How do nutritional deficiencies affect hair loss?

Several nutrients play a key role in hair health. Nutrition deficiencies that impact hair health include:

• Iron – Lack of iron can cause anemia, which limits oxygen to hair-growing cells.
• Zinc – A zinc deficiency can lead to brittle, dry hair that breaks easily.
• Vitamin D – Since this vitamin plays a role in the hair growth cycle, a deficiency can cause hair loss.
• Vitamin A – This vitamin activates hair follicles, so a deficiency can impact hair growth.
• Biotin (Vitamin B7) – This is one of the most commonly known nutrients that impacts hair health. Without Biotin, hair may become weakened and brittle and fall out more easily.

Defy Medical offers access to nutritional testing to identify a deficiency, as well as high-quality supplements to replenish nutrient levels.
