Dye dreads?

Hi, Well i would like to dye the tips of some of my dreads to make them looklighter. I was wondering if i can do it now. My dreads are 4 moths and i have dark hair.I dont know if they will damage a lot or what, so that's why i haven't done yet haha. So can i dye them or it's better if i wait a little more?...and i'd like to dye 5 maybe 6 of my dreads not all of them. Thanks

From experience, they should be fine. I've dyed about 5 or 6 of my dreads as well and they turned out great.

Thanks Daydreamer , I think i'll try
