If you're planning to become pregnant and have SjÃ¶gren's syndrome, ask your GP to test for certain antibodies that may be present in SjÃ¶gren's syndrome and are known to cause a temporary lupus rash in newborn babies. In very rare cases, the antibodies can also cause heart defects in babies.
Users of semi-permanent or temporary hair color can expect their color to last for about 6 weeks. Color fades with shampooing and exposure to air.
Though some people prefer to wait as long as two to three months between reapplying hair dye, a period of six to eight weeks is sufficient enough to reapply hair dye. Permanent colouring dyes contain a greater quantity of Ammonia and Peroxide where as temporary hair dyes contain either none or negligible quantities.
