I want to lighten my hair abit but want to avoid actual highlights because i'm pregnant, and I am scared they will turn out zebra like. I read abit about using chamomoile flowers, lemon juice, hemp etc. but does it actually work? My hair is brunette, with some natural blonder bits, goldy bits, coppery bits etc. and has lightened in the past just from the sun, but that was when I was out in it every day, all day. TIA
