Thanks for this!
I always find information about the chemical processes of dyeing very interesting.
I'm interested in making a lawsone extract from henna leaves so that I can keep it in a bottle to
1) avoid the mess of the henna paste
2) be able to more easily control the intensity of color I get from the dye (can dilute, etc. with a solution)
3) make it portable-- my little sis, who loves henna, is going to college in the fall, and I'd love to make this for her so she can bring it with and easily use it in dorm bathrooms instead of the paste
4) pre-extracted means no wait for the proteins in the henna to break down and release dye for on-demand coloring
5) be able to add it to things like conditioner for gradual coloring or maintenance of color
6) As an organic chemist, it just seems like a fun experiment
What are your thoughts on something like this? Lawsone looks like it would be pretty water soluble, so maybe its just a matter of making the henna, with the lemon juice or whatever acid, and draining it from the mixture with the use of some water. Then maybe I can concentrate the solution by just letting some of the water evaporate or some gentle heating that won't degrade the dye molecule.
On a side note, once I made henna but was out of lemon juice, so I used vinegar as the acid instead. My hair came out ORANGE as opposed to the strawberry blonde I normally get. Given that vinegar is a weaker acid than lemon juice, this doesn't make sense chemically. Think it was just a fluke and I used too much acid that time, or do you think something else was at play? Love to hear your thoughts.
Keep up the good work!!
Chantal-Do NOT use henna tat has PPD. PPD is in regular hair dye. It is the chemical that usually cause allergic reactions. Google henna for hair, mehendi.com, or butters n bars. These sights have high quality henna. I use Light Mountain. It can also be googled. I buy it at Whole Foods. It has premixed colors which are combinations of henna, cassia, and indigo to produce differing colors. All natural. All pure. Finally natural products are hit or miss. Chemical will give a more consistent result but higher chance for problems like allergic reactions.( Which can develop even after years of using the same hair color). Hope this info helps.
I have a couple questions regarding Henna, it's quality and effectiveness.
Before I found your website, I bought a few boxes of Henna at a local Indian place. Most didn't cover the gray. One of them from Achal Impex INC makes a black Henna - Kali Mehandi, which is maybe coming from you. On the box there is a sticker with the listed ingredients: Henna, PPD, citric acid.
- What is PPD, and what it stands for? Is it an abreviated name for p-Phenylenediamine?
- I have chemically dark brown dyed hairs and I applied the
black henna. Does that mean that my hairs will never get lighter?

I want my hair to be the deep bright red the final result was all the time. Will it be that color?
Thank you so much for this tutorial! I really enjoyed it. I was going to dye my hair with henna powder but I wanted to get a little more information on it. I have dark brown hair already and was wondering what shade it would turn into? Would it still turn the vibrant red that you have or would it be darker?
