Joico has always been a favourite product of mine. This heat protectant smells amazing and it works wonderfully. I used it everyday for two weeks and my hair was less frizzy after blow drying. It’s definitely a product I would purchase.
Out of all the Joico Defy Damage products I liked this one the most. I used it when I was tanning at the beach and I felt like it protected my hair from the sun. Really good product if you’re out in the sun for the whole day.
•Protective Shield- I used this after washing my hair as a leave-in conditioner and heat protectant and it definitely did the job. My hair felt less frizzy and less dry for sure! This product also smells really good and doesn’t have a super greasy feeling that makes my hair weigh down!
