It is NOT a dye. Day by day Grecian Formula gradually replaces gray with your natural looking color. You can stop at anytime and leave a little gray, or keep going. Different hair colors are the result of different amounts of melanin, nature's coloring process, Darker hair simply has more melanin than lighter hair. As melanin production decreases with age hair turns gray. Grecian has the ability to replace lost melanin with a similar-acting pigment You can replace the right amount of lost color by applying Grecian for a few days, up to two/three weeks.

hair cells at the root produce pigment that gives hair it's color. as we age a key enzyme is no longer produced so that the cells can not produce pigment. this product restores the ability of that enzyme. thus one nice advantage of grecian is never having gray roots like with dyes as hair grows out

​Different hair colors are the result of different amounts of melanin​--dark brown or black hair simply has more melanin than light brown or blond hair. In time, as melanin decreases, gray hair appears. ​​Grecian works with the hair's natural chemistry to produce a similar-acting pigment where the melanin used to be.​​Grecian works for any color hair because you control the process so you determine when you regain your right color.http://grecian-formula.com/faq.php

It can be used on eyebrows, if works for me; it will not change the color of your hair and skin/scalp. I noticed no color change on me.

My hair color was almost dark brown (between dark blonde and dark brown), and I've been using for 5 months and I'm almost blonde now.. Sometimes it looks a little bit like red, but depends on the light. It will work, but I'm a little concerned about what color would turn, since the product says that dark hair will turn a little bit red and not blonde.

Nop. Its not a for hair coloring. It is for enhancing color and shine. It makes your hair more soft shining and straight. No friz. Leave it on for 20 min. Then wash normaly.

This is a real product. It is a conditioner that softens hair and helps maintain color. I use this on my hair that is highlighted blonde to maintain color between visits to my hairdresser.

This is not a permanent color: it is plant based and washes out in a few shampoos. I alternate this with permanent hair color, since I find these products to make my hair very healthy.

I didn't ask when I ordered it but, I did change the hair color with a thin coat of matte acrylic. It is still fine after a year or so. Use a small taklon brush to apply the acrylic.

It does not work on any color hair. Not even bleached or grey hair. Try a different brand.

Not that I'm aware of. It's kind of more like a toner. It says on the bottle it can be used on all kinds of hair colors. I have brown hair with highlights. It's just kind of revives the highlights but doesn't affect the rest of my hair.

Hi Tessa...I have never tried so I am not positive...I know they can take the heat of a curling iron so if I were you I would do the "strand test" that they suggest on all boxes of haircolor, to see if it turns the color you're wanting. ( They have usually already been dyed already -depending on the color you bought- since they come from China or India) So definately do the "strand test".

I don't think it works on dark hair without lightening it first. Usually light colors won't change dark hair. When I used it, I lightened my hair with color oops, meant for stripping out artificial hair color, and it worked well for me after that. Hope I helped in some way, that's just my experience!

This product is a color lightener and it give a nice outcome for those who have light colored hair ( blond and brown hair) dark colored hair may become reddish but I really do not recommend using this product in your case ...

It does not leave any cast of color on your hair ( my hair is dark- so I completely know what you are referring too) this product however is not a dry shampoo... It's a texturizing spray. It will make your hair feel ' no so clean' and give it some texture and grit.. Similar to dry shampoo. I love it! It's one of my Holy grail products!

It doesn't matter the color of the hair. It just enrich the hair. My mom and wife use it when they dye their hair with hana and it works very well...

It can be mix with hair dye, hair bleach. It does not affect the hair dye or bleach in any way. All this product does is to remove redness from the hair when u lighten it several shades from its original hair shade. It doesn't make the hair look like it was a wig from the ompa Lompa factory.
