a strand test is carried out after applying colour to a hair. You remove the colour of a strand of the hair to check if you have the desired result (colour)
A test is cutting a bit of hair off that you wouldn't notice on the hair and putting it on a bit of foil and put the colour that you would choose for it on the foil. Then after that leave it for full developing time. It's very important to do this because if your client wants to dye their hair a different colour but you want to make sure it doesn't go a different colour you feel that you should do a strand test as well then do it before you give the client a colour service.
