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

This study investigated the effects of enzyme food and collagen on scalp hair in 60 middle-aged women over 12 weeks. Participants were divided into four groups: a control group, an enzyme food group, a collagen group, and a combined enzyme food and collagen group. The combined intake group showed significant improvements in hair metrics, including a 14.6% increase in the number of hairs per unit area and a 15.9% increase in hair thickness, outperforming the single intake groups. Additionally, hair absorbance and color metrics improved significantly in the combined group. The study concluded that the combined intake of enzyme food and collagen was more effective than either supplement alone in enhancing scalp hair health in middle-aged women.
