Is biotin or collagen better for hair loss?

Between biotin and collagen, biotin is much better for thinning hair. It works to improve the thickness and strength of hair and is absorbed much better than collagen in most cases. Biotin is also found in many foods and can be applied and absorbed topically. Collagen, on the other hand, improves your hair's texture and elasticity. To get maximum benefit from both, you can choose to take biotin and collagen together.

Both collagen and biotin are crucial for healthy hair. Biotin facilitates the breakdown of macronutrients required for cell growth and renewal so it would be great for thinning hair or alopecia. Collagen, on the other hand, is known for it's ant-aging properties and it boosts ketatin production by providing amino acids and proteins. It is ideal for improving hair elasticity and texture. To get the benefits of both, you can take a supplement like Hairprin which combines both nutrients.
