Here's How to Fix It
If you've ever dyed your hair with natural hair color and noticed it turning more blue, green, or turquoise than you expected, don't worry, you're not alone. This occurrence is quite common and completely normal. The reason behind this phenomenon is the presence of indigo pigments found in many dark shades of natural hair dyes. These pigments can give your hair an unexpected blueish or greenish hue, which might differ from your initial expectations.
Could you wait a few days?
Henna oxidizes over 2 to 7 days, darkening and deepening in color. What looked like blue or green immediately after washing out the dye may calm down to dark brown or soft black after oxidizing.
Indeed, for achieving darker hair colors like black or dark brown using natural dyes, you can mix the orange pigment from henna with the blue pigment from indigo. The combination of these two pigments creates a balanced shade that results in dark brown or black hair color.
Henna + Indigo
It takes time for indigo to turn blue
Indigo dye starts out green or turquoise and slowly turns dark blue. Remember that indigo-blue takes about 48-72 hours to develop fully, so be patient after hair dyeing. If you want to speed up the development process, you wet your hair and let it dry naturally about three times, which can help the blue color develop more quickly. This will speed up the transition from green hair to dark hair.
If your hair's blue color is still strong
Some add coffee and teas to keep their hair from turning greenish-blue, but going over the hair with henna is the best way to remove the greenish-blue to a darker color. Indigo is alkaline and reacts with henna, which is acidic to turn indigo-dyed hair from brown or red to black.
Turquoise color after dyeing hair
If your hair appears turquoise instead of dark blue immediately after dyeing it with a natural hair color, as shown in this photo, it's possible that the dyeing process might not have been completed entirely. In some cases, using henna can result in the color appearing too strong, leading to an orange hue. To address this, I would suggest waiting for a few days to allow the color to settle and potentially darken. Alternatively, you may consider re-dyeing your hair with the same natural hair color to achieve your desired shade. Patience and a second attempt can often yield better results.
How to use the henna leaf powder in your blue hair
Henna is a natural plant-based dye that imparts an orange-red color to the hair. Mix the henna powder into a paste with water and apply it to the hair. To slight tone, the blue down, and leave the henna on for a short time (15 or 30 minutes). The longer you leave the indigo on, the darker and less blue your hair will be.
