I dyed my hair today with a strawberry blonde color hoping my natural color would make it a little darker but it seems to have done nothing! Last night I used color oops to take the previous dye out n there were lighter patches from previous dying. None of my hair came out lighter and it is also not red. I don't know what I can do, I want a light brown with reddish tint. My hair is naturally dark brown. Help please!

Try using a different types of hair dye, if that doesn't work then it might be because different people's hair respond to certain hair dyes and the colour in the hair dyes differently.
Stay Safe :)
