Study Finds Hydrolyzed Eggshell Membrane May Improve Hair And Skin Health

Eggshell membrane is primarily composed of fibrous proteins such as collagen type I. Eggshell membranes also contain glycosaminoglycans, such as dermatan sulfate, chondroitin sulfate, and hyaluron, as well as sulfated glycoproteins including hexosamines, such as glucosamine. A recent study suggests that supplementation with hydrolyzed eggshell membrane may help enhance the health of hair and facial skin appearance.

Participants included 88 adults between the ages of 35 and 65. Half of them took 450 mg of hydrolyzed eggshell membrane and the other half took a placebo daily for 12 weeks. Hair density and growth were measured at baseline, weeks 4, 8, and 12 using the TrichoScan HD. Skin quality was measured using the Canfield Visia-CR and the FACE-Q at baseline, weeks 4, 8, and 12.

Participants in the eggshell membrane group saw significant improvements in hair thickness and density at week 4, and continued to show further improvements through week 12. They also saw significant increases in hair growth and decreases in hair breakage, compared to the placebo group.

The eggshell group participants also saw improvements in the depth of wrinkles, crow’s feet, and skin tone evenness compared to the placebo group.

The study was conducted by researchers from Nova Southeastern University and Central Michigan University. It was published online ahead of print on January 6, 2020 in the Journal of Cosmetic Dermatology.
