lemon highlights guestion!!?

Question

so yesterday i tried highlighting my hair with lemons and it worked pretty good but i want to finish today and i have a few questions.
1. how do you know when its done, does you hair like feel different or something?

2. how long do i have to stay out until its done. if i stay in the sun longer will it turn lighter?

3. does it fade?

Answer 1

the longer you are in the sun, the lighter you will get
won't fade
take a mirror outside with you so you can look and see when it is time to go in
