Mei

Mei covers scalp health, keratin-treated hair, and Asian hair care at QuestionOcean. Her work focuses on the side of straight hair that usually gets overlooked in mainstream coverage: oil management, damage visibility on thick strands, and the scalp-first routines common in East Asian haircare. She has thick, naturally black Type 1A-1B hair and has spent about five years researching keratin treatment chemistry, including the shift away from formaldehyde-based formulas. Her ingredient research background shapes most of her reviews, particularly in the K-beauty and scalp-serum categories. Based in Los Angeles, Mei also writes openly about hair thinning, a common concern in Asian hair that she believes is underdiscussed. Her approach blends traditional scalp-care practices with current clinical research.
