      Customers say this shampoo and conditioner duo delivers a luxurious rosemary scent and leaves hair feeling soft, clean, and lightweight without weighing it down. Many report improved hair strength, reduced breakage, and a refreshed scalp. The conditioner is praised for its rich formula that doesn't strip moisture. Common feedback highlights the elegant packaging and value of larger bottle sizes. However, some users experienced dryness, greasiness, or scalp sensitivity, particularly those with fine or curly hair types. A few noted packaging issues or changes in product formula over time.

        Best Shampoo for healthy hair!

        The smell, consistency of shampoo is amazing. I have fine hair but a lot of it which tends to get oily quickly, this shampoo helps in giving me shine and not drying out my hair.

        If you want the softest healthiest hair, this is the answer!

        It is always the best recommendation when your own hairstylist says "what are you doing to your hair!?" Mine did after I started to consistently using Necessaire. I ordered it a while back and love it but tried something else, and went back before I got through that product. NOTHING makes my hair feel as soft, calms the cowlicks, and fixes the frizz like Necessaire. I am a permanent customer!
