How to Dye Your Hair Purple or Dark Blue
I went blue-haired for the first time in 2004 using the Fudge Paintbox line of temporary hair colors.
Unfortunately, although I was aiming for a deep navy blue/purple, I ended up with more of an aquamarine color, which washed out within a month.
I wasn't happy, but wasn't ready to give up.
I switched colors, combined tubes, tested various shampoos and conditioners, and refined the coloring process until I had a long lasting dark purple/blue, which faded gradually over 3 months into interesting stripes of color.
Before following these instructions, make sure you test your skin for bad reactions to both the bleach solution.
Also, do a skin test for at least 24 hours to each color that you want to use, individually, and mixed together.
Fudge Paintbox Color
How much dye will I need?
I needed to use two full tubes of Fudge Paintbox color for my hair when it was a little past shoulder length.
Now that my hair is quickly approaching my waist, I would need at least 3, if not 4 tubes.
For short hair, I used just under one total tube of color.
Buy a little more than you think you will need - it's better than running out without completely dying your hair!
The two things you must have for this process are the bowl (for mixing the bleach, and then the dye), and a wide applicator brush. The comb with the thin tail is fantastic for sectioning hair, and the clips necessary if you have long hair! A great set for a fantastic price!
- powder bleach for hair
- creme peroxide for hair (creme developer)
- Fudge Paintbox color tubes - enough for your hair length
- plastic bowl - large enough to mix and apply an appropriate amount of bleach
- applicator brush
- old plastic hair comb
- vaseline (petroleum jelly)
- plastic gloves - at least 2 sets
- plastic wrap (saran wrap, Clingwrap)
- plastic disposable shower cap
- old clothes - they will be splattered with bleach and color
- old towels to put on the floor - you will drip bleach and color
- old face cloth
- old towels to use when sleeping
Preparation - setting up
Make sure your hair is clean and dry before starting.
Clear away anything unnecessary - avoid unintended splatter stains of bleach and hair dye!
Block access to the bathroom - don't let pets or children inside during this process!
Step 1 - Bleaching
Bleaching allows the hair color to deeply penetrate the hair shaft. Without bleaching, the hair shaft will only allow in a small amount of color, which is easily washed away.
I recommend that you bleach your hair, even when you are re-coloring. It allows for an even and deep color penetration.
I used a 6% creme peroxide developer (20 Volume) with powder bleach, mixed to the instructions on the back of the tubs. I have light brown/dark blonde hair, and with this solution, my hair did not go white (a golden yellow blonde - not the nicest of colors). But it did allow for an even dark blue color to cover my hair.
- Put the old towels on the floor of the bathroom, and wear your old clothes.
- Open a window and turn the exhaust fan on, if you have one. Bleaching produces a lot of fumes.
- Protect your hands with plastic gloves.
- Carefully mix the recommended amount of powder bleach for hair and creme peroxide for hair together in the bowl with the applicator brush. Mix until it becomes a smooth, thick paste.
- Apply the paste gradually and evenly with the applicator brush, starting from the roots of your hair, at your scalp.
Note: If you apply the paste to the ends first, they will knot together, and you will be unable to reach the hair roots!
- When finished, pile long hair on top of scalp. Don't let it sit on your neck/shoulders!
- Leave the bleach paste on for the recommended time - specified in the instructions for the bleach powder/creme peroxide. You may experience some burning and itching at the scalp. If it becomes painful, wash the bleach out immediately.
- While waiting for the bleach to lighten, clean everything thoroughly.
- Keep wearing the plastic gloves, and follow the instructions for rinsing the bleach out. I find it easier to thoroughly rinse my hair in the shower, rather than bending over a laundry sink.
Results: Now your hair should be a lighter, even color.
Mine was quite yellow-blonde - very strange!
Step 2 - Applying the hair dye
This is where I depart from the recommended instructions on the Fudge Paintbox tubes.
Important: You should test to make sure you won't react to the dye over a long time (leave it on your skin for at least a day before washing it off).
Keep the towels on the floor, keep wearing your old clothes, the window open, and pets/kids locked out of the bathroom. The last thing I'd want is blue/purple paw-prints throughout the house!
- Prepare the plastic wrap - you'll need it when you finish applying the dye.
- Smear Vaseline (petroleum jelly) around the edges of your hairline, and all over your ears, taking care not to get any in your hair. Skin will be dyed along with hair!
- Wear plastic gloves to protect your hands.
- Mix the colors together thoroughly in the plastic bowl with the application brush.
- You may find it useful to section your hair with small butterfly clips, so you can apply the dye evenly.
- Evenly 'paint' the dye onto sections of the hair with the applicator brush, starting from the roots at the nape of the neck, moving slowly to cover the whole hair.
Tip: I found that an application pattern starting at the nape of the neck and roots of the hair, moving to the top of the head/face and then to the ends of the hair strands minimizes mess, and has the best chance of even application.
- When your hair is thoroughly coated, massage the 'paint' thoroughly through the hair. It ensures that there is an even coat, from the scalp to the ends.
- Pile your hair on top of your head, trying to make it as solid and non-slipping as possible.
- Remove your gloves, and wrap long pieces of the plastic wrap around your hair, until it is solid and covered.
- Clean the dye from your skin (especially around your ears) using soap and water, and the old face cloth. Don't forget your neck and shoulders, and your hands/arms above the gloves.
Also clean any dye splatters that have touched porcelain immediately - they can stain very quickly!
- Put the plastic shower cap on - it helps keep the plastic wrap in place.
- Clean everything thoroughly. Dispose of paint tubes and plastic gloves securely.
Step 3 - Setting the dye
The recommended time to leave the dye on is under an hour. I found that the resulting color was washed out within a month.
The best result for me, was when I left the dye in overnight - the heat from my plastic-wrapped head while I slept allowed the dye to penetrate very deeply, resulting in long-lasting color.
Disclaimer: I take no responsibility for any adverse reactions - you must test the safety of this on yourself before choosing not to follow the directions for Fudge Paintbox dyes.
- Use old sheets and blankets.
- Use old towels and cover your pillow with multiple layers.
- Protect your doona cover and blankets by wrapping a large old towel over the edge closest to your pillow.
- The next morning, remove the shower cap and plastic wrap from your hair.
- Wash the color out in the shower with a lot of of water, while wearing plastic gloves.
- Shampoo once or twice, and scrub with soap on an old face cloth at any dye patches on the skin to lighten them.
- Use a large amount of color-care conditioner - this helps to 'set' the color and close the hair shaft.
- Dispose of the plastic wrap, shower cap and plastic gloves so that kids and pets can't get to them.
- Wash all towels and clothing that you have used during this bleach/dye process.
For the first week, it is a good idea to sleep on pillow covers or a towel that you don't mind dying blue/purple. Color will come from your scalp and hair while you sleep.
Paint your nails a dark color - scratching your head will result in dark blue/purple nails!
Use old towels when drying your hair after washing for the first few weeks, or until the color stops noticeably dying the towels.
Making the color last
Use a top quality color-care shampoo and conditioner, and wash hair every few days, not every day.
I trialled at least 5 brands before settling on Loreal's Elvive Color Protect line - it kept the color dark for the longest time of all the brands I tried.
With twice-weekly washes, the color gradually faded over 3 months, before I re-colored.
Your hair's condition will deteriorate with each subsequent bleach.
To keep your hair in better condition for a longer time:
- Use a top quality conditioner.
- Use a good color-protecting hair masque treatment.
- Avoid using hot oil treatments - some can strip color.
- Avoid blow-drying your hair.
- Use little if any hair styling product like hair spray, gel or wax.
