Iam having head heaviness right now.. i had my hair dye last friday and was told not to wash it for three days.. yesrterday was the 3rd day and when ?

Headache: May or may not be related: Here is some general information on headaches. For specific advice and diagnosis please see a doctor licensed in your area. https://patient.info/health/migraine-leaflet

Headache: I don't think that the heaviness in the head is related to the hair dye this week. You may be dehydrated. Drink plenty of water 2 to 4 oz every hour on the avg (at least 2 liters/day). Take Tylenol or motrin. Good luck
