Hair Color Permanent, Demi, Semi: What’s the Difference?

Hair Color, What’s the difference?

The statistics tell us 80% of women are choosing to color their hair today. This could be a result of baby boomers holding off the inevitalbe gray hairs or maybe just trying to enhance tones from dull and lifeless to bright and vibrant. Whatever the reason, once you’ve made the decision to color yourt hair, you’ll have another immediate decision to make . . . what type of hair color should you use.  There are three types of hair color to choose from when considering taking the plunge,.

Permanent hair color leaves a stronger line of demarcation, and does not fade out. It is the most difficult color type to maintain since on average our hair grows a ¼ inch per month. The ammonia is an alkalizer that opens the cuticle layer, allowing the hair color molecules to penetrate into the cortex; this is where the color molecules remain. Alkaline is the ammonia in hair color that opens the cuticle and allows the color to penetrate. This process opens the cuticle and may leave your hair frizzy and rough-looking. This is why following with a conditioner is always necessary. The conditioner closes the cuticle which allows it to lay flat increasing shine and easing style time.

A semi permanent hair color does not penetrate into the cortex; it just coats the outside but only lasts up to 8 shampoos. This would be used more for someone not wanting a commitment to a coloring at all but wants to add just a little something to their current hair style.

A demi permanent hair color gently penetrates the cortex, and depending on how dry and/or damaged your hair is, it could last longer or even get darker than expected. A demi permanent hair color is usually used when you want to enhance your current hair type and you’re not quite read to make a commitment to a permanent hair color. Demi permanent hair color will usually last a little longer than a semi permanent hair color but rinses out after several weeks.

This brings me to what I believe is a very important step in protecting any hair color treatment that is overlooked by many. Not only does your hair need a great shampoo and conditioner, but what you’re putting on your hair before using heat is just as crucial. Not using a product to protect your hair prior to blow drying or flat ironing is more damaging to your hair than anything else that you could do to your hair. Especially since a majority of our blow dryers can reach 140 degrees and our flat irons a whopping 450 degrees. Making sure your styling aid provides thermal protection is a must when trying to preserve your beautiful hair color!

In my 10 years as a hair stylist I have worked with many leave-in conditioners and styling products that provide thermal protection. There are a lot of good ones in today’s market! I recently was given the opportunity to take part in the development of a new product which I am excited about called Keracolor which provides thermal protection and enhances hair color. I would recommend it to anyone looking for a new leave-in!

How to Avoid These Hair Color Mistakes

How to Avoid These 3 Top Hair Color Mistakes

Have you ever colored your hair and ended up with a result nothing like what you had hoped for?  I know it’s devastating. I’ve done it myself, before getting into the business, as well as a mistake or two while on the learning curve to becoming  a better hair colorist.

Hair coloring is an art and experienced hair colorists are your best bet to get top results. If you’re looking to get a hair color like Jennifer Anniston’s, Jennifer Lopez’s or the like, don’t try it at home. If you choose to color your own hair, take the time to read directions carefully, do the strand test and bookmark this article to avoid these top hair color mistakes we see in the hair salon all the time!

A woman who's hair color turned too darkMistake # 1 – Coloring Your Hair Too Dark

Coloring hair too dark is a common mistake (especially for novices) and can be expensive and difficult to correct. The majority of mistakes we see may have been avoided by taking these steps:

  •  Choose a temporary, semi-permanent, or demi-permanent color. These hair colors are the most gentle on your hair and should be your first choice. Unlike permanent hair color, these colors are more gentle and will gradually fade over time. Temporary, semi-permanent, or demi-permanent hair colors can only add color to your existing hair color and will not lift or lighten your color. Are you trying to lighten your natural hair color or cover gray completely?  If so, permanent hair color will need to be used because these types of colors only blend grays and deposit color.
  •  Choose a hair color one or two levels lighter than your desired end result. The color you add will look darker on your hair than on the box or  color swatch Why? Remember you are adding color on top of your own hair color. (See what happens when you add a second colored pencil on top of the first color . . . not an exact science but you get the idea.)
  • What if it doesn’t turn out dark enough? It’s a good idea to wait a couple of weeks or  when your hair is healthy enough before coloring it again. It is much easier to darken artificial hair color as opposed to lightening it.

A woman who's hair color has turned orangeMistake # 2 – How to Avoid Orange Hair Color

Fixing hair that has turned orange from coloring can be done . . . but not by most DIY’ers . . . it is a delicate undertaking. The reason is that in order to get it right, you need to understand principles of the color wheel, be experienced with bleach lifting and timing and/or be familiar with toners. Read more about how to fix orange hair color here, but below are steps to avoid this color mistake before it happens.

  • When changing hair color by two levels or more, see a professional colorist. The clients I’ve seen most often with this problem, happened when they tried to lighten or darken their hair by two levels or more. Just don’t do it!  It’s a complicated process, that is unique to each head of hair, to create a beautiful hair color change of two levels or more. And, the difference between getting a beautiful color or an orange mess, is in the hands of doer. Let the professional get you there and if they happen to get it wrong, someone in the salon will fix it. If you get it wrong, it can be a costly and/or painful error to fix. Once your hair has been changed successfully, the upkeep will be easier too.
  • It’s a crap-shoot and can be harmful to use hair lighteners or hair color removers at home.  These products can do far worse things to your hair than turning it orange.  They can severely damage your hair and cause it to break off, depending on how they are used and the condition of your hair.  A color remover, despite its name, will not return your hair to its original hair color shade. It can only remove some of the color from semi and demi-permanent colors, they won’t remove permanent hair color.

Infogarphic showing underlying hair color pigments and the color wheel

  • Know the underlying pigment of your hair.  The underlying pigment of your hair is most important to  know when you are formulating your own hair color. It is the contributing pigment (color) that naturally occurs in your hair. You need to understand the color chart to get this right.

For instance, a person lifting their hair color to a medium brown, level 5, has an orange underlying pigment.  They have two options; they can emphasize the orange or neutralize it.  To emphasize an underlying pigment choose one of its complimentary colors, the colors that are next to it on the color wheel.  To neutralize the tone, choose the color that it directly across from it on the color wheel.   In this case, red and yellow are the complimentary colors, so if a person coloring their hair medium brown wants to emphasize their orange underlying pigment, they should choose a hair color with gold or red tones.  Blue is directly across from orange on the color wheel, so a hair color with a blue ash base should be used to neutralize any unwanted orange tones.

Mistake # 3 – Your Hair Color Did Not Cover the Gray

If you’ve used a hair color that didn’t cover your grays completely it doesn’t mean you need to use a darker hair color, as many people may think. It’s more likely one of these reasons . . . not to worry, this one is usually an easy fix.

  •  It’s time to use a permanent hair color.  Temporary, semi-permanent, and demi-permanent hair colors will allow you to blend gray, but they will not cover it completely. Temporary colors are the best choice to use until they don’t do the job any longer . . . that’s the time to switch to permanent hair color.
  • You may need to bring all of the primary colors back into the hair.  White hair is like the color white.  They both are absent of color.  Finding a hair color that is rich in the primary colors will give your grays a natural, rich look that is able to hold onto the color.  Most color lines have a neutral series that best cover gray.  Check the manufacturer’s directions, or call the 800#  for best results.
  • Follow the manufacturer’s directions.   Although using a neutral tone hair color is the most common way to cover grays, it is not always the case. Follow the manufacturer’s directions to ensure complete gray coverage.

Are you still not 100% sure of a hair color?  Before coloring your hair, always perform a strand test.  Apply small amount of the color to a small section of your hair, preferably somewhere inconspicuous. Make sure that you mix the color in the correct ratio and leave it on the full length of time.  If this section comes out perfect, you’re ready to color the rest of your hair.  Good luck!

Emma Stone should get an award for having the best hair color. The rich, auburn color brightens her complexion, allowing her skin to glow with radiance.

Are you inspired by Emma’s fabulous auburn hair color? Try something new this year and give red hair a chance. Auburn and copper tones, similar to Emma’s, look the best on people with warm skin tones. Burgundy and violet tones are red shades that will best compliment those with cool skin tones. Do you love the look, but you are not sure about taking the leap? Try a warm brown or strawberry blonde hair color or highlights. Who said blondes have more fun?

Kelly Osborne at the Golden Globes with a grey hair colorWorst Overall Hair Color

Kelly Osborne was far from runner-up with this hair color. Her grey hair color, with purplish, bluish undertones was a wash-out! This color washed out her skin tone and added years to her appearance.

Are you thinking about going platinum? If you are, think of Christina Aguilera, not Kelly Osborne. This shade looks best on those with cool skin tones. Do you want ultra-light hair, but you have warm toned skin? A light golden blonde hair color will best flatter your skin tone.

This year the award for the most fabulous dark brown hair color goes to Jessica Biel. Her hair color looked stunning!

Do you love Jessica’s deep brown hair? This is the season to go darker with your hair color. A deep brown, like Jessica Biel’s, looks the best on those with cool skin tones. Red brown hair colors look very similar and are an excellent alternative for those with warm toned skin.

Would you like brown hair that makes your eyes sparkle like Sophia’s? Use a golden hair color to enhance warm skin tones and bring out your eye color. Don’t have warm toned skin? Use a medium ash brown hair color to enhance your features and look your best.

Elle Macpherson at the Golden Globes with blonde hairBest Blonde Hair Color

Elle Macpherson’s sexy golden locks beat her fellow celebrities in this category, but it was a close call. We also loved Reese Witherspoon and Charlize Therone’s blonde hair color about as much . . . they were both runner-ups in our book.

Do you want beautiful blonde hair? Women with warm skin tones, like Elle Macpherson, look the best with golden blonde hair. To achieve the same award-winning style for those with cool skin tones, add honey colored highlights to a sandy blonde color. The honey color will add warmth and dimension.

Nichole Kidman can’t be beat when she goes with this hue; she looked ravishing with her strawberry blonde hair color! It was also the perfect look with her elegant white and gold dress.

Strawberry blonde hair looks best on those with warm skin tones. Do you have a cool skin tone? The subtle warm tones in beige blonde hair color make it a wonderful alternative for you.
