Before Kérastase came along, Davines Volu was my favorite shampoo for my thin hair. I was curious about it since Strategist beauty columnist Rio Viera-Newton (who also has fine hair) recommended it.

We put our hair through a lot—from hair dryers to curling irons to at-home dyes —all of which can cause hair to lose moisture, making it dry and prone to breakage, especially if you have fine hair.
