Hair Oils

This hot oil moisturizing treatment ($4; drugstore.com) opened up an entire market for hair oil products galore, but who can forget an old favorite? V05's original formula is here to stay!

The holy trinity of argan, camellia, and maize leave hair shinier and stronger ($54; kerastase-usa.com). Use it as a treatment and work a generous amount through hair before lathering up, or smooth one pump through dry strands to add extra shine.

The term "one-size-fits-all" rarely holds true when it comes to apparel, but this fresh-scented oil ($38; bumbleandbumble.com) is a different story. We love how it's lightweight enough for thin hair, but leaves thicker strands just as hydrated.

Gone are the days of heating up your treatment in a separate cup. This super-smart treatment ($36; sephora.com) warms to the perfect temperature in the shower, and turns back the clock on damage done by heat styling.

Curling irons and hair dryers are no match for this ultra-hydrating triple threat ($17 - $34; matrix.com for salons).

One drop is all you need to give your strands a healthy shine ($15; ulta.com).

Gourmet ingredients like avocado and mango sound good enough to eat, and leave your strands healthy and flyaway-free ($8; yestocarrots.com).

Now here's what we call a multi-tasker! This grape and hibiscus-infused formula ($48; nordstrom.com) can be used on your hair and body, delivering maximum hydration from head to toe.

Color-treated tresses take note: This sunflower and coconut oil-rich system ($29 - $50; pureology.com for salons) fills in any gaps left in the hair shaft by harsh dyes, leaving you with smoother, shinier hair, and a more vibrant hue.

We love how this argan and jojoba-infused line ($17-$21; mizani-usa.com for salons) permeates the hair shaft to provide intense hydration from the very first rinse.
