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.
SPMU will eventually fade and as stated it depends on several factors (skin,exposure to weather, ink aplication etc...). All semi-permanent make up will eventually require a top-up; some will need to be applied after 18 months, some will need to be applied 2-3 years after the first application.
