Coloring your hair at home is tempting: it saves time, saves money and lets you try new shades on your own schedule. But hair color is a chemical service, and doing it well takes preparation. Wella Professionals colors, such as the Koleston Perfect Deep Browns 7/7 Medium Blonde Brown, are professional products, so it is important to understand what you are working with.
This beginner's guide walks through the basics so you can make a safe and informed decision.
Professional Color Is Different
Professional hair colors are designed for trained colorists and are typically more powerful and more precise than supermarket boxes. Koleston Perfect is known for intense pigments, brilliant shine and full grey coverage. That is great when used correctly, but it also means mistakes can be more noticeable.
If you are new to coloring, consider having a professional do your first color and learning from the experience.
Step One: Do an Allergy Test
This is the most important step, and it should never be skipped. Wella's product information reminds users that although the risk of developing a new allergy is reduced, a risk of allergic reaction that can be severe remains, and that an Allergy Alert Test should be performed 48 hours before each coloration. Follow the safety instructions on the pack strictly.
Step Two: Choose Your Shade Carefully
Shade numbers describe the depth and tone. In a code like 7/7, the first number shows how light or dark the shade is, and the number after the slash shows the tone. Choose a shade close to your natural color for your first attempt, since going a couple of levels darker is easier than going lighter.
Step Three: Understand the Developer
Permanent color is mixed with a developer, which activates the color and determines how much lift it delivers. Wella offers products like the Welloxon Perfect 6% 20 Vol Cream Developer, designed to work with Wella's permanent hair colors and lighteners. Always follow the mixing ratio and instructions from the manufacturer.
- Do an allergy test 48 hours before coloring
- Choose a shade close to your natural color first
- Use the recommended developer and follow mixing instructions
- Protect your skin and clothing before you start
Step Four: Protect Your Skin
Color stains the skin and can irritate it. Apply a barrier cream along the hairline, ears and neck, and wear gloves. The Wella Color Service Skin Protection Cream is designed for exactly this purpose during color, lightening or perm services.
Step Five: Apply Evenly
Section your hair into four parts, apply color to the roots first if you are covering regrowth, and then work through the lengths as directed. Use enough product to saturate each section evenly, and follow the timing instructions closely. Set a timer so you do not overprocess.
Step Six: Rinse and Aftercare
Rinse with lukewarm water until it runs clear, then follow with a color-safe shampoo and conditioner. A dedicated color-care shampoo such as the ColorMotion+ Color Protection Shampoo helps lock in color and maintain smoothness. Wait a couple of days before your next wash where possible.
When to See a Professional
Some jobs are best left to a colorist: going from dark to blonde, correcting a color mistake, covering previous box dye, or coloring hair that is already damaged. A professional can assess your hair, plan the process and protect its condition.
Hair color has a long history and a well-understood chemistry. According to general information on hair coloring, the process works by changing or depositing pigment in the hair shaft, and permanent methods use developers to open the hair and allow color to develop, which is why careful preparation and testing matter.
