Understanding Hair Growth and Loss

Before diving into it, are you curious about the basics of hair growth and hair loss?

Everyone’s hair goes through cycles that include growth, resting, and shedding phases. Some factors influence these cycles from time to time.

For example, stress, genetics, hormonal changes, and, yes, nutritional deficiencies affect your hair growth. In other words, these can cause you to lose hair!

Key Vitamins Linked to Hair Loss

  • Vitamin D: Don’t think that sunlight is only good for your soul.Because the vitamin D you get from the sun is important for your hair! Research also indicates a strong link between vitamin D deficiency and alopecia areata, an autoimmune condition characterized by severe hair loss. So, D vitamin deficiency causes hair loss!
  • Vitamin B12: Did you know that vitamin B12 helps the formation of red blood cells that carry oxygen to your scalp? Pay attention to this vitamin as vitamin B12 deficiency will cause thinning hair and hair loss in you!
  • Iron: You have definitely heard about the importance of iron, which is not classified as a vitamin, for hair health. That’s why we wanted to add iron to the list in this article. Iron contributes to hair growth because it helps hemoglobin production. However, if you have low iron levels, it can lead to anemia and you will have to deal with the problem of hair loss.

Diagnosing Vitamin Deficiency Causes Hair Loss

As you can imagine, you need to have blood tests. The blood test will tell you if you are lacking important nutrients. Don’t self-diagnose! Always ask a doctor for advice.

Treatment and Management

When you read the following you will have ideas about treatment:

  • When a vitamin deficiency causes hair loss is detected, your health care provider may recommend supplements or dietary changes to help you get your levels back on track.
  • For vitamin D, spending more time in the sun or eating fortified foods can help.
  • B12 is abundant in animal products, while iron can be found in leafy greens, beans and red meat.
