Hair dyes in different colours are available in 3 categories- Temporary, semi-permanent, and permanent.
Persons interested in keeping the colour for only one day can use the dye or coloring item.
Semi-permanent dyes will go away after washing the hair while bathing from 6-10-12 times. Every time of taking bath will result in a portion of the applied dye being removed with the water.
Permanent dye remains with hair for ever. Persons can select their own preference of any type of dye.
Note: it is essential that only special shampoos & conditioners meant for dyes hair to be used and not the normal shampoos/conditioners sold in the shops.
Better avoid shampoos with strong chemicals. Take spa oil massage meant for dyed hair while visiting the parlor.
Do not get into the habit of changing the color of the dye quite often. This will certainly harm the hair! It is best to use dye once in a month. Drink at least 2 liters of water every day! As the chemicals in the dyes can be toxic to the body, drinking sufficient water can help get rid of the same.
