In addition to genetic factors, stress and aging, the cause of gray hair growing a lot and quickly can also be due to a lack of nutrients.
1. Iron
Iron is one of the important nutrients that help the body produce red blood cells. Red blood cells have the function of transporting oxygen and providing energy to the body's cells. When there is a lack of iron, the supply of nutrients may not be enough, leading to hair follicles not being able to develop healthily, slowing down the hair growth process, or causing gray hair. Dark green vegetables such as watercress, spinach, cauliflower... are ideal sources of iron that can be added to the daily diet. In addition, this substance is also abundant in meat and animal organs.
2. Vitamin B12
Like iron, vitamin B12 plays an essential role in the formation of red blood cells. However, the human body cannot produce vitamin B12 on its own and must be supplemented through diet. If this vitamin is lacking, the scalp will not receive enough oxygen and nutrients, not only affecting the scalp's metabolism but also preventing healthy hair and hair pigment growth. You should supplement meat, seafood, shellfish, and animal liver to increase this substance for the body.
3. Protein
Protein is the most important component of hair. If there is a lack of protein, hair will not only become dry and weak but also turn gray and fall out. This condition is likely to occur in people who are trying to lose weight or are on a strict diet. You should add seafood, milk, eggs, meat, or beans to your diet because these are all sources of high-quality protein.
4. Iodine
In addition to preventing thyroid problems, iodine is also a nutrient that promotes healthy hair growth. If the body lacks iodine, the function of hair follicles will decline, unable to synthesize melanin, causing hair to turn gray. You can supplement this substance through foods such as seaweed, kelp, spinach, shrimp, sea fish... to support healthy hair follicle growth.
Algae and seaweed are ideal sources of iodine for the body.5. Tyrosine
Tyrosine is one of the important ingredients that help the body produce melanin, the pigment that maintains the black color of hair. When tyrosine is not enough tyrosine, melanin will not be produced, causing gray hair to appear more and faster. Long-term tyrosine deficiency can also make you feel depressed and lethargic. Animal meat, nuts, cheese, sesame, and peanuts are sources of tyrosine that can be easily added to your daily diet.
