Good ! Love the color - be aware, it's MESSY to apply, and stinky. But darn cheap and effective.
but MESSY to apply (put it on in the shower, and maybe with someone to help you), with a certain smell, but since it is a natural product you can use it guilt-free and during pregnancy also I would think. I added juice of one lemon to the mix and let it sit for 1 hour before application, then I slept on it and rinsed the next day. The color immediately after dye is a very fiery radiant red, that looks good and is not monotone (probably because of uneven application by myself, but that's ok - it has dimension) and my friend said it looked professional.
However, the color faded quite a bit within 2 weeks of nearly daily showering to a red-orange tint over my med-dark brown hair, but this tint is staying pretty much permanently now. However, I got this mostly to cover all my new white hairs that have appeared just in the last year at age 35, and I had NEVER dyed my hair before this in my life. This product does a good job of covering the white hairs; they are still tinted orange (but it looks good against the rest of my hair), and they gradually lighten over time. I tried the light red but couldn't tell any difference between that and this so I will just use this color. I apply it every 1 or 2 months, and the cost is so low this is no problem, but it depends on how fast the stain on my white hairs fade and if I notice a lot of white roots. The color, since it isn't opaque, allows the underlying lighter and darker parts of my hair to show, so it isn't one-dimensional. The color is very flattering; I love it and many people have commented favorably on it, and I will continue to use this.
