Redken positions Oil For All as a universal styling oil for all hair types and textures, including colour-treated hair, rather than one aimed at a specific texture like curly or coarse hair. It suits anyone who wants a lightweight pre-styling or finishing oil for shine and frizz control without extra weight — useful for finer hair that gets weighed down by heavier oils, as well as thicker or coarser hair that wants added slip and smoothing. It's a retail-facing product suited to everyday at-home use, not a professional-only or clinical formula.

The main case for Oil For All over a more specialised oil is convenience and consistency — it's designed to work the same way across hair types and to do double duty as both a heat-protecting prep product and a shine-finishing product, which simplifies a routine that might otherwise call for separate items for each step.

• Apply to damp hair before styling, concentrating on mid-lengths and ends.
• Style/blow-dry as usual; the product is formulated to also help reduce blow-dry time.
• Can also be applied to dry hair afterward, in small amounts, for added shine and to help lock in moisture and control frizz.

• Pro: Works across hair types and textures as a single product, rather than needing a different oil per hair type.
• Pro: Doubles as a pre-heat-styling protectant and a post-styling shine finisher, so one bottle covers two steps.
• Con: Because its performance depends on silicones, it isn't the right pick for anyone specifically avoiding silicone-based haircare (for example, some curly-hair routines that avoid buildup-prone silicones).
• Con: As with most silicone oils, it can contribute to gradual product buildup on hair that isn't regularly clarified.
