This has been a miracle
This has been a miracle for my hair. My hair was so dry and brittle with breakage. My hair stylist used it on me at the salon and suggested it for continued use. When I returned in 28 days she was jaw dropping amazed at the difference of softness, strength and no breakage. Softness you can feel to the touch and see the beautiful shine. I wash my hair every 3 days.

A must buy for bonding and softening ends of hair
Thos product is amazing! I color my hair every 6wks so lots of breakage and dryness 2. Washed with Joico youth shampoo n then same conditioner. After, I rinsed and applied this product to mainly ends of hair. Flipped it over and used nozzle to apply super small amount. Combed it thru from ab midsection to ends (avoid roots or will b too soft to style). Waited 7secs rinsed thoroughly. Blow dry and styled..my hair looked like it did when I was in my 20's. Shiny, bouncy, no weigh down. It truly floored me!!! I've used it everyday since I received and after every wash Im just as impressed. Highly recommend and will buy again. ****Lil note..follow instructions exactly and stay away from roots (unless u r doing a sleek backed up do. It will be too soft to do nething else if u do roots.

So impressed!
Wow, this stuff really exceeded my expectations. I feel like my hair is weak (lots of hair, but the individual strands are very thin) - I have highlighted my hair for years and always wind up with a lot of damage and frizziness at the ends. I order a million different expensive hair products, hoping each one will make a difference but I'm never usually impressed and they never seem to do much. This product made such a difference! And it was so fast and easy. I have countless products that need to be left in for 5, 10, 15 minutes and those are a pain. This took literally 7 seconds and when I got out of the shower to dry my hair, it was so smooth and frizz-free. It really seemed to bond my ends. Great product and I'm so impressed!

Stuff was good. I've used better. Hard just getting in ends to make suds.

Such a great product!
This stuff works wonders! I bring it with me to my hair salon and whoever is doing my blowout is so impressed with it. It makes your hair feel so soft and smooth and it smells wonderful too. I don’t get paid to write reviews, but when I buy a product that I think people should know about I write a review because I always read the reviews and I hope they are honest. Definitely buy this product for softer, smoother and overall better hair. I’m thinking of trying the shampoo and conditioner too, since this works so well.

Joico is the best Co
My hair looks and feels healthier. I use it once a week and I don’t have as many split ends. Smells really nice.

Not as described
After i put it it was easy to comb thru and detangle but once the hair dried, all frizzy and dry and definately not as good as using a conditionner.

Calms tangles and much more
My hairdresser recommended this product and it IS all that it says it is. This helps to calm the frizzies and the tangles in my wet hair. Hair that is prone to be dry nowadays, and fragile. This is my go-to product and I'll be trying others of this brand. It doesn't take much and is cost effective, no heavy scent, brings softness and shine also. I've had this one bottle four 4 months now, and it's still halfway full. Thanks for a great product!
