Botanical Skincare Researcher · Hadea

Lina Bayoumi is the lead botanical researcher at Hadea. She has spent over a decade studying plant-derived skincare actives, with a particular focus on Cyperus rotundus (nut grass) and the Middle Eastern and South Asian herbal traditions that have used it for hair and skin care for centuries.

Her work at Hadea centers on translating peer-reviewed research — including the 2014 Mohammed et al. trial on Cyperus rotundus oil and laser-resistant hair — into safe, effective, real-world formulations. She personally reviews every article published on hadea.shop for scientific accuracy.

Lina is not a medical doctor and Hadea content is educational, not medical advice. For diagnosis of conditions like PCOS or hirsutism, please see a licensed healthcare provider.

Editorial standards

Every Hadea article is researched against peer-reviewed sources, cites studies inline where applicable, and is reviewed by Lina before publication. We update articles when new research becomes available and show both the original publication date and the last updated date at the top of every post.
