How we score →Yay
3 experts · Moderate agreementWhat the gurus are saying
This oil earns praise for being lightweight yet deeply hydrating, with a smoothing effect that works especially well in summer heat. Gurus found it makes hair silkier and shinier, though one notes it lands somewhere between pleasant and unremarkable, and it may feel heavy on fine or low-volume hair. The clean, floral scent fades quickly without lingering.
