Natural Ways to Lighten Hair: Safe & Effective Options

Question
So heres my dilemma, When I sit in the sun my hair lightens from a dark-med brown to a lighter brown with blondish bits, however I've just got a part that requires me to go blonde I don't want to pay to get it dyed and am too afraid to home dye, a home remedy that worked would be fantastic. Recently a local store reduced their hair lightener and its very cheap and works too, but it leaves hair lighter and its for light hair, its leaves darker hair a yellowy colour, would I have to dye then? Preferably a home method but also one that will be safe for my hair ;) Thanks so much :D P.S the sun doesnt come about very often I live in Ireland :(

Hi!
Um you could use peroxide (3%), or you camomile tea (boil it for about 15 min.) then put it in a spray bottle and spritz it throughout your hair then lay in a place in your house that tends to be more warm (since the sun doesnt come out often), you could use fresh squeezed lemonade and spritz that in your hair and lay in the same room, thats really everything i can think of.
Oh, and an alternative for a warm temperatured room is to heat up some foil or saran wrap and wrap that around your hair.
