e/Blue rinse

Information
has gloss	eng: A blue rinse is a dilute hair dye used to reduce the yellowed (or translucent, showing scalp colour) appearance of greying hair on older women. The ability to see blue decreases with age, so an older woman perceives her uncolored hair to have a yellow-tinge, and the blue rinse brings the color back to a perceived normal color in their eyes. The blue rinse supposedly makes yellow-white hair appear blue-white, but an inexpertly applied blue rinse will leave a distinctly unnatural tinge behind.
