In this short tutorial, Jen Booth explains that hair is composed of 70‑80% protein bonds and introduces a simple at‑home stretch test to diagnose protein deficiency. She demonstrates pulling a strand of hair, stretching it, and observing how it returns to its natural shape. If the hair breaks, it signals a definite need for protein; if it only partially returns, protein is likely still needed; if it fully returns, protein levels are probably sufficient. Based on the test results, she recommends two salon products—Kerastase Ciment Thermique and Redken Anti‑Snap—to replenish protein bonds, and advises viewers to consult their stylist for personalized treatment.
