Does eating seaweed such as wakame seaweed and hijiki make your hair grow?
Actually, it is “x”. Although it is an important ingredient, it has no effect on hair growth. Take the protein first.
Seaweeds such as seaweed, wakame seaweed, and hijiki contain many of the ingredients necessary for hair growth, such as iron, copper, and zinc. But eating lots of seaweed won’t make your hair grow.
The most important thing for hair is protein, which is the main component of hair. The ingested nutrients are first used by the internal organs, which are essential for life support, and the supply to the hair is postponed, so it is important to take that amount properly.
Think of seaweed, along with other vitamin-rich ingredients, as supplementary ingredients to keep your hair healthy.
Ingredients rich in nutrients that are especially important for hair
- Meat (lean meat)
- Blue fish
- eggs etc.
- oysters, beef
- Seaweed such as wakame seaweed, rock glue, etc.
- soy products
- clam etc.
- Green and yellow vegetables
- Citrus fruits, etc.
Should I avoid greasy food because it causes thinning hair?
Actually, it is “x”. As long as you don’t overdo it, don’t worry too much. Moderate lipids are important nutrients for hair.
Eating greasy foods doesn’t necessarily make your skin oily. Middle-aged and elderly people do not eat much meat because they feel heavy on their stomachs, and they tend to lack fat. Appropriate fat content is important for maintaining the quality of hair.
However, excess lipids accumulate in the blood as triglycerides, impairing blood flow. This can lead to hair loss and thinning hair because the hair matrix cells that produce hair will not be supplied with nutrients.
If your health check reveals that your triglycerides are high, or if you are overweight, avoid fatty meats, junk foods, and other oxidized lipids (see the list below for other dietary habits that are bad for your hair).
Eating habits that are bad for your hair
- Junk food Junk food
such as hamburgers tends to be high in fat and salt and lack vitamins and minerals. Don’t take too much.
- Eating late at night Eating
late at night causes poor sleep due to digestion and absorption, which adversely affects hair growth. Refrain from eating after 22:00.
- Too much
caffeine Caffeine has a cooling effect on the body and can worsen blood flow to the scalp. Be careful not to take too much or take it before going to bed.
If I use a good hair care agent, will my hair not turn gray?
It is “△”. It can be cared for to some extent, but it is important to deliver nutrition from the base of the scalp first.
Hair dryness and damage can be treated to some extent with treatment agents. However, more than that, it is important that the scalp, which is the foundation, is healthy and that the hair is well nourished. Beware of popular sugar-restricted diets.
In particular, complex carbohydrates contained in grains and potatoes are important nutrients as an energy source for hair. Take the five major nutrients for your hair and scalp and change your unbalanced diet.
Is it true that white hairs grow when you pull them out?
Actually, it is “x”. It won’t increase, but it may lead to thinning hair in the future.
The source of hair color, melanocytes, which produce melanin pigment, are not damaged by pulling out gray hairs, so gray hairs do not “grow when pulled out”. However, forcibly pulling out gray hairs can damage the hair roots and lead to thinning hair in the future.
Does Stress Affect Gray Hair?
Trivia about hair (1) What is the relationship between gray hair and stress?
The truth is still unknown.
The cause of gray hair and the reason for the decline in melanocyte function are unknown. People often ask me, ” Is it true that when you pull out your gray hairs, you get more gray hairs? “
Trivia about hair (2) Do you need to clean your brush?
We recommend washing once a month with your regular shampoo.
One thing that many people tend to overlook is keeping their brushes clean. If you use a brush with sebum and dust accumulated, it will cause an increase in bacteria on the scalp. Remove tangled hair from the brush and wash it at least once a month.
It is recommended to soak the brush in hot water with the shampoo that you normally use, and then use a toothbrush to wash the brush between the eyes. It’s a good idea to take advantage of bath time.
[Hair Concerns Q&A] In the second part, we will introduce the correct shampoo method and how to use a comb.
