The 25 Beauty Launches of 2016 That You Should Have in Your Stash

The product: TRESemmé Beauty-Full Volume Pre-Wash Conditioner ($5)

Why you need it: It's not uncommon for fine-haired women to skip the conditioning step of their hair care routine in the name of volume. However, doing this will leave strands brittle. This formula from TRESemmé reverses the traditional cleansing routine: just use this lightweight conditioner before shampooing, then wash it away to see hydrated, thick hair.
