78-year-old woman with severely itchy psoriasis, bald from scratching her scalp and pulling out her hair found relief from the itch within five minutes of applying a 30% mannitol cream. After using the cream twice daily for 5 weeks, her scalp psoriasis had subsided and her hair had regrown. The effect of this cream on her lower back psoriasis is documented with photographs. The psoriasis recurred when the cream was no longer available.
