protective headwear prevent scalp sunburn and heat loss. Gentle scalp care reduces infection risk while maintaining comfort.
