How Do Nutritional Gaps Lead to Hair Loss?

How Do Nutritional Gaps Lead to Hair Loss? - Follicle Labs

Science supports several reasons for hair loss, and while it is generally blamed on genetic or chronic stress, what you consume, or your diet plays a huge role in hair health. 

Truthfully, hair follicles also require a balanced combination of nutrients to ensure that hair strands grow stronger and healthier. When a body lacks these necessary nutrients, thinning or shedding can be observed, and there is a considerable need to modify your diet to stop it from worsening.

Here are some of the most common nutritional deficiencies that contribute to hair loss and why:

1. Iron Deficiency

Iron is paramount for producing hemoglobin, which helps carry oxygen to your tissues and hair follicles, stimulating hair growth. Without sufficient iron, your hair follicles delay or slow down growth and cause strands to fall out easily due to low blood cell count. This deficiency is more common in women.

2. Biotin (Vitamin B7) Deficiency

Also known as Vitamin B7, biotin sustains the metabolism of fats, carbohydrates, and protein, particularly keratin production, the key nutrient in your hair structure. Low levels of biotin can weaken hair strands, make them brittle, and lead to increased hair fall. While rare, this deficiency can result from certain medications and dietary imbalances.

3. Protein Deficiency

Your hair is made of protein, so it makes sense that not getting enough in your diet can affect growth. Protein deficiency is commonly experienced by those who pursue a restrictive diet or have eating disorders, and their bodies prioritise fundamental functions over hair production.

 As a solution, obtaining food sources like meat, dairy, fish, and soy can support hair health. It is also helpful to use a quality hair loss serum to supplement external care while addressing internal protein levels.

4. Zinc Deficiency

Zinc plays an integral role in hair tissue growth repair and protein synthesis. It also maintains the oil glands around the follicles' proper functioning. Without enough zinc, hair loss and scalp problems like dandruff may arise, especially for those with poor diets. Hair growth serum may help in the short term, but restoring zinc levels through zinc-rich food intake is needed for long-term results.

5. Folic Acid Deficiency

Folic acid, or Vitamin B9, helps stimulate red blood cells and promotes healthy cell division, including hair follicles. Low levels can affect this process and produce more fragile strands, boosting hair shedding. A balanced diet focusing on folic acid can support overall health and benefit hair growth.
