The red pigment of their hair may be natural or due to effects such as deficiency, malnutrition or exposure to radiation. The natural ginger-haired people are just about 3% of the population. This makes them easily noticeable. The ginger-hair is also coming under the fashion trends. Many worldwide celebrities are making serious effort in making their hair color red to show themselves distinct among the crowd.
There are also protests against these people being called ginger and being mocked at by the British society. They mainly argue why only the red heads are being demoralized and not the blondes. The people with ginger-hair are very short tempered. They may go into any level of temperament and even come for a big fight with you. So we have approach them with care. The ginger hair is at times genetically inherited or can also be due to changes in the melanocortin-1 receptor gene and chromosomes. The climates with scarce sunlight are generally suitable for people with ginger hair as they are easily susceptible to rashes and skin burns or even bruising. As we all know that the melanin in our skin helps us against ultraviolet radiation. These people with ginger hair do not have sufficient melanin in their skin to protect them leading to the damage of their DNA structure. These people also become aged very soon and start developing wrinkled skins at young age.
Again, music and fashion are both non-withstanding here.
