should i dye my hair again after it has been dyed 4 times and relaxed 3 times???

Why color it again? I assume since you are writing from Malaysia that you are a beautiful Asian woman with dark hair.
Wear your hair it's natural color.
Asian ladies look very good as brunettes.

The fact dyeing and using other chemicals on the hair will damage it, I agree with. The more you dye it, the worse condition it'll get into. If your hair is short, dyeing it often won't affect it as much, because the damaged parts get cut off more frequently, but if it's long you have to be extra-careful. Long hair can get really fried and frizzy if you put chemicals on it too much, and putting treatments on it will only make it look less damaged temporarily. The reality is, if it's long and you use chemicals on it a lot, it'll just get really messed up and there's nothing that can really repair it, just you'll have to cut the damaged parts off.
As to whether Asian hair looks good dyed or not, it really depends on the person. I've seen plenty of Asians who look gorgeous in red, brown, or even blonde hair. But there are also some who look really strange in it, too. *shrugs* As long as you try on wigs first to see which category you fall in, it's not really a big problem, though.

if you keep drying your hair you self you will do alot of more problems to your hair you sholud go to a hairdresses to have it done there can tell you what to do .but i would not do it yourself as i did do the same and dry it my self.
