Could you tell me a little more?
What liver function test exactly had been 75, then 55, and now 100? There are a number of liver function tests.
What cholesterol drug were you taking and why did you stop?
Why do you tink hair dye would affect LFTs?
In some people statins such as Lipitor can cause the muscle cramps you experienced, and also an increase in AST and ALT. The liver function tests usually return to normal within weeks of stopping the medication.
There are also a lot of other things that can cause abnormal liver function tests. Among them are hepatitis B and C, alcohol or drug use (such as Tylenol), fatty liver (very common), muscle injury, and a number of others. The hair dye couldn't have caused the increase in AST and ALT. I'm sure your doctor will be drawing more blood samples to determine exactly what is the cause in your case.
Meanwhile, you should avoid alcohol and Tylenol (acetaminophen). If the cause is found to be fatty liver, then losing weight if you are overweight, and following a healthy diet with lots of fruits and vegetables, lean protein, fiber from whole grains and plenty of liquids will help, as will moderate exercise such as brisk walking 30 minutes a day.
The levels of AST you experienced are not highly elevated and it sounds like your primary care provider is doing everything exactly right. So you can stop worrying about your hair color being the culprit, and enjoy being whatever color you like.
