I find fudge the best purple shampoo I've ever used! It works so well. My hair tends to go quite brassy, so this is perfect every couple of weeks. Sometimes i leave it in for 5+ minutes and it gets a purply-silvery tone which I love!
I always make sure to give my hair a good condition afterwards otherwise it can feel a little drying.
I love this stuff for my blonde hair, it always looks so fresh and vibrant after washing. Regrowth looks less and you only need to use a little bit which means it lasts for ages and ages!!
Tips: Be careful not to use every wash or if your hair is reeally light as it could change pigment or colour of your hair to a purple/grey tone
