Which Vitamin Deficiency Causes Hair Loss?

January 29, 2024

Hair loss can be a distressing experience, truly affecting your appearance. While hair loss has various causes, one often overlooked factor is vitamin deficiencies. At Vancouver Laser, we understand the impact of vitamin imbalances on hair health and are here to shed light on this issue. Let’s explore how vitamin deficiencies can lead to hair loss, and we’ll provide insights into potential solutions and treatments.

Understanding Hair Loss and Its Causes

Losing hair is a natural part of the hair growth cycle. However, when the rate of hair loss exceeds the rate of hair growth, it can result in thinning hair or balding patches. Hair loss can be caused by multiple factors, including genetics, hormonal changes, medical conditions, and even poor nutrition. It’s essential to recognize that vitamin deficiencies can play a significant role in exacerbating hair loss.

Which Vitamin Deficiency Causes Hair Loss?


Iron deficiency is one of the most infamous causes of hair loss, especially among vegans and women with heavy periods. Iron is the raw material for making hemoglobin, a protein that helps carry oxygen to all cells in your body, including those in your hair follicles. It also helps the body produce energy and supports healthy hair growth.  Studies have shown that vitamin deficiency causing hair loss can be proven. Iron deficiency anemia, a condition in which there are not enough red blood cells to carry oxygen to the boy’s tissue, is one common cause. This is because hair follicles require a steady supply of oxygen and nutrients to grow and maintain healthy hair.  It is recommended to consume iron-rich foods such as meat, poultry, fish, beans, and fortified cereals to prevent iron deficiency. Iron supplements may also be prescribed by your dermatologist in Vancouver Laser if you are at risk of deficiency.


Healthy hair follicle cells grow and divide over time. This process is called cell proliferation, and your body needs a healthy zinc supply to make this type of cell growth happen. Cell proliferation encourages hair growth and repair. Zinc is also required for other cell processes, such as creating new proteins that promote hair growth and aid hair follicle recovery.

Zinc can also stop hair from entering the final catagen phase of growth. As a result, it’s been linked with several types of hair loss.

Vitamin D

Hair follicles contain vitamin D receptors. When you have healthy vitamin D levels, these receptors help regulate your hair growth cycle and create healthy hair follicles. Studies show that not having vitamin D receptors can lead to alopecia.

Most people do have these receptors. However, if you don’t have enough vitamin D, they may not work as they should. This can make your hair enter the shedding (or telogen) phase prematurely, creating the appearance of thinning hair.

Vitamin B12

Vitamin B12 deficiency is often thought to be one of the causes of hair loss. After all, this micronutrient is needed for deoxyribonucleic acid (DNA) synthesis and red blood cell production, both of which are critical to growing new hair fibers. Vitamin B12 is a water-soluble vitamin that plays a crucial role in DNA synthesis, red blood cell formation, and nerve function. It also helps the body convert food into energy and supports healthy hair growth.

Vitamin E

Vitamin E is an essential antioxidant. Antioxidants neutralize free radicals that damage follicle cells. Free radicals are highly unstable chemical entities that react with other molecules in your body, leading to oxidative stress which can facilitate the development of alopecia.

Vitamin E is the only micronutrient where dietary supplements are proven to have a positive effect on hair growth in patients, even if you don’t have a nutritional deficiency.

If you’re experiencing hair loss due to vitamin deficiencies, there are steps you can take to address the issue. Incorporating a balanced diet rich in vitamins and minerals is crucial in preventing hair loss. Including foods like fatty fish (a source of vitamin D), eggs (a source of biotin), lean meats (a source of iron), and nuts (a source of zinc) can contribute to healthier hair.
