This oil is aimed at color-treated, heat-styled, or frizz-prone hair that wants extra shine and a smoother finish from a quick, pre- or post-styling step. It's simple enough for a styling-product beginner to use correctly. One caution worth noting directly from It's a 10: because the formula is keratin-based, hair that's already fragile or heavily bleached can become more prone to snapping if keratin-based products like this one are overused, so it's not the best pick for that specific hair condition.

What distinguishes this from a straightforward plant-oil hair serum is that it's designed to work at two points in a styling routine, worked through towel-dried hair before heat styling for some thermal glide, or smoothed over dry hair afterward to knock down frizz and add shine, so one product covers both the prep and the finishing step instead of needing a separate serum for each.

Work a small amount through clean, towel-dried hair, then air-dry or heat style as usual.

Or, on dry hair: rub a small amount between your palms, smooth evenly through strands, then glide lightly over hair after styling for a sleek finish. Follow with a soft-bristled brush if desired.

The silicone-heavy base is what gives this oil its slip and shine without a greasy after-feel, and layering keratin and several plant oils on top of that base adds some real conditioning benefit while you style, whether that's before heat styling on damp hair or smoothing flyaways on dry hair afterward. The trade-offs are the flip side of the same formula: it leans on parabens for preservation, it's built primarily on silicones rather than plant oils despite the "oil" name, and It's a 10's own guidance warns against overusing it on fragile or heavily bleached hair.
