  • A rinse will wash out either at the 1st shampoo after you have put it in your hair or in several weeks. Dye won't wash out and will have to grow out. Your roots will come in your natural hair color but the rest of your hair will be the color you dyed it until you have it cut off.
  • 1) "Consumers considering changing their hair color have a choice of four main types of coloring agents to use. What distinguishes them is how long they last and how they color hair. Coal-tar ingredients are found in some products in all categories except gradual dyes. Temporary hair colors are applied in the form of rinses, gels, mousses, and sprays. These products merely sit on the surface of the hair and are usually washed out with the next shampoo although some may last two to three washings. If the hair gets wet, during a rainstorm for example, the color can run from the hair onto clothing or the face. Semi-permanent dyes penetrate into the hair shaft and do not rinse off with water like temporary colorings. They do wash out of the hair, however, after about five to ten shampoos. Semi-permanent dyes come in liquid, gel or aerosol foam forms. After applying the product to the hair the user waits 20 to 40 minutes before working it in like a shampoo and then thoroughly rinsing with water. Permanent dyes require a bit more work, pay-off is hair color that lasts until the new hair--"roots"--grows in. Because permanent dyes contain hydrogen peroxide, they cover gray hair more effectively and can be used to lighten hair color, unlike other dyes. To apply permanent dyes the user mixes together a hydrogen peroxide liquid with another liquid, works the mixture into the hair, and after about a half an hour rinses the dye out with water. Permanent dyes not only penetrate deeply into the hair shaft, but get locked within it due to a series of chemical reactions that occur while the dye is applied. Consequently, permanent dyes can't be washed out with shampoo. A fourth type of hair dye is known as a gradual or progressive dye. This dye, in the form of a rinse, slightly darkens hair by binding to compounds on the hair's surface. Gradual dyes are usually applied daily until a dark enough shade is achieved, after which it may be used less often to maintain the color. Unlike temporary dyes, gradual dyes don't wash off readily or run when the hair gets wet. Compounds suspected of causing cancer are found in temporary, semi-permanent and permanent dyes."

"Can someone please explain to me what a color rinse is and how I can get one/ do one myself? Are these products that I can buy or should I go to a salon? Is it as damaging as permanent hair dye? Has anyone had any experiences with henna? I've heard that it takes a long time, is temporary and gets all over the bathtub... I'm interested in hair color or highlights but have heard so many horror stories from hair dye (never done it before) that I really don't think I'm going to take this option no matter what. I'd still love some insight on it though." "I think that there are pros and cons of all the methods you've mentioned. For color (permanent) the pros are you get a nice permanent color that looks great and can provide shine. The cons are that your hair will be dry dry dry and you must moisturize, moisturize, moisturize! You must be more vigilant in your hair care efforts with PERMANENT COLOR. If your interested in something that's not too damaging you should try a DEMI permanent color which is stronger than a rinse but not as harsh as a permanent color. It lasts for about 24-28 shampoos and often contains low levels of ammonia or peroxide. These are good because you can play around with different colors and won't have severe drying or breakage. As with permanent color you still have to be vigilant about your hair care. Semi permanent are good because they wash out in 8-12 washes, are non drying (most of the time) and won't interfere with your chemical process (relaxer). There is no commitment with this so once it fades then you can move on to other color options or not do it again. Henna is a complex bag of tricks! I did Henna and it turned out okay for me. But some complain of dryness and it can make it difficult if you decide to go the permanent route, henna can interfere. Most henna on the market is not pure so they can alter your effects, I've heard that this site http://Mehandi.com offers some of the best quality henna."

Hair coloring can be permanent or temporary and the lasting effects are determined, in part, by the texture of the individual's hair. The use of chemical lighteners, such as bleach, is one way hair is lightened or "highlighted". This type of hair coloring is always permanent because it involves the removal of natural pigment, which never returns. Semi-permanent hair color can darken or change the tonal value of the hair, but cannot lighten the hair and can usually be completely washed away after several shampoos. Semi-permanent hair color is only a deposit of hair color. This hair color is used to darken natural hair color. "Rinses" are a form of temporary hair color that are usually applied to hair during a shampoo. Their effects usually only last until the hair is shampooed or rinsed. Permanent hair color is probably the most-utilized because of its ability to affect the hair in level (lightness or darkness) as well as tone, but it comes with a unique set of potential problems, such as the need to frequently re-apply, unwanted fading and hot roots."

  • A rinse is less drastic and more temporary.
