Vitamin deficiency
The absence of Vitamin D can cause hair loss, leading to an autoimmune problem in the body. Vitamin D helps develop hair follicles, so hair loss occurs when there is an insufficient or total absence of vitamin D. Research done by health professionals showed that hair loss in women between the ages 19 and 46 years old was caused by insufficient levels of vitamin D. introduction of sufficient vitamin D to the body can help hair follicles develop properly, prevent hair from falling and as a result reverse the condition. The absence of iron, zinc, protein and other nutrients can lead to undeveloped hair follicles.
