The basic answer to the usual question – why is hair coloring done is given as follows –
To give back gray hair its previous color;
To modify the hair color to a shade considered as more fashionable or desirable;
To get back the original hair color after discoloration by chemicals (e.g. tints, relaxers, sun bleaching).
Hair coloring products are mainly classified based on how long the color remains in the hair. The four usual classifications are
Demi-permanent (sometimes called ‘deposit only’)
Temporary Hair Color
Temporary hair color is comes in different forms such as rinses, shampoos, gels, sprays, foams. This hair color happens to be typically brighter than the semi-permanent and permanent hair colors. This type of color is mainly used to color hair for special events and mostly the shades are unusual as it is apt for occasions, parties and Halloween. The pigment molecules present in temporary hair color is always large and cannot go deep in the cuticle surface. On the other hand, the color particles stays adsorbed (closely attached) to the hair shaft and can be with ease removed with shampooing it for once.
Nonetheless, even temporary hair color can stay for long if the user’s hair is too dry or damaged, letting the pigments migrate to the interior of the hair shaft. The penetration and color strength of temporary hair color can be improved by bleaching prior to application.
Semipermanent Hair Color
Semi-permanent hair color contains smaller molecules than the temporary hair colors and therefore partial penetration in the hair shaft is possible. For this reason, the color can stand repeated washing, specifically 4-5 times of shampooing. Semi-permanent color have no developer, peroxide or ammonia and thus they are safe for damaged or weak hair. The other components could be toxic compound P-Phenylenediamine or alike ingredients.
The resultant color of each hair strand will depend on its original color and porosity, so there will be very little variations in the shade all over the head. The result will give a more natural look than the solid, allover color of a permanent dye. However, it also means that gray or white hairs will not dye to the same shade as the rest of the hair. If there are only a few gray/white hairs, the effect will usually be enough for them to blend in, but as the gray spreads, there will come a point where it cannot be disguised. In this case, the move to permanent color can at times get delayed with the use of the semi-permanent as a base and adding highlights. Remember that semi-permanent will never be able to lighten up the hair.
Demi Permanent Hair Color
Demi-permanent hair color is nothing but permanent hair color combined with low volume developer that blows off ammonia from the permanent tube, leaving behind only the color molecules which penetrate the hair shaft. This type of hair color is more effective to cover gray hair than the previous category surely is less effective than permanent colors. The advantages of this color are galore when weighed with semi permanent color.
All ‘permanent’ haircolor products and lighteners in the market comprise a developer (oxidizing agent) and an alkalizing agent ammonia. When the tint containing the alkalizing component is combined with the developer (usually hydrogen peroxide), the peroxide becomes alkaline and diffuses through the hair fiber, entering the cortex, where the melanin is located. Lightening occurs when the peroxide breaks up the melanin and replaces it with new color. The ammonia opens up the cuticle only to allow the color pigments penetrate deep into the hair shaft.
Permanent color doesn’t wash out, although it may fade off with time. New hair regrowth will obviously be in the hair’s natural color, meaning that regular monthly or six-weekly coloring will be required for as long as the hair color is maintained. The only way to get rid of permanent color is to undergo a stripping process (which is not possible with all colors and can damage the hair) or color it back to its natural color (which can be difficult if the color change has been extreme).
Have you thought about it? Whether to use a single process color, or go for the double process color? The former is definitely bound to be less time consuming and also save few bucks, making a lesser hole in the pocket.
Single Process means that a new color or toner is applied all over to create a new base color. The hair is lifted and deposited in one easy step. It’s the most common out of the two, and it’s wonderful for covering grays and adding shininess to dull hair. Plus, it’s also great for the home hair colorist.
Double Process is typically used when lightening hair by more than two shades. First the hair is bleached to remove natural or colored hair pigments, and then pigment is added into the hair to create the desired shade. To avoid hair drama, leave this one to the pros.
Hair Color Retouch
Once you have tinted your hair and achieved the glorious hair color of your choice, there will come a time when most of you will have to face a tedious chore”Â¦the retouch. After four to eight weeks of living with the new vibrant color, you probably have gotten used to and maybe even begun to think of it as your own natural shade. Then there it is, down at your scalp, the tell tale sign of darker hair or duller or gray hair threatening to tell the world that this new persona of yours is not the original. Now you have to entertain the idea of doing it all again.
Since the first one half to one inch of your hair is un-tinted and has been previously tinted from that point on out to the ends you must not treat it as though it were all the same. If you apply the hair color to the entire length of hair, it can result in uneven color tone and dry, damaged hair. Instead, it is best to perform what we call the “retouch” This is not as easy as the original application but it is rewarding when it comes to the condition of your hair and the evenness of hair color. Following these instructions will save you time and trouble.
Gather everything you will need.
An old shirt for you to wear.
An old sheet or some old towels to spread out on the floor. This is important since one stray drop of hair color can give you a lasting reminder of this session.
Plastic or rubber gloves. These usually come in your packaged hair color kit.
Clips; four to six of either the long “duck bill” kind or the “jaws” variety. You can find these in your local variety store.
Kitchen timer or a clock that is easy to keep an eye on.
Proceed in the following manner:
Divide your hair into four or five sections. If possible control all the hair in each section with a clip, with no ends dangling.
Put on your gloves and mix your color in the applicator bottle provided in the hair color kit.
Take down one section of your hair. Using the tip of the applicator bottle divide off a thin slice of hair at the top of the section and place a thin ribbon of hair color along the new growth area. With a gloved finger or thumb “moosh” the color into the hair being careful to spread it only on the new growth. Clip this slice of hair up out of the way and divide off another slice.
Continue in this way throughout each section of hair until you have successfully applied hair color to all of the new growth area.
Follow the manufacturers instructions in timing. If you have resistant or hard to color hair, -sometimes, gray hair is resistantcovering it loosely with a plastic bag while processing is helpful.
For faded ends
Add a small amount of shampoo or conditioner to your left-over color.
Wait until the last five minutes of the processing time and apply this mixture to the rest of your hair. This is to refresh the color and is not a necessary step.
When the timing is complete, shampoo and follow up with a good quality conditioner to preserve the health of your hair.
Some people are born with naturally shiny hair while others need a little help. For those who need help, a hair glossing treatment can work wonders. It gives your hair luxurious sheen. Salons may charge $50 or more for a glossing treatment. For approximately $12, you can buy enough supplies to perform three glossing treatments at home
Hair highlighting is different from hair coloring. Hair coloring defines coloring of the entire hair and highlighting defines coloring only a few strands of hair. Hair highlights are often restricted to bright shades with a metallic tint.
Hair highlighting can be classified into :
Foil highlighting – foil is used to separate and wrap strands of hair so the color is not mixed with other strands.
Hair painting – a brush or comb is used to paint a color.
Chunking – way of coloring different sizes chunks of hair.
Low-lighting – method of applying lighter shades.
One can do hair highlights at home or under guidance of a professional stylist at a salon. Celebrities often become role models. One can by a hair
highlighting kit which also helps in producing hot highlight.
Highlighting is a variation or modification of ages old hairstyles. The only difference is in taking extra care. Earlier people used natural hair highlights but now the trend has shifted to the use of chemicals for highlighting. These chemicals sometimes tend to damage hair, on prolonged exposure to sun light. It may become difficult to regain the original texture of hair.
