How reviews and confirmations work

We ask contributors to share a photo they took and their own experience. Reviews go through automated checks. Flagged reviews can be assessed manually. Approval is not a guarantee that a photo is unedited or free of AI generation.

  • Email address confirmed means the link sent to that address was used. It does not prove a purchase or the identity of a person.
  • Company management confirmed relates to access to this company page. A paid plan does not verify individual reviews.
  • A review invitation does not independently prove a purchase. An order reference supplied by a company is not independent purchase verification either.
  • Publishing a photo with a review does not automatically permit reuse in marketing. A subscription does not grant that permission either.

Najeau positions itself in the premium haircare segment, targeting consumers who want a proactive, scalp-first approach rather than conventional shampoo-based routines. The brand's philosophy is rooted in ancestral Lebanese hair oiling traditions, updated with modern formulation science, and centers on supporting the scalp's microbiome and follicle health before water ever touches the scalp. Its key ingredient is cold-pressed extra virgin olive oil sourced from a 900-year-old monastery in the UNESCO-listed Qadisha Valley in Lebanon, harvested using regenerative, zero-waste practices. Najeau appeals to consumers seeking intentional, ingredient-led haircare with a clear heritage story and a complete treatment system that spans pre-wash, cleanse, and finishing steps.
