There are numerous reasons for a person to opt for various hair color ideas. Whatever the reason is, the need for a root touch up is absolutely necessary for a person with colored hair. Hair grows at the rate of 1.27 cm per month, which causes a definitive line on the strands that separates the colored part of the hair from the newly grown part. In other words, the growth divides the hair color near the roots. To avoid this partition, you need to color the roots. This process is called a touch up which you can perform using three types of dye: liquid, powder, or cream. Types of Touch Ups The liquid dye has a thin consistency and you need to combine it with a color developer like hydrogen peroxide. You can apply the liquid color with the help of a bottle dropper and then rub it on the roots. The powder dye can just be dabbed on the roots. This is an easy procedure, and it also mops away the excessive oil and moisture from the scalp, just like dry shampoo. While the cream dye comes in a tube, you still need to combine it with a developer and then apply it with a thin brush. If the color has faded throughout the strands, then you can increase the area of application of the dye. This is the best way to maintain the color between two visits to the salon. Best Products There are many types of products available for different types of hair and various colors. Once you select the color, you can choose the type of touch up product you want. Powder and pen products are mainly used as an instant way to conceal the color difference. These products don't require combinations like the cream and liquid dyes, and hence are preferred by most consumers. The color only stays there until you wash your tresses. After that, you need to reapply it. However, there are some brands of touch up sticks that are waterproof and provide protection from a quick jump in the pool or a sudden drizzle. This is the reason why these are popular products for quick and easy results. Gray Roots Gray hair is one of the prime causes why people color their tresses. Temporary root touch ups prove to be a real savior for those with gray hair. You need to decide whether you want to use the pen, sponge, stick, or brush, and then purchase one. While selecting the dye, always opt for darker hues of your current color. Always purchase the dye after doing a strand test, which is important to avoid the possibility of the wrong color and any kinds of resultant allergies. It is also important for you to use a special shampoo for color treated hair. Once you follow all these important tips, then the application of the dye is quite easy. Procedure Here are some easy steps that you need to follow to apply liquid or cream dye on your roots. Before you start, make sure you wear latex hand gloves and worn-out clothes.

• Get the dye ready as per the instructions on the box. Now, divide your hair into four equal sections, and pin each one with a clip. Most importantly, apply a layer of petroleum jelly along your hairline in order to avoid the color from spreading on your forehead.
• Now, unclip the front sections of hair and apply the dye mixture on the roots. Make sure you don't massage the color on the scalp. Apply the color again by flipping your hair, re-clip your hair, and repeat the process with the rest of your hair.
• Once the color dries, comb it from the roots to tips so that it can spread throughout your mane. If you find any gray spots, then color them again. Repeat the procedure until all the roots are covered in dye.
