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.
Permanent color uses a developer (usually 10, 20, or 30 volume) to change the color fo your hair. This color is, as the name suggests, permanent. It will not wash out. Some people find that their hair will not hold permanent red hair color molecules. Usually this is caused by hair damage, but it could also be natural porosity issues. Permanent hair color is supposed to be called âhair colorâ, not âhair dyeâ. I donât know when it became the standard term, but a lot of salon professionals get really upset about it, so itâs best to use the correct term. Semi-Permanent. One of the terms you hear most when referring to crazy colors is âsemi-permanentâ.
