There are two types of hair colourants: the permanent and the semi-permanent. If you have more than 25% grey hair, you may go in for a permanent colour to cover it. If you want your hair lightened, permanent colour is generally a ‘must’. Permanent hair colour grows out before it washes out. But, if you just want to experiment and try out something different, you could try a temporary rinse which adds highlights to darker shades. A temporary rinse lasts until your next shampoo. For a longer lasting colour, your stylist may use a semi-permanent hair colour, which lasts through six shampoos, at least. If the hair is fragile or not in good shape, a semi-permanent or an in-between colour generally will be gentler than permanent hair colour. The in-between type of colour is between the permanent and the semi-permanent and does not contain any ammonia. It lasts almost as long as the permanent colour i.e. through 25-30 shampoos. The most stressfulprocess on the hair is a double process in which hair is bleached first and then coloured.
