Xtressé is a premium, dermatologist-developed hair health brand primarily known for its biotin-free nutrient gummies designed to combat hair thinning and shedding at a cellular level. Formulated by a panel of leading hair restoration specialists and PhDs, the brand focuses on regenerative medicine to treat the underlying causes of hair loss—such as cellular inflammation, oxidative stress, and hormonal imbalances—rather than just providing basic vitamin deficiencies.
