TLDR KF2BL20 does not have proven benefits for maintaining normal hair.
The Panel on Dietetic Products, Nutrition and Allergies (NDA) reviewed a health claim related to KF2BL20, a combination of keratin, copper, zinc, niacin, pantothenic acid, pyridoxine, and D-biotin, for maintaining normal hair. Despite the claim that KF2BL20 helps reinforce hair strength and reduce hair loss, the Panel found the supporting study to be uncontrolled and insufficient for substantiating the claim. Consequently, the Panel concluded that there was no established cause and effect relationship between KF2BL20 consumption and the maintenance of normal hair.
