Hi Todd,
Yes, it works on hair. Usually when we do men’s hair, we leave a tiny bit untouched just around the hairline at the face and it can look so natural.

Hi Chrissan,
I asked them and they said if you go to the Faq section of their website, It answers all their questions.

Thanks Paulette, I appreciate your information so much. I’d love to hear how it does the next time you use it.
Love, Nancy

Well, the Hairprint did even out my color so that I am brown all over. It appears to have varying shades of brown to make it look more natural. It looks so much better than the brassy look I had. The few scattered gray hairs are still gray, though. I will use Hairprint again and maybe the gray strands will turn brown as my hair becomes healthier.

Hi Mary, Here is a response from the Hairprint company:

“The concentrations of hydrogen peroxide we use are between 1% and 1.5%, a fraction of what one gets in drugstore peroxide. In conventional hair dyes, peroxide is used to break open the hair, and can be up to a 12-15% concentration. We do not use it to open the hair follicle (which is very damaging) but rather to oxidize the mucuna pruriens extract. When applied to your hair, the peroxide is virtually gone. The green reaction that some people have mentioned applies to the high concentration of hydrogen peroxide that occurs with bleaching products reacting with Ferrous gluconate/iron. We have always recommended a transition process be used for people that dye their hair blond or brown using conventional dyes.
Indigo/henna and Hairprint are perfectly safe to use together. No green effect has ever been reported or occurred in any of our research or our growing customer experience. I myself used henna and know that the process is lengthly, messy and extremely time consuming. If you are using henna/indigo to get a medium brown which is your natural color you can use our hair chart found on our products page to determine which kit would work best for you. I included the link for your convenience. It sounds like the 3100 or the brown option might suit your needs. The color chart is located on this page as well. http://www.myhairprint.com/products/women-european-hispanic-and-asian-hair.

All the best

Mary, I asked them.

“We do not know. The peroxide is mixed with the formula before it goes on the hair, but we cannot assure of anything here.”

Here is the email for Hairprint support: support@myhairprint.zendesk.com

Hi Stasia, It is called permanent if it doesn’t wash out of the hair.
So, it will stay in the hair that is treated.

This product is made of food grade ingredients. it is non-toxic. This isn’t a hair dye like the other products on the market. If you contact support@myhairprint.zendesk.com they can answer any questions you have about this product.

Hi Eugene,
Yes, it is safe. It is all food grade, non toxic ingredients.
Let me know if you have any other questions!

Hi Nicky, It is for anyone, male or female. I just happen to use it on my male friend, who had a lot of grey hair.
They have it for browns and black hair color so far, but are working on ones for lighter blonde color hair now too.

Yes, it is non-toxic and works naturally on your own personal hair shaft – original color.
