It would make your hair a different color than what it was supposed to be.
-----------------------------
Is you're using a darker color, eventually the color will "shut itself off" and just quit working, so keeping it on the hair longer won't be harmful. Using a lighter color is a different story. As long as the lighter color doesn't dry out, it will keep working and may cause damage or breakage from over-lightening.
No it wont, Its ruins your hair, Making it harder to straighten
personally, i think it does. however all dyed differ. and as long as you dont leave it in for too long, i really dont see the problem in doing so.
No their not. Dr's are supposed to keep that confidential.
it usually says on the back of the pot, 30 minutes but i have found that the longer you leave it in the darker it is and the longer it stays in for. personally i keep my hair dye in for 2
Depends on the color you want. The dye should have come with instructions to indicate what shade it will come out dependent on how long you had it on. It usually gets darker the longer it is in.
depending on your pigment ... A suntan will leave your skin darker while a sunburn will leave you skin red ... if your very pigmented (black) your skin in all cases will get darker ...
leave it
for whatever time you want the longer you leave it on the curlier , for medium/long hair sleeping with them would give you the best results
No... That is strange.
because of rotation of earth
yes they do get darker. example when you breast feed the child will suck your niple and will cut off cirulation and there it will turn darker. You could also tight up a rubber band in the nipple and leave it their for a few minutes. Thnx

The softer the pencil is the thicker and darker a line it will leave
It takes about 20-30 minutes to actually put the color on your hair and then you have to leave it on your hair for 25 to 45 minutes, depending on the color. It should say on the box. If you leave it in longer than you are supposed to you hair will be more brittle and may break off.
