How to remove my natural hair pigment?

Well,I'm an asian junior high school student and my natural hair color is black but a little bit brown since I'm a chinese.

Question is I wanna get a red (or at least more red than now) or even brown hair naturally.Because I can't dye my hair because of school rules.So is there anything I could do so I could get a red hair and weaken my black hair pigment and replace it with red pigment instead?

Thank you so much for reading my question.Please help me as much as you could do.I'll appreciate it no matter what answer you might give.Thank you.

Use a temporary mousse dye ( like coler pulse from Loreal Paris) and spread it very thinly throughout your hair and just sort of let it tint your hair and then rinse out. Viola! A whole new tone! It won't look like you've dyed it unless you leave it in too long. Just let it sort of 'sting' your hair by letting it sit half the time and using one-fourths of the product recommended. I know how you feel, my parents wouldn't let me dye my hair but they let me do temporary. But the method I just wrote for you is just to give your hair a little tiny bit of coler, kind of like really natural blush on skin.

Nope the only way to do this is with color even the technique you are talking about would be using hair dye. Sorry!

You should embrace your lovely color but if you cant the only way to weaken it is to buy this product called stripper it will take out pigment then you have to dye it red like the next day but since that is against school rules I dont see much you can do. My aunt had red hair and wanted blonde so she used the stripper to take away the red and it was really ugly till she dyed it. I hope this helps answer your question.
