Laura McQuarrie — May 13, 2026 — Fashion
The skinification of haircare is changing the way consumers think about the health of their hair and scalp, and science-backed ingredients once reserved for facial products are now popping up in products like Biolage's new Hydra Source Moisture Method Serum. In this ultra-lightweight, water-based formula are hero skincare ingredients like fermented hyaluronic acid and micro-filtered aloe vera to provide immediate comfort and long-lasting hydration.
This moisturizing, no-rinse scalp serum can be used generously after cleansing, with Biolage recommending one drop for every inch of the scalp. Alternatively, it can be reapplied to a dry scalp or dry hair as needed.
Clinically tested to hydrate the scalp for 24 hours in one use, this instantly nourishing serum is vegan-friendly, paraben-free, silicone-free, and suitable for color-treated hair.
