Is it bad to leave a hair mask on for longer than it says to?

Lololol

but in reality ,i wouldn’t leave it in for too long because it may build up oil and make your hair greasy feeling .unless your hair is unbarebly dry than a few extra minutes wont hurt your hair.

I dont think so, as long as you wash it all out after, and as long as its not going to cause irritation to your scalp.

it depends on your hair type.. what type is it?

I would not really know, but I would say it would be better if you don’t, just because it sais on the instructions to leave it on for a certain time for a reason. I guess that it would not complitly harm you, but I would say follow the intrstructions, just to be on the safe side.

It depends on the hair mask. Generally no, hairmasks are made to help your hair and shouldn’t cause any damage. I would think that the reason they tell you to keep it on a certain time is that after that time, the chemicals don’t have the same effect anymore, so you’d probably just be wasting your time keeping it on longer.

It depends what kind of mask it is. If it is a protein mask, then yes- leaving it on will feed to much protein to your hair. In extreme cases causing it to go hard like uncooked noodles and snap off at the roots. If it is a moisture treatment, it should be fine but it’s best to stick to the MIs when using any hair products. I’ve seen so many people thinking they know better than the box, then I have to ‘fix’ their hair.
