Hair colour is a dye or pigment used to change the color of hair. The process can be temporary, where the color fades out after several washes, or permanent (also known as “permanent wave”, “perm” and “hair perm”), which refers to when the pigmentation remains in place until it grows out naturally.

Hair Colour: Frequently asked questions

What types of Hair Colour are there and what determines a good product?

There are two types of hair colour, permanent and semi-permanent. Semi-permanent is a temporary dye that washes out after about 6 shampoos. Permanent dyes last for up to 12 weeks (depending on the brand) but will gradually fade over time until it’s gone completely from your hair. It’s important to note that these colours can be damaging if not applied correctly so always follow instructions carefully.

A good hair colour is one that looks natural and blends in with your own hair. It should be long lasting, easy to apply, wash out easily without damaging the hair and have a great shine.

Who should use a Hair Colour?

Anyone who wants to cover grey hair or add colour back into their hair.

Based on what criteria should you buy a Hair Colour?

The best way to select a Hair Colour is to find out as much information about it as possible (such as reading reviews). You can also compare prices from sellers that I have found, which are often cheaper than buying direct from the manufacturer. Another good practice is to look at an unbiased review of any product before you buy it online.

The first thing you need to look out for is the colour of the hair. It should be a natural looking shade that blends well with your own hair color and skin tone. You also have to check if there are any chemicals present in it as these can cause damage to your scalp, especially when used on a regular basis. A good quality Hair Colour will not contain harmful ingredients like ammonia or peroxide which may lead to dryness, itching or irritation of the scalp and even some serious health issues such as cancer. So make sure you read all labels carefully before buying one.

What are the advantages and disadvantages of a Hair Colour?


Hair colour is a permanent hair dye that gives your hair the desired shade. It can be used to cover grey hairs, or add highlights and lowlights for an all-over new look. The best part about using this product is that it does not damage your natural tresses like chemical dyes do. You will also save time as you don’t have to wait for long hours before washing off the color from your scalp.


The disadvantages of a Hair Colour are that it is temporary and can be washed out. It also does not provide any protection from the sun, so if you have light coloured hair or blonde highlights then I would recommend using a sunscreen on your scalp when in direct sunlight as this will help to prevent premature greying of the hair.
