Beautiful hair doesn’t just happen; it requires care. It can be dried by chemicals, sun and chlorine, for example. Diet is important also, because the most beautiful hair is healthy hair. Hair care doesn’t have to be expensive, though a visit to a beauty salon for a good cut is probably the best starting point for achieving beautiful hair.
Red Heads Are Mutants
In the late 1990s, scientists discovered that a gene mutation causes redheadedness. Specifically, it’s a variant of the melanocortin 1 receptor (MC1R), one of the key proteins that determines hair and skin color. The mutated gene is recessive, so in order for someone to have red hair, she has to inherit two copies of the gene, one from each parent.
Lots of people, especially those with Northern European ancestry, carry one copy of MC1R, but relatively few carry the two copies required for flaming tresses. Red hair can occur in any ethnicity, but the greatest concentration of redheads originates in Northern Europe. Scotland has the highest percentage of natural redheads, with 13 percent and Ireland is a close second, with 10 percent. Only about 2 percent of people in the United States have naturally red hair.
Types of Hair Dye
There are actually three different types of hair dyes. They include:
- Temporary Hair Dye
- Semi-Permanent Hair Dye
- Permanent Hair Dye
Temporary dyes cover the surface of the hair but do not penetrate into the hair shaft. They generally only last for one or two washings.
Semi-permanent hair color is similar to temporary but it lasts for a longer time period. To make the color stay longer, it is applied first and then sealed using heat from the dryer for about 30 minutes. These tend to last for around one month.
Permanent dyes cause lasting chemical changes in the hair shaft. They are the most popular types of hair dye, because the color change lasts until the hair is replaced by new growth. Permanent dyes contain various colorless substances such as aromatic amines and phenols. In the presence of hydrogen peroxide, these substances go through a chemical reaction to become a dye.
There is a slight concern with semi-permanent and permanent dyes regarding cancer risks. Because darker dyes have higher concentrations of some chemicals that may cause cancer, these products are of greatest potential concern.
Hair Dyes Can Cause Asthma
Hair stylists are at risk of developing occupational asthma, both from the persulfates used in bleaches and PPD from hair dyes. Long term exposure sensitizes the airways, leading to asthma attacks on exposure to the chemicals.
A number of studies have confirmed this theory; finding that hair stylists have higher levels of asthma than the general population.
Hair Color No Longer Listed On Passports
You might not know that hair color used to be a required listing on passports, and that’s because 1968 was the last year Americans were asked to list that fact on their passport applications. People were dyeing their hair so often that the information became worthless.
Pool Chemicals Damage Hair
Dyed hair can become dry and dull from chemical dyes, but swimming and exposure to pool chemicals can also contribute damage to hair strands. Hair absorbs liquids like a sponge when exposed to water. When hair absorbs pool chemicals during swimming, it can become very dry from repeated exposure. Hair can even turn a green tint from copper found in pool chemicals.
How to Protect Your Hair from Pool Chemicals
Before the Swim
- Shower before entering the pool. Thoroughly saturate your hair by running your hair through your strands for up to five minutes.
- Apply a leave-in hair conditioner. Turn your head upside down and spray the conditioner throughout your hair. A leave-in conditioner will help coat hair strands, preventing pool chemicals from being absorbed into hair shafts.
- Brush the hair strands to ensure the conditioner is evenly distributed. Spray your hair a few more times if the hair does not feel soft and slick. Resume brushing until your hair feels slippery.
- Make a high ponytail by flipping your head upside down and gathering hair with your hands. Insure that your ponytail will be placed directly on top of your head. Use a hair tie to secure the hair. Start twisting your ponytail hair to make a bun. Keep twisting the ponytail until there is no more hair to twist. Secure the bun with the remaining hair tie.
- Put on your swimmer’s cap on by stretching it over the front of your head. Then lift the back part of the swimmer’s cap white stretching outward from your head and slide it down over the back of your hairline.
After the Swim
- Rinse your hair immediately after swimming. Stand under the shower for at least four minutes to insure that any pool chemicals that may have came into contact with you hair are rinsed out.
- Wash your hair with the clarifying shampoo. Follow the instructions on the bottle for the necessary time to allow the shampoo to penetrate hair strands.
- Apply a conditioner to replenish moisture into hair strands.
