I only waited two days since I needed to color my hair, but that did not affect the keratin at all. The treatment lasted two months on my hair, but since I have the product at home and I am a hairdresser, I do it on myself almost every month or when I feel that my hair is getting to volumous, which I don't like, so it depends on how you like your hair to look like. The new growth is what makes the hair look different because the rest stays straight for a long time if you use the right shampoo and don't use a lot of harsh products on it.

I forgot to say that I do the keratin treatment first and then color my hair because the clarifying shampoo takes some of the color off the hair.

I changed my color hair then I used this keratin. Unfortunately it doesn't last long just one month.

If you have dyed your hair black in the last four months I wouldn't recommend using this. If it has been over four months then sweet it will be amazing. You will however need to do your hair two times in order to achieve a full and even color. Red does however wash out quickly! ! It goes into an orange color within about 8 weeks. You will only want to wash your hair once or twice a week in very cold water with clear (sulfate free) shampoo as well as conditioner. Red hair should always be dry before you fall asleep because it will rub off on EVERYTHING. I had my hair this bright red color for about 7 months and it costed me around 300.

I color my hair a dark brown so when it just starts to grow out it will cover it somewhat and usually give me a couple more weeks till I have to color again. But if your looking for it just to cover gray I don't think you would be happy.

I'm not to sure, but I have a very light brownish red hair and it has a little orange tint to my hair after dying it, so if you have dark hair just follow the time that it's says for your hair color, I think for light brunette I think was 45-65mins and dark brunette was 60-90 mins. I've never personally have had dark hair so I honestly don't know

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.

It last about two weeks for me. I have short hair and get it cut avout every ten days. So I have to color it more than required.

This product is really good! It will stain anything. It catches on better on bleached hair of coarse. If your hair is not almost confused as a light brown colour then you should be okay. It should get on pretty well and last long enough! Maybe a little more than two month. Just make sure to apply it correctly! Good luck&#128077;

24 hours after you use the product are the manufactures featured benefits however I wait 48 hour. You can always use a flat iron anytime after any Keritan procedure. Hot iron seals keratin to the hair follical

I would bleach first, so your color is even. The splat bleach works very quickly so keep an eye on it. My hair was a light brown and it only took 25 min. for it to come up.

You'll wanna wait a couple weeks. Coloring shortly after can cause an excess about of damage you don't need and could alter the straightening system.

You might want to wait a couple of weeks to see if the color fades just a bit, otherwise, depending on the condition of your hair, you can recolor any time. I usually color my hair at 5/6 weeks.

As long as you follow up with a conditioner you should be fine. If you have colored ends I would do something with keratin and moisture to keep the integrity of the hair. :) (I am a licensed cosmetologist fyi)

I don't know. Sorry! I have blonde highlights in very dark brown hair and it made it difficult to even comb through. I can comb my hair no problem now and it's shinier. But I don't know about keratin at all.

If done correctly and you use the proper products to maintain the health of your hair the process lasts forever. Your new growth will reveal the before and after and you will see a big difference.

It's a semi permanent hair dye. It's more like a hair stain meaning it will wash out a little every time you shampoo your hair. With that being said it still last a very long time depending on how your hair was before you dyed it. If you bleach your hair first it will last much longer and be more vibrant. I usually dye my hair about every 2 months when the roots are visible.

I have the same color hair and used this product. I recommend doing a strand test first. Gather up some of your hair from a hairbrush (it can be a big wad of hair), mix a bit of the henna as per instructions, and put your test hair in the henna. Keep track of the time and check it every 10 minutes (wash the hair off). It will give you a good idea of what you're up against. I left mine on for 20 minutes and the color was definitely red but not flaming red. Everyone's hair is different - so definitely do the strand test first.I documented my henna experience on my blog - complete with pictures. Sedonavortexter is the blog name - search for that word and you'll find it. It's in the 2012 entries.Good luck! I have the same color hair and used this product.
