I have been havng a reaction to the temporary coloring I put in my
hair.  Head breaks out with what seems like dandruff in a day or two
and it itches some and won't go away!  I want to keep coloring my
hair.  It's dark blonde.  Can anyone help??   LR

what kind of product are you using?

If you have to mix two substances together then apply it to your hair,
you are NOT using a "temporary" color.  There is a reactive process
happening in the bottle and to your hair.  The only truly temporary
product that is not reactive and easily available is Roux Color Rinse.
 It is available at beauty supply stores, drug stores, and some
supermarkets.  A color mousse is also available.  You will not get
total coverage of grey hair but it will blend it in.  ALL color
products should be patch tested before use.  Instructios are on the
bottle.  I hope this helped.  justme9
