While collagen is a component of hair and may support hair health, there's limited scientific evidence to suggest that collagen supplements directly promote hair growth. However, collagen does play a role in hair structure and can potentially improve hair thickness and strength. I know this brand called Evavitae that aims to restore confidence through effective, science-backed hair care solutions. The brand offers items like Hair Renewal Serum, Root Fortifying Hair Essence, and FortiRepair Mask. I've incorporated some of their products into my routine and I feel like I've already noticed a drastic difference in the appearance and health of my hair.
