Collagen is a protein that is found in the skin, hair, and nails. It plays a role in the structure and strength of these tissues, and as such, there is some evidence to suggest that collagen may be beneficial for hair health.
Collagen is composed of amino acids, including glycine, proline, and hydroxyproline, which are essential building blocks for healthy hair growth. These amino acids are also found in keratin, the protein that makes up the majority of hair.
Research has shown that collagen supplementation may help to improve hair thickness, texture, and overall health. One study found that women who took a collagen supplement daily for 12 weeks had a significant increase in hair thickness and density compared to those who took a placebo.
Collagen may also help to prevent hair loss by reducing inflammation and oxidative stress in the body. These factors can contribute to hair loss by damaging hair follicles and interfering with the hair growth cycle.
Overall, while more research is needed to fully understand the effects of collagen on hair health, there is some evidence to suggest that it may be beneficial for improving hair thickness, texture, and overall health. It is always important to talk to a healthcare professional before starting any new supplements or treatments for hair health.
