Gut inflammation and hair loss may be related in several ways.
One way is that gut inflammation can cause **scalp inflammation** by allowing bad bacteria to escape the gut and harm the scalp and hair follicles. Scalp inflammation can damage the hair growth cycle and lead to hair loss.
Another way is that gut inflammation can affect the **hormone levels** in the body, such as estrogen, testosterone and cortisol. These hormones are important for regulating the different phases of hair growth: anagen (growth), catagen (transition) and telogen (rest). Imbalanced hormone levels can disrupt the hair growth cycle and cause hair loss.
A third way is that gut inflammation can impair the **nutrient absorption** in the intestine by altering the permeability of the intestinal wall. Nutrients such as biotin, iron, zinc and protein are essential for healthy hair. Poor nutrient absorption can lead to hair thinning and loss.
Therefore, gut inflammation and hair loss may be connected by affecting the scalp health, hormone levels and nutrient absorption that are vital for hair growth.
