I put product in my damp hair before I blow dry it. Normally my hair dries out easily when using heat tools but this product makes my hair so soft and smooth after I blow dry!

Rated 4 out of 5

I blow out or straighten just about every day and I really love this Protective Shield from Joico. It’s light weight and lightly secented – using it every day!

This leave in conditioner was my favourite product in the set. Scent was similar to the shampoo slight musky cologne hint. I use it every day and it really gives me that extra nourishment when styling my hair. Leaves my hair manageable instead of dried out and tangled as I have curly hair.
