When Gray Hair Starts to Appear and How to Prevent It

As aging occurs, one of the representative changes that is sometimes regarded as a natural phenomenon is the start of new hair growing in white. In the past, it was often seen as something that appears as people get older and was relatively common due to aging, but recently, the time when gray hair starts to appear can be commonly seen not only in middle-aged and older adults but also in younger age groups.

The timing and reasons can vary from person to person, and the causes can also differ slightly depending on age group. The most typical cause of hair turning white is a lack of melanin pigment. In young people, melanocytes are black-brown, so they maintain black natural hair. Because this is determined by genes, the timing of gray hair can also be considered to include genetic factors.

Also, once it starts to appear, the possibility of black hair growing back again is slim, so it is best to protect and care for as much black-brown natural hair as possible while there is still plenty left.

It is usually regarded as one process that naturally comes with age, and its distribution tends to be symmetrical overall and spread evenly. Because of this, it can change to the point of being described as turning white overall, but when it appears in people at a young age, it is usually called premature gray hair.

Unlike white hair, premature gray hair does not spread out evenly; instead, it tends to appear here and there in one or two strands at a time. It may seem to appear suddenly and make the hair look generally white, but the timing of gray hair progresses in order. It usually appears first around the sides, then the front, and then the back, and especially around the area under or beside the ears.

The reason for this is that, compared with other parts of the scalp, those areas have thinner skin and therefore fewer blood vessels. The amount of white hair becoming noticeably abundant is also commonly seen around the 40s. At that time, hair loss can also occur, so it is a period when you need to pay a little more attention to hair care.

In this way, natural hair turning white can be considered a natural change, but if you look more closely, you may be able to maintain healthy black hair for a long time. One reason you should pay attention is that, although it can be difficult, it may also help infer your overall health condition. If a large amount appears in one area or appears in several areas, your nutritional status or blood circulation may not be good, and lack of sleep and stress may also be involved.

It can also appear due to excessive dieting, which can be considered a cause of nutritional deficiency. Among these, stress is probably one of the most significant factors. Since it is also regarded as the source of many illnesses, it can be said to be related to the timing when gray hair starts to appear. If you are under a lot of mental stress, blood vessels constrict and blood circulation does not function properly, so nutrition is not smoothly delivered to the hair roots, which can make the period come sooner.

Stress also causes free radicals to form more quickly, accelerating aging throughout the body. Because aging progresses faster, natural hair can become white more easily. In addition, if the phenomenon of natural hair turning white on the sides increases sharply, high blood pressure may be suspected. Even if this does not mean that everyone who experiences this symptom has high blood pressure, it is recommended that you check it at least once.

Also, if it begins to appear on the back of the head, there may be a risk of stroke. If hair loss becomes severe or the back of the neck feels stiff, it would be a good idea to visit a relevant medical institution. Thyroid disease or hormonal imbalance can also make the timing of gray hair appear even earlier. In general, when thyroid function declines, it reduces the function of the cells that produce melanin pigment, which can lead to white hair growing.

Also, if you are overweight or obese, have metabolic syndrome with poor metabolism, or are dealing with osteoporosis, oxidative stress increases and melanocyte function declines, which can cause hair color to turn white. And if you have pernicious anemia, you are in a state of vitamin deficiency, so cellular function declines and white hair may begin to grow.

Therefore, even if you do not have genetic factors, if white hair appears in a specific area, please keep in mind that it is also necessary to check your physical condition.

Some people forcibly pluck out natural white hairs that are clearly visible to the eye in order to remove them. However, if they are removed incorrectly, inflammation can occur in the hair follicles, causing nearby hair to fall out and potentially leading to hair loss, so caution is needed. Therefore, since low-irritation hair dyes are now widely available, covering the hair with dye may be a better method than plucking.

We cannot prevent or stop the changes that aging brings to our bodies, but the timing when gray hair starts to appear can be delayed through everyday habits and preventive measures. It is better to wash your hair in the evening rather than in the morning to promote healthy hair growth and development, and completely drying it is also one of the right methods.

In addition, regularly massaging the scalp to help blood circulation and provide healthy stimulation is also beneficial. Eating black foods, which are known to help maintain strong hair, such as black sesame, black beans, seaweed, eggplant, and mushrooms, may also be helpful.

Natural hair is mainly made of protein. Therefore, since your condition is determined by whether you consume enough protein and how much you eat, please keep in mind that it is better to eat a balanced diet carefully so that it does not lead to deficiency or shortage.
