Reviews
I perm my hair and sometimes leave my hair to grow for too long before cutting it so I have a lot of dead ends. This product is great for protecting my hair and making it seem healthier. The only thing I don’t like is the application – I prefer sprays so I don’t have to get my hands dirty. I got this product as a deluxe sample for free in exchange for an honest review.
Price: 30-35 cad
Cruelty Free: nope :/
TLDR: Great but it’s gotta strong scent.
I received these products from chickadvisor for free.
Packaging:
Very Cute I really love the look of Joico products it always makes you feel like you are getting salon stuff. Also these mini bottles were not difficult to use the entire amount of products (often they are too hard and then you loose a lot. Purple + silver = awesome
Product:
This product is awesome. I tried it alone and with the other products. Its a difficult one to tell if it’s working short term but I will say my hair didn’t get any new damage from blow dryers or heat tools that I could see. I would say this and the mask together would be your ultimate tools from joico. I would also say again if you are scent sensitive this is not a product you should use. All of them have very strong perfume scents.

I am happy with the product. Absolutely worth trying it and love scent every-time. Smells fresh flower. See result right after using it. Really works good on my hair. Great time using it during the long weekend. Prevent damage on my hair. Will recommend it. Good price.
