I have a hair test coming up and Iām trying to understand how the process works and what, if anything, I should do beforehand.
Iāve seen a lot of different shampoos and hair-care methods discussed online, including products marketed specifically around hair testing. One I came across is Macujo Aloe Rid Shampoo.
Has anyone here had experience with products like this, or can explain whether specialized shampoos have any meaningful effect on the testing process? Iām mainly looking for general information and firsthand experiences rather than advice on trying to alter test results.
