How to Use Rainbow Henna for Dyeing Your Hair

A peek inside this post: Are you curious about Rainbow Henna hair dye? We’ll go over it all in this post! Rainbow henna ingredients and henna vs. chemical hair dye will be covered, as well as answering the question, “How long does henna last in your hair?”. I’ll share my tried and true rainbow henna hair dye recipe and a video tutorial on how to use rainbow henna for dyeing your hair, too!

After years of trying natural hair dye recipes with no success, I was thrilled when I came across Rainbow Henna Hair Dye while shopping with my sister-in-law in a health food store.

I picked up that little white canister and thought, “What do I have to lose?”

I was on a mission to find something without chemicals that would help me color my hair. Not just to add color, but more so to hide the gray. I started getting grays in my 30s and now at 37 I have a pretty good amount.

I tried so many things before… tea, coffee, honey, lemon juice, herbs and spices. I followed the directions but never saw the desired results. There may have been a slight tint after some of these hair dye remedies but nothing stuck. I was squinting to see the change and the gray hair was as bold as ever. 

When I found the Rainbow Henna Hair Dye, I was skeptical but hopeful! And a little scared, honestly.

If you’re feeling a little apprehensive about using henna hair dye, too– don’t worry! I’ll walk you through the ins and outs! I’m sure you have a few questions right off the bat, so let’s start there...

Rainbow Henna Ingredients: What Exactly IS Henna?

Henna is plant leaves that are crushed up into powder. Henna has been used for ages to dye skin, hair, fabric, fingernails, and more. You may have heard of henna tattoos.

It comes from the earth and when combined with liquid, it makes a paste that can be used to change the color of things.

Rainbow henna literally just consists of plant powders. That’s it! No dyes, chemicals, or any other yucky stuff!

How Long Does Henna Last in Your Hair?

The one downside that I have with henna is that the dye job only lasts about a month before I want to dye it again.

I only wash my hair about 2 times a week and henna holds well for me. After about a month, I see the gray popping out again and I give it a refresh.

I don’t mind dyeing my hair about once a month because I enjoy the product, the price, and the safety of using plant-based dye. When you check out the reasons I love rainbow henna below, you’ll understand!

Thoughts on Henna vs. Chemical Hair Dye

I much prefer henna over chemical hair dye (in an at-home box or salon experience).

I love Rainbow Henna hair dye because:

  • At under $10, it’s extremely cost-efficient. I can use one container about 3 times (all in all, it costs less than $4 to dye my hair)
  • It’s completely natural: no chemicals like most hair dye
  • Flexibility of dyeing my hair in my home and getting other things done while it sits
  • I do not feel the need to pass out from the smell like I do with commercial hair dye products

Please note: If you are dyeing your hair for the first time and have a lot of hair to cover, you may want to use more than I use. My hair is pretty thin and medium in length, and it only costs me about $4 to dye my hair each month! My sister-in-law uses the entire jar for her long, beautiful, dark hair and it works so well for her!

My Rainbow Henna Hair Dye Recipe & Helpful Tips

It was a couple years ago, but I remember it like it was yesterday. I mixed up my hair dye (which you can see in my HOW TO VIDEO). It smelled like a farm and it looked like animal waste. It was new to me and I added too much coffee so it was runny, too. (Yes, I mix it with coffee!)

Ingredients used to dye your hair with Rainbow Henna hair dye

I started painting that paste on my hair and dripping dye around the bathroom. It wasn’t pretty.

I had a lot to learn, but I will share my hard-earned knowledge with you!

After a couple hours, I went to wash it out in the shower. It was drippy and messy and I wasn’t sure I was going to do this ever again. 

Then, I took my towel off and I think I heard a few angels singing. The gray was gone! I combed my hair, dried it, and they were still gone! In fact, it looked like all the grays were highlighted a softer color. Like I did it on purpose! 

From that morning on, I knew I was a Henna girl.

Ingredients You Will Need:

  • Rainbow Henna in color (or colors) of your choice. I’m currently using both mahogany and light brown mixed together!
  • cup of hot coffee
  • splash of cider vinegar

I don’t have exact measurements, I judge how much to use based on consistency. You want your henna mixture to have the consistency of a thick paste.

How much henna you use will depend on how long and thick your hair is. I can use about 1/3 of the powder in my rainbow henna container, whereas my long-locked sister-in-law uses the whole jar every time. The amount of powder you use will determine how much liquid coffee you should mix it with.

It’s also helpful to have:

  • a paint brush
  • bowl and spoon
  • plastic grocery bag
  • towel wrap for your hair
  • old t-shirt
  • paper towels

How to Use Rainbow Henna for Dyeing Your Hair

Watch this helpful video, which breaks down the following steps!

1| Mix your ingredients together.

You want the consistency to be that of a thick paste.

2| Let your mixture sit for about 10 minutes.

You can use this time to get your bathroom (or wherever you’ll be dyeing your hair) ready. Make sure to put paper towels, a plastic grocery bag, and a towel wrap for your hair in there. And don’t forget to throw on an old t-shirt!

3| Use a paint brush to paint the henna paste onto your hair.

Focus on the gray roots, and work in sections. You can work more of the henna mixture throughout the rest of your hair once the roots have been well covered.

4| Wrap up your hair.

Gather your hair and put a plastic grocery bag over it to prevent dripping and staining. Then put a towel or wrap over the bag.

How Long Do You Leave Henna on Your Hair?

I leave the henna on for a couple hours. I use that time to catch up on laundry, mopping floors, meal prep, or sometimes take the time to read!

I love being able to get other things done as I let the henna do its magic!

After a few hours, you can wash your hair thoroughly in the sink or shower. Make sure you have a cup with you to help rinse the color out of the tub, to prevent staining. (I have not had any issues with the henna being difficult to rinse.)

Wash and condition your hair as normal, and be amazed!
