What Happens When You Change the Color of Your Hair?

The color of your hair is made by animal pigment pigments scattered like Easter eggs through the cortex of your hair shafts. 2 pigments in your hair provides it its color: eumelanin and phaeomelanin. Eumelanin is the main pigment in darker hair. It offers your hair a spread of shades from red-brown to black. Phaeomelanin is the main pigment in lighter hair colors. It offers hair a light-weight yellow or red color. the precise shade of your hair depends on the mixture of pigments that area unit gift. If there aren’t any pigment granules within the cortex, it’s yellowish-white at the roots. this can be as a result of keratin itself is slightly yellow and is that the sole factor contributing to the hair color. grey hair isn’t truly gray; it simply appears that manner. It’s truly a combination of white and colored hairs that seem grey once seen along. There area unit four basic ways in which to change the color of your hair: temporary, semipermanent and permanent color, and lightening. the consequences these wear your hair vary from comparatively harmless to damaging.

Temporary Coloring: Temporary hair color lasts solely until the succeeding time you wash your hair. This method doesn’t contain any peroxides. Temporary color works by coating your cuticles with a pigment composed of enormous molecules. This forms a movie or a stain on your hair. The coloring is slightly acidic, therefore once the stain is applied, the cuticles snap border response to the present acidic setting. Keeping the cuticles tightly shut ensures that the massive molecules of the stain can’t get within, to the cortex. the color molecules sit on the cuticle with nothing to anchor them, like sticky jellybeans on a fence. They wash away simply with succeeding shampooing. thanks to the coating on your hair (as well as any doubtless damaging ingredients which will be within the formula), temporary hair coloring is also drying to your hair.

Semi-permanent Color: Semi-permanent treatments will last from six to 12 weeks. These don’t use any peroxides to figure however area unit slightly basic. Applying a long color causes your hair shaft to swell slightly in response to the basic setting, and this causes the cuticles to open slightly, like several drawbridges. the color molecules used area unit little so that they pass simply within the raised cuticles. a rather neutral-to-acidic rinse is applied to shut the cuticles once more, caparison the color molecules between the shingles. once your hair is washed, the cuticles open slightly. This allows the small dye molecules to slide out. Over time and with continual washings, these molecules area unit washed away. as a result of this, long colors can’t modification the color of your hair, solely stain it. betting on however basic the formula is, long hair coloring could cause minor harm to your cuticles, further as cause some waterlessness to your hair.

Permanent Dyes: Permanent dyes area unit basic, usually employing an extremely basic compound like ammonium hydroxide, or ethanolamine, to cause the hair shaft to swell and open the cuticles. The pH scale required so as for the dye to figure is extremely high (about ten to 11) enough to cause harm to your hair with this pH scale alone. (I discuss what precisely pH scale suggests that anon during this chapter, beneath “About the pH scale utilized in Perms and Relaxers.”) The coloring molecules of permanent dyes begin out innocently enough: little and colorless. directly before the dye is applied to your hair, it’s mixed with peroxide to activate the color. as a result of the little size of the dye molecules, they simply pass between the scales of the opened cuticles, into the cortex. The supplementary peroxide reacts with these molecules, creating them expand and switch coloured. These swollen molecules area unit currently too plump to pass back through the cuticle, so that they stay for good lodged in situ. regardless of however moisturizing or natural the box of dye tells you that it’s, the high pH required to swell your hair so as to open your cuticles for the dye to figure (not to say the element peroxide) can harm your hair.

Lightening Your Hair: Hair is typically lightened with peroxide, as a result of it reacts with the animal pigment pigments within the cortex. An extremely basic answer (with a pH scale of ten to 11), usually created with ammonia, is 1st applied to your hair. This answer opens your cuticles and prompts the peroxide to try to its factor and to react quicker with the animal pigment pigments. once the animal pigment grains react with the peroxide, they flip colorless, like very little ghosts. Once altered, the spiritual animal pigment granules area unit dissolved within the basic setting and area unit rinsed from the hair, effort very little empty spots within the cortex. The peroxide reacts otherwise with the eumelanin than with the phaeomelanin pigments in your hair. Peroxide lightens the darker eumelanin quicker than it will the lighter-colored phaeomelanin. as a result of each area unit gift in variable amounts in your hair, the darker eumelanin is quickly modified to a colorless substance that’s rinsed away. This exposes the additional stubborn red- or yellow-colored phaeomelanin molecules that were antecedently hidden behind the darker eumelanin pigments. If an additional radical modification of color is desired, a ballroom dance method is performed. This involves remotion all of the natural color from your hair with a robust peroxide answer. The sturdy answer removes each the eumelanin and also the phaeomelanin from your hair so replaces them with a brand new color. in step with hair and skin knowledgeable Dr. John Gray, bleaching destroys the supermolecule, keratin, that produces up your hair. As represented in chapter two, ceratin is that the terrible foundation of the hair’s structure. The harm from this method may be severe and might flip antecedently soft hair into brittle fodder.

The Aftereffects of Lightening: something that with chemicals alters your hair can cause harm. Lightening your hair with peroxides, particularly the powerful ones that area unit required to drastically lighten your hair by many shades, will rupture disulfide bonds that hold the fiber of your hair along. when concerning of lightening, your cuticles become weakened. once they’re weakened, even straightforward things like hair care will simply tear them off. Bleaching your hair can lead to it turning into dry and brittle and additional liable to tangling. it’ll additionally become rougher to the bit. The additional drastically your hair is bleached, the rougher it’ll feel. this suggests your cuticles are not any longer lying flat. These raised cuticles area unit before long torn off and scoured away through regular hair care, an effort the cortex exposed. Once exposed, the cortex quickly unravels. In lepton micrograph photos, it’s just like the cortexes have exploded.
