Are you thinking about coloring your hair but are confused between a full hair color and a root touch-up? A lot of people struggle to understand the difference between the two and which option is best for their hair.
Simply put, a full hair color is chosen when you want to change your entire hair color or desire a fresh and new look. A root touch-up, on the other hand, is meant solely to cover newly grown roots or grey hair. It keeps your existing hair color looking fresh and eliminates the need to color your entire head repeatedly.

What Is Full Hair Colour?
Full hair colour means applying colour to the entire length of your hair, from the roots to the ends. It allows you to completely transform your look or simply refresh and even out your current hair colour.
This hair colour option is great for those who are colouring their hair for the first time, want to change their natural hair colour, or need to cover grey hair throughout their hair. This hair coloring process ensures a uniform colour across your entire head, and gives you a new look.
What Is a Root Touch-Up?
Root touch-up refers to coloring hair only at the hair roots, which makes sure that there is no patchy look. This procedure does not include coloring the whole hair strands. After coloring your hair, your natural hair or gray hair will start growing after some days.
These roots are visible due to natural hair growth. The visibility of these roots affects the overall look of the hair color as the hair color looks uneven. This procedure helps cover the visible roots of the hair.
