STORY AT-A-GLANCE
Healthy hair, skin and nails depend on three main structural proteins: solubilized keratin, collagen peptides and elastin, but there are other plant-based supplements that benefit these areas for more vibrant health
Other integrative interventions include extracts from the herb Polypodium leucotomos, a plant-based supplement for sensitive skin, nicotinamide (aka niacinamide) for skin cancer protection and phytoceramides (plant-derived lipids)
Factors that cause problems for your hair, skin and nails fall into two categories: intrinsic factors, such as the aging process, and fluctuating hormone levels
Extrinsic factors include ultraviolet (UV) radiation from sun exposure, free radical damage and increased enzyme activity that breaks down collagen and elastin; air pollution and smoking are also “outside” forces that cause skin damage
A combination of specific supplements, such as collagen, biotin, vitamin D and iron, can help strengthen your hair, skin and nails from the inside out
