Quasi permanent hair color is gentle on the hair structure, but gets lighter with each hair wash. This type of color keeps the hair structure soft.
It might make your hair dry and will cause split ends
There is permanent hair color and semi-permanent hair color. _____________ Demi permanent and temporary are also known as non permanent hair color.
Yes, you can apply permanent hair color on top of semi-permanent hair color. Make sure that you do a deep conditioning treatment or hair masque before and after you color your hair.
Yes, it is OK and safe to apply semi permanent hair color on top of semi permanent hair color. The end result may be a little darker though.
A semi permanent colour is a colour that lasts 6-8 weeks. It lies just under the cuticle of the hair and this is why it washes out. (It doesn't enter into the hair or affect the internal structure of the hair).
I am a licensed Redken Certified Haircolorist. You should NEVER overlap permanent hair color. Permanent color has higher levels of ammonia which will dry and damage the hair. New hair (virgin hair) that has never been colored can be colored with permanent hair dye in order to cover gray or lighten. If ends are faded, a demi-permanent hair color should be used to refresh, brighten and add shine.
Can the permanent color hair spray easily wash away during washing
Of course you can. Semi permanent dye simply adds color to your hair. A permanent will actually cause your natural color to change. But remember this... color doesn't lift color. Therefore if your semi permanent hair color is darker than the permanent color you are going for---- it isn't going to work. You need to use a color remover before hand. And color removers are REALLY damaging to hair.

Yes, demi permanent hair color can be applied over any type of color. It will refresh the original color very nicely.
Demi permanent is better for covering gray hair than semi permanent so make sure you read the package carefully. Also demi permanent color doesn't actually lighten hair only darkens it. If you want it lighter the best option is permanent hair color. It does cover gray hair though, but permanent covers grey hair even better.
