Thought It Was Dandruff... Could Scalp Psoriasis Lead to Alopecia If Left Untreated?

Hair, which Donguibogam describes as the surplus of blood, is also recognized in modern medicine as being directly influenced by nutritional status, hormonal balance, and above all, the immune system. Scalp psoriasis is not simple dandruff or dermatitis, but a chronic autoimmune disease caused by immune system dysfunction. Normally, scalp cells slowly develop and shed over several weeks, but in psoriasis, excessive activation of T cells causes them to proliferate too quickly within just a few days, leading to thick keratin buildup and inflammation. What Donguibogam refers to as blood heat or blood dryness can be linked in modern medicine to a chronic inflammatory response, microcirculatory disturbance, and dehydration. When the blood carries heat and becomes dry, it indicates that the immune system is overly reactive and releasing inflammatory cytokines throughout the body. This inflammatory response impairs capillary function in the scalp, preventing adequate nutrients and oxygen from reaching the hair follicles, which shortens the hair growth cycle and leads to alopecia. Roughly 50% of psoriasis patients develop lesions on the scalp, which are accompanied by intense itching, red patches, and white, scale-like keratin. These symptoms worsen inflammation around the hair follicles. When patients scratch away the flakes, the physical irritation can damage the follicles and increase the risk of permanent alopecia. Moreover, because psoriasis has strong associations with other systemic conditions such as arthritis, metabolic syndrome, and cardiovascular disease, it should not be viewed simply as a scalp issue; overall systemic care is essential. Modern medicine manages psoriasis using topical steroids, vitamin D derivatives, immunosuppressants, and biologic agents. Alongside these treatments, lifestyle adjustments such as stress management, a balanced diet, and adequate sleep play a crucial role in restoring immune balance and preventing flare-ups. Rather than dismissing the condition as mere dandruff, it is important to pay attention to your body's signals and take proactive steps early on.
