8 Best Conditioners for Thinning Hair 2026, Tested and Reviewed

This plant-based conditioner swaps out water for aloe vera, a more nutrient-rich base that delivers hydration and scalp-soothing benefits. The thin texture spreads easily, moisturises well, and won’t weigh down fine strands. It also includes a blend of botanical oils – like argan, olive, and pumpkin seed – to support smoother, stronger hair. Our tester was impressed by how lightweight it felt, how much stronger her hair became postpartum, and the way it left her strands feeling healthier overall.

Our tester says: “I was pleasantly surprised by this conditioner!” says Glamour tester Shannon Browder, who tested the sister shampoo as well. “While it has a thin consistency – which made me skeptical at first – it spreads easily and doesn’t weigh my hair down. The scent is absolutely delightful, like a fresh coconut mocktail that makes every wash feel a bit luxurious. I’ve noticed a significant reduction in hair thinning after a few weeks of use, which is a huge win postpartum. My hair feels stronger and healthier overall. Highly recommend for anyone looking for a lightweight yet effective conditioner.”

4. Best Budget: Monday Haircare Thinning Conditioner

Monday Haircare Volume Conditioner

• What we love: Hydrates dry strands; very affordable.
• What could improve: May not reduce shedding on its own.

This sub-£10 conditioner proves you don’t need to splurge to start addressing thinning hair. It’s an easy entry point if you’re unsure where to begin: The lightweight formula rinses clean, adds subtle volume, and leaves hair feeling softer and healthier without a big investment. While it may not dramatically reduce shedding on its own, our tester found that the drugstore product noticeably improved softness, bounce, and manageability, with a scent she couldn’t get enough of.

Our tester says: “Since incorporating this conditioner into my hair-wash routine twice a week, my hair has felt significantly more hydrated and healthy, even for days after washing,” says Glamour tester Bailey Gann, who has thick, dry hair. “The formula is easy to rinse out (no heavy residue!), yet still leaves my hair feeling soft and smooth — not to mention the smell is incredible (do they make this in a body wash?). I didn’t notice a major change in shedding, but the boost in volume and overall hair health made me want to wear my natural hair down more often instead of keeping it up or slicked back.”
