Can collagen reverse hair loss?

No, collagen cannot reverse hair loss, as there is no strong evidence it regrows lost hair or restores thinning areas. Some studies show it may reduce hair shedding by up to 28% after 8 weeks when combined with other ingredients like biotin. However, evidence for significant regrowth is limited, and results vary.

Key points:

• Collagen supplements reduced hair fall by 28% in one study after 56 days compared to placebo.
• It may strengthen hair and support scalp health by providing building blocks for keratin.
• Research shows potential improvements in hair thickness and volume, but not reversal of loss.
• More studies are needed to confirm benefits as a standalone treatment.
