I just started using protective shields and this is my favorite one so far I’ve used about 7 different kinds and this one works the best for the price range. I highly recommend using the entire Joico Defy Damange line for ALL hair types it’s incredible.
Protects my hair from all the heat products that i use and is easy to use with a pump. The creamy formula does not make my hair feel greasy and it does not weigh down my hair.
I got the chance to try the Joico Day Damage Protective Shield thanks to Chickadvisor! This spray in shield made my hair nice and smooth when heat styling it. I left it in when straightening and curling my hair and it left it smooth and frizz-free. Can’t wait to incorporate this into my usual heat styling routine!
