I want to be 100% clear here: the bottle pictured is for a new line to Redken's extensive products, CURVACEOUS, and the bottle pictured is for the already discontinued packaging. The product was introduced Winter of 2015 and repackaged by Spring 2016 (the bottles are now a grass green color). I am a licensed Cosmetologist, and I work in a Redken Salon (educated in a Redken franchise school "TSPA" so I am VERY familiar with every Redken product ever made). This line was developed specifically for people with wavy to curly hair, and it contains proteins, sugar crystals (to help curls reform into their natural shape), and Moranga oil (to provide deep moisture for dehydrated, porous curls). All Redken shampoos/conditioners are considered "treatment" shampoos and conditioners. I love this one for all hair types, even straight hair, because it is very concentrated (put a small amount in your hand then add water from the faucet!) so a small 8.5-10 oz bottle can outlast any gallon of cheap drugstore brand. I love this particular shampoo/conditioner line because it is amongst the lowest sulfate content (not a fan of the newest "high foam" formula for people who are convinced lather = clean) because it is the safest for color or otherwise chemically treated hair. Got a perm? Get curvaceous so it'll last and look its best! I LOVE LOVE LOVE this conditioner because it is extremely lightweight and designed to be used as a rinse out OR a leave-in! I find even in the salon, most people don't know this (even other Redken trained professionals like myself). So, for anyone with extremely dry, brittle, dull, damaged hair, especially those with a 3c-4c curl pattern, this conditioner can provide the best hydration, curl formation, and deep penetration of necessary proteins and oils to strengthen, improve, and add shine. This is a truly brilliant professional salon product, and Redken is amongst the most affordable of all professional salon products on the open market. LOVE IT!! (Be sure to look for it in salons ONLY as drugstores, supermarkets, and stores like Target or websites like O.co and Amazon are now carrying expired, discontinued, and even counterfeit products in violation of the contractual agreements these companies have to be sold ONLY by licensed professionals). Be sure to look for this with salons and other licensed professionals authorized to sell Redken products (Ulta Beauty is an excellent choice!) and look for it in the GREEN bottle, not this discontinued BLUE bottle. The styling/treatment products such as Rewind, Ringlet, and Full Swirl are all fantastic, too. Absolutely worth the money! In fact, when used correctly, you'll SAVE money over the water, sulfate, silicone, petroleum, alcohol, and filler infused junk you get at the drugstore that goes down the drain faster than your money and does nothing but leave your hair coated with petroleum and dimethicone giving the illusion your hair is softer and healthier when it's actually getting dryer and more damaged. REDKEN FTW!!!
