Hi! I just did my strand test for my first henna. But I didn't really see much of a change in the color of my hair. Could you help me pinpoint what I might have done?

I used BAQ yemeni henna and indigo. I mixed the henna with a splash of lemon juice and let it sit for 12 hours. Then I tested it and it turned my skin orange. Then I mixed and added the indigo. I put it on the strand test and put it in my pocket for 4 hours.

After washing, the blonde is a really really light red and the brown looks the exact same shade. Will it change colors with more applications. Or do some hairs just not uptake the dye? Any tips on helping hair take in more dye?

Thank you!
Toni
