The Reality of Results: What to Expect

A common concern in the beauty community involves the distinction between various formulas. While some prostaglandin derived serums work by forcing follicles into an active state, they often come with a trade-off in terms of sensitivity. Conversely, using peptide-based infused formulas is safe because they focus on nourishing the hair rather than altering the biological cycle.
