    Default Red raj henna query

    Hi all, I'm new here! I just had a question for regarding Red Raj henna. Does leaving the henna on overnight give you a more vibrant red rather than leaving it on for a few hours? Many thanks. Vicky xx

    Not really From the time you mix up henna and it dye releases, it hits a peak dye saturation and then the dye starts to gradually demise over time. This means that you get far more dye potency in the first 4 hours of having henna on you head than you get during hours 8-12. So while you do get more dye overall, there is for sure a point of diminishing returns for how long you leave it on.

    Howdy, Vicky--the amount of time that it takes henna to release its dye varies depending on a lot of factors, including how fresh the henna is and what you mix it with. There is an easy way to tell, though. Take note of the color when you first mix up the henna. Then check it every once in a while by taking a spatula, butter knife, or similar, and "turning over" a little bit of the top layer of the paste. At first, the paste will be the same color all the way through. Once the dye is releasing, it will start to have a different color on the surface of the mixture than inside (since the top part is starting to oxidize). Typically it will be a darker, slightly browner color on the top and remain the original color inside. But if you have mixed everything together thoroughly, the dye will release in the entire mixture at the same time. So as soon as you notice that color change between the surface and the interior, it is ready to apply to your hair!
