THE GUT BACTERIA AND HAIR GROWTH CONNECTION
Many studies have shown that our gut bacteria is vital for the uptake of may nutrients vital for healthy hair growth. Some studies have shown that the numbers of ‘good bacteria’ in our gut support a normal hair growth cycle.
In one study, supplementation with probiotic Lactobacillus reuteri increased anagen hair follicle counts by 106% when compared to a control group. Researchers determined that the probiotic-fed male mice had 74% of their hairs in the active, anagen phase, while the control group only had 36%. In comparison, 64% of hairs on the mice in the non-probiotic group were in the non-growth, telogen phase .
A study by Dr. James Chen showed that wiping out the gut microbiota with antibiotics, prevented alopecia areata in a study of mice. This provides evidence that an overgrowth of pathogenic bacteria within the population of the gut microbiota plays a role in hair loss.
