I'm a natural redhead, fuck whatever your brother says! People love redheads, and after I dyed my hair black, my hair has been darker even after the dye faded out!
remember dying you hair severely damages it. it has to break do9wn the protine you hair is made of, so the dye can take instead try out new colors with those level 1 kinds,, it is just a color rinse.. but making y9u hair lighter will require that you strip the protien so be thoughtful if you go that far it will e a long time till you can get back the natural texture
If yuo MUST< use only the level one,, the kind that does not bleach/burn your hair. You can see what it lookes like NOT to be ginger, but when iwashes out yuor hair will be healty NO MATTER WHAT a hair professional will tell you.. If use the stron kind? Your hair will be fried afterward.
The g8inger gene, is really different, odd effect, an entirely different kind of pigment tha all other people. A bit more acid body chemistry. Strong resistance to alkaloids ( novacaine etc) EVERYone want to date ya LOL
