I've been dying my hair blonde now for like forever, however its starting to get quite dry on the ends and look a little brassy. Does anyone know any home remedies or anything to bring some life back to my hair and make it look healthy again?

I find that when I trim my dead ends every two months my hair stays healthy.

Yep a trim helps lots. Also using deep conditioning treatments weekly or as often as you can. Once you've applied the conditioner, pop on a plastic cap or even a shower cap and leave on for 20-30 minutes. The heat from the scalp will help the conditioner penetrate into the hair. For the brassiness, have you tried a violet toner?

Thank you both... a violet toner? Not sure what that is but I will look into it

Definitely increase the moisture that you put in your hair... and this is done by doing weekly deep conditioning treatments (as PunkChic has suggested).
