How to Section Your Hair Properly

As a stylist, it is important to divide the hair into four sections prior to lightening or coloring. Start by parting the hair down the center from front to back, and then across the side of the head from ear to ear. This gives you four sections of hair that are easy to work with and keeps other areas out of the way.

Begin parting your hair straight down the middle from the front to back. Comb and brush hair in order to remove any knots or tangles. Comb the hair forward from the middle part to the top of the ear and then twirl it over your finger. Clip it in place with a bobby pin. Move the marker to the lower section that is directly underneath and to the other side of where it is currently located, then move it in a line-like pattern until it reaches the back and repeats. Finish by combing the section with your fingers to smooth and blend the hair.P

How To Dye Sections?

Begin in the front section of your choice (left or right) and apply the color you are using according to the package directions (or according to the process you are performing) in that section and move to the next forward section. The front sections of the hair are the most visible and need to be treated first to ensure that they don’t prematurely shrink. We work with these sections first because they will have the longest time for processing.

End in the front section of your choice (left or right) and apply the color you are using according to the package directions (or according to the process you are performing) in that section and move to the back sections. The back sections of the hair are generally treated last because they will have less time for processing. Additionally, we often tend to use lighter colors for the back sections because they will blend in better.

Should I Wash My Hair Clean Before Dyeing?

Yes, you should shampoo your hair clean before dyeing. It is a widespread belief that dirty hair grabs color faster when dyeing it. This is actually a myth and it has been scientifically proven that you should wash your hair before coloring it as the dye will have a better chance of getting properly applied Is it better to have greasy or clean hair before dying?

As it turns out, most hair dyes are actually designed to work better on hair that hasn’t been freshly washed. The reason for this is because color has a tendency to fade in the presence of water.

Manufacturers of professional hair dyes, such as L’Oreal Paris, give some recommendations on washing the hair before coloring:

Do not skip your cleansing routine altogether in the days leading up to your dye job. Feel free to wash your hair a day or two before your dye session, using the L’Oréal Paris Sulfate-Free Simply Clean Shampoo.

However, it is also important to avoid getting your hair dyed if there are excessive chemical residues in the strands which can lead to more serious problems such as scalp irritation and dryness.
