How long does color last after applying it? Do you have to use it each time you shampoo or cowash?

it lasts until your hair grows out. The color does not fade. I love this product. And it's so easy to use. Colors in 7-8 minutes tops!!! does not stain your skin as long as you massage it wearing gloves while your are working it in.

A few days. But it will dry out your hair. If your hair is dry is takes a while for it to color. If it's wet not so much. I won't buy it again.

I've gone platinum and between bleaches and toners, I use this to keep the white nice and bright. Once a week does the trick. I leave it in for a few minutes while I soap up. It must be followed up by a moisturizing conditioner, because leaving any shampoo in will dry the scalp. If I leave it in too long, my hair does take on more of a purple hue, but it's rather pretty when it does that.

It covers my gray strands beautifully, they look like a lighter shade of auburn and come out looking like highlights. The very best part, other than making your hair feel healthy, it that it doesn't wash out like the peroxide colorings. Just remember to super condition your hair afterward. The color of your hair will also become more vibrant each day, for about a week after coloring your hair. It is work, but I will never go back to the chemical alternative...I also get compliments all the time

Since this a natural coloring agent, I wouldn't think there would be any reason why you couldn't reapply in a day or two after coloring. I've been using this for years because I am allergic to regular hair color and some tips I use are: I apply heat to my plastic bag with my dryer every 15 min. or so and leave my color on for a good hour. Rinse only, don't shampoo for 24 hours after coloring. Good Luck!

It has not caused the color to fade. I think my color holds up as well with Savannah as any of my other shampoos

It actually stays pretty bright for a while. I added more in, only to the ends of my hair about every 4 weeks. I get a TON of compliments on the brightness of the color. It does fade to a fainter hue but it took a long time. I wash my hair about 3-4 times a week. It never even got close to fading completely out.

My natural color is a medium brown and it lightens my hair a bit with extended use. I've used same product for about 2 years. It will definitely turn any grey you have into a red/auburn color. The directions say to leave it on for an hour, but I leave it on for two (it wont damage your hair because there aren't any harsh chemicals.) Keep in mind that henna oxidizes and takes about 2 days for full color to actually take form. When I rinse it out, it always seems a little brassy to me, but after a day it softens and on the third day color is a very pretty reddish brown. So to answer your question, I would say that it would probably leave a reddish tone on your hair (maybe seen more in the sunlight) and with highlights red colors would become stronger after extended use........ The good news is that it is inexpensive so if it doesn't work, you didn't spend $150 at a salon. And if you don't like it, no worries because it fades after 3 weeks :)

My wife uses this product. The directions are included in the package together with plastic gloves, plastic hair cover and conditioner. Do not shampoo within 8 hours before coloring your hair. Only apply to hair if you have not used any styling products within 24-48 hours before. If hair has been permed or relaxed best to wait at least 7 days before using. If you have any type of henna, metallic dye or color restorer, wait until it has grown out or cut off before using. Apply CoSaMo to dry hair using gloves provided directly from the bottle. No mixing is required. Cover hair with plastic hair covering. Leave on for 20-40 minutes. Rinse hair until the water is clear. Apply conditioner. Wait for 2 minutes and rinse out. That's all it takes to obtain a lovely color.

Yes, I color my hair and use it every time I shampoo. I only shampoo about once a week to preserve my color though.

I posted the review right after I did it, so my hair is still quite purple after washing it a few times. I do realize it is a little less vibrant, but it looks decent. Afterwards, not from this dye, but from experience, it's likely to leave a little bit of a purple/pink hue after it completely washes out, but I'm sure if you use a "squeaky clean" or dandruff shampoo it'll definitely take most of it out. Even then, if there are still problems, there are wash-ins that you can get that will tone down the purple/pink hues.

Depends on how often you wash your hair (I wash every day), the quality of your water (I have unsoftened water), and if you religiously use only the keratin safe shampoo/conditioner (I do). You should not color your hair during this time as well (I don't). Mine lasted 1-2 mos. It's helped my hair from flat-iron burning and split ends, big time. Hair looks great during and after.

I have used this product for years, I always applied to hair after shampooing. I believe what they mean by rinse in shampoo out .. it is temporary color, and will shampoo out. It is not a permanent hair color. It takes the brassy look from blond or brightens gray hair....

I used it on my dash about a month ago, it's black vinyl. The shine still looks the same the day I applied it. It doesn't seem like I will have to use it anytime soon. I'll probably do it once a year if that. I don't see it becoming more dull by not repeatedly being used. Of course, not every dash is exactly the same material/quality but I think it will last a while for me.

If you want it to last you should heat set it and the color will not fade as bad with wash. It says to do that on the label I have.

My hair grows fast, so an application lasts me about 3-4 weeks, much like other hair dyes. If you leave the surya in your hair long enough when applying, it does a very good job of covering gray. I've not had problems with fading so much as my hair growing out. (I use black). Oh! there is a little bit that rubs off on pillowcases and the top of my white blouses, but not much. I try to really rinse well and I wash my hair a couple of times per week.

The product lasts until you wash your hair. I spray only the roots and have not had a problem with it rubbing off. I normally wash my hair every other day, but the few times I went 4 days it stayed on.
