NOUNOU Nourishment + OI Oil for Rejuvenation Set

Yes, they complement each other perfectly. NOUNOU restores the health and structure of dry, processed, or brittle hair through deep nourishment at the wash and condition steps. OI Oil is the finishing step that adds the reflective shine, frizz control, and heat protection that make the restored hair look luminous and rejuvenated rather than simply conditioned. Nourishment repairs how the hair feels; the OI Oil finish transforms how it looks. Together they deliver both health and radiance.

No, not as a first choice — NOUNOU is a rich nourishing system best suited to medium, thick, or coarse hair that is dry or processed. On fine hair it can feel heavy. If your hair is fine and dry, the Davines MOMO moisture system is a lighter fit. That said, fine hair with significant chemical damage may benefit from NOUNOU used carefully (conditioner on ends only), and the OI Oil should always be kept to the ends on fine hair to avoid weight.

Yes, technique matters. Warm 2–3 drops between your palms for about five seconds first — this emulsifies the oil so it spreads evenly across the hair with just a small amount, rather than landing in a concentrated patch. Press it through damp or dry mid-lengths and ends, keeping it off the roots. On damp hair before blow-drying it adds heat protection and a smooth finish; on dry hair after styling it adds pure shine. Start with less than you think you need and build only if the ends need more.

Yes — colour-treated hair is often dry and processed, which is exactly what the NOUNOU system is formulated for. The deep nourishment restores softness and strength to hair depleted by colour or lightening services, and the OI Oil's antioxidant Roucou Oil adds shine while providing some protection against the oxidative stress that fades colour. Both products are colour-safe. For colour-treated hair where tone maintenance is also a priority, the MINU colour-care system can be added to the routine.

No other Davines system targets processed and brittle hair quite the same way. NOUNOU is Davines' most intensive nourishment family, specifically formulated for hair that is chemically treated, bleached, or naturally dry and depleted — it prioritises deep nourishment and restoration of softness and strength. MOMO, by contrast, is a lighter moisture system for dehydrated but healthier hair, and MELU targets mechanical breakage. NOUNOU is the right choice when the hair is genuinely processed, rough, or brittle and needs rich, restorative nourishment.
