Henna Strand Test

[Nita81]

How long are you supposed to do the strand test?

I'll like to know as well.... as I plan to henna in about 2-3 weeks

I've done anywhere from 1-2 hours. From what I've read, if it's going to do anything to your hair it should happen pretty soon after the henna touches the hair.

i left mine on the harvested hair for the same amount of time I planned on leaving it on my whole head - 3 hours.
