        This is great shampoo & conditioner. Invigorates the scalp, smells great, makes hair soft. I like the larger bottle size. I also have the rosemay hair oil, which absorbs very easily & doesn't give me greasy hair like orher oils I've used.

        From the high quality ingredients, to the way it smells beautifully, and the way my hair curls unlike ever before, this shampoo & conditioner set is truly the best. If you go through the ingredient list and compare with competitor brands, Necessaire does not contain the chemicals that harm your hair over time. They use a repairative and thoughtful formula. Even making it rosemary-based has extreme benefits for hair in itself. I absolutely love Necessaire and I am very pleased with their hair line.
