I'm currently doing the henna treatment by Ancient Sunrise, it's a kit with Henna and Indigo, it's the version of Henna for African Hair...I watched a video by MopTopMaven and she recommended adding conditioner to the henna, so I did so along with a diluted lemon juice...so I will report back on what happens when the treatment is complete...I plan on leaving the henna on for a full 24 hours and then utilize the indigo treatment for about 4-6 hours tomorrow...so I report back...but I have to say I did feel that the henna treatment itself elongated my 4B curls...so I will see...
