Is expensive bonding oil worth it over a budget argan oil?

It depends on your goal. Drugstore argan oils (OGX, Cliganic) earn strong ratings for shine and softness at a fraction of the price. Bonding oils like Olaplex N°.7 carry claims around strengthening and color vibrancy that pure carrier oils don't make. For everyday shine, budget options satisfy most shoppers; for color-treated or chemically damaged hair, many reviewers gravitate to the pricier bonding formulas.
