Signs and symptoms of this condition include lardge nodules and cysts as well as smaller follicular papules. Hair loss occurs over the affected region and permanent scarring and bald patches appear. Treatment options for dissecting cellulitis of the scalp includes steroids and antibiotics but the condition does not typically improve even after treatment.
