This gentle conditioning and detangling formula works to smooth and tame unruly and frizzy hair. Moroccanoil's AminoRenew Smoothing Conditioner, featuring a proprietary ingredient, restores depleted amino acids to strengthen and align hair's natural keratin structure. Suitable for women, the formula instantly nourishes strands with antioxidant argan oil and argan butter, leaving you with healthy-looking, calm, manageable, and smooth hair. When used with Moroccanoil AminoRenew Smoothing Shampoo, results can last up to 72 hours. For best results, use after shampooing, gently squeeze excess water, and apply from mid-length to ends. Leave on for 1–2 minutes and rinse well.
