Improvement in Scalp Hair in Middle-Aged Women Using Oral Enzyme Food and Collagen

The study investigated the effects of combined intake of enzyme food and collagen on scalp hair in 60 middle-aged women, divided into four groups: control, enzyme food only, collagen only, and a combination of both. Over 12 weeks, the combined intake group showed significant improvements in hair density, thickness, tensile strength, and amino acid content compared to the control and single intake groups. Additionally, hair absorbance and color properties improved more in the combined group. The results suggested that the combination of enzyme food and collagen was more effective for enhancing scalp hair health in middle-aged women than either supplement alone.
