I've been dying my hair with henna for several years now and this is what works for me to get the brightest red.
I've experimented with other colors and combinations of henna and indigo, but I keep coming back to the red, I find it so stunning, especially in the warmer months.
Shower and shampoo. No conditioner. I usually do this a day in advance.
Mix your dye.
Add a few tablespoons of lemon juice for a brighter red.
Add hot water until the consistency is nice.
Let the mix sit for half an hour (or so) so the color can activate.
Prepare your work space.
Put a towel on the floor. Wear junky clothing, especially a top that you can get over your head very easily. Get plastic gloves for your hands. Get a mirror to view the back of your head. Maybe invest in a little hair dye brush for more precise application.
Apply the henna.
I like to start at the top and just form each section into a bun on top of my head. When my hair was shorter, I had to use clips to keep the hair up and out of the way. I've tried starting from the bottom and working up and starting from the top working down and I find starting at the top is a little easier for me personally. Then you also don't have to worry too much about running out of product toward the end, it's not a big deal if it's the underside of your hair.
Wrap hair in plastic wrap for a brighter red. Put a beanie on top for even more warmth and brightness. And wait. Try to keep it on for at least two hours. The longer, the better.
Time to rinse.
Use conditioner to rinse. I don't use shampoo for about 2 days after I henna. Rinse with conditioner many times. When you think you've rinsed for the last time, do it once more just in case. This time I rinsed three times with a cleansing conditioner.
Blow dry your hair so you can immediately see the results.
I have no patience. I need to see how things turned out immediately, so I almost always blow dry right afterwards. :)
The color lasts amazingly well. It will stay bright until you're ready to do your roots again. There's no need to touch up the overall color, the only time I know it needs to be done is because my roots are getting out of hand. And when I am ready to do my roots, I will focus on them, but still drag the color through the rest of my hair too just for a little refresher.
I typically dye every 3 months, but this time around it's been a lot longer, about 6 months! Ever since the birth of my first son in May 2016, I've stretched the time between colorings more than I did before the kiddos.
I really hope this was helpful for you and you found some good tips. I've been dying my hair with henna for several years now and this is what works for me.
