Permanent Hair Color Is A Permanent Solution To Premature Greying Since a permanent hair color doesn’t fade away gradually, it becomes an optimum choice for covering grey hair, changing hair color, and lightening or darkening hair. But the new growth of hair will look different from the colored hair. And if you don’t take any corrective measures, the difference in your natural hair tone and colored hair will be significant.

But there is little to worry about as you can deposit color over lightened hair and correct the color that has gone off-tone with demi-permanent professional hair color. It will even enhance the natural hair color and blend grey. A demi-permanent color is a low-ammonia formula and it is mixed with a low-volume developer. It can add more shine to your hair but it can’t cover grey or even lighten the hair color. It fades gradually and lasts up to 24 shampoos.

Also, you can refresh faded hair color and blend grey with a semi-permanent hair color. It will even add shine and restore the luster of dull hair. But it won’t lighten your hair or cover grey. It is only used for refreshing the hair color. Since it doesn’t need ammonia, it is found in many shampoos and conditioners. You can check the ingredients of a hair care product to know whether it contains hair color before buying.
