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....

Works great
I have thin, fine, wavy hair and this stuff leaves my hair so soft and less frizzy without weighing it down. Definitely recommend.
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.
