YOU NEED THIS IF YOUR HAIR IS DRY OR DAMAGED
I first bought the trial size line as it gives you the shampoo, conditioner, hair masque and heat shield. I was still able to use my leave-in conditioner before applying the heat shield, so I was happy about that! With the shampoo, a little goes a long way, even for long hair (yay!). You have to u...

No rated heat protection, zero transparency from Joico
I liked the way this product made my hair feel, but was interested why there was no set temperature in the description as to what this product protects to. I had to ask the question three different ways to get an actual response out of Joico, who purposely tip toed or tried to redirect their answer....

WOW!!
I have never noticed a product working so visibally well! I got this for my mom who has been dying her hair for decades and has always had very frizzy and dry looking hair. I gor this for her as a gift and gasped when i saw her again. Her hair is shiny as if she just went to the salon. Theres no friz even in the 85 degree summer heat with high humidity!! I rarely leave prodcur reviews but had to share this holy grail. Plus- its much cheaper than many other brands. When my Bumble and Bumble runs our Ill be purchasing one for myself!
Excellent leave-in treatment
Hair Type Wavy Hair
I love this leave-in. I love it so much, I gift it to all my friends and family, and now many of them are hooked. Leaves great softness and shine.
The only thing that helps
I have coarse hair wirh a bleached blonde money piece, and a cowlick that doesnt cooperate with air drying. This is the only thing that makes it manageable! It provides softess and shine with added heat protection against the styling tools i need to make sure my hair isn't sticking straight up, without making it feel weighed down the next day. I tried different brands and different products and this is the holy grail.

Absolutely love it, stocking up....
I have naturally curly, thin, brittle, frizzy, high porosity hair. Even a little humidity when it's straightened completely ruins my style. With this, I can go for a hot, sweaty bike ride or long run, and my hair remains straight and frizz free. I know some complain it's too heavy for their hair, causing it to appear greasy, my hair NEEDS it to be heavy to work. So few things do...please, for the love of all that is holy, DO NOT DISCONTINUE THIS!! HG product for me. The search is finally over. Can't wait to have to option to wear my hair straight, or curly, this summer.
