When I first started buying this serum, I had intended to use for it's heat protecting properties. What has made me stay almost unfaltering in my love for it since then, however, is how well it helps to tame frizz. I have very thick hair, that sits somewhere between straight and wavy. For as long as I can remember, I have had problems with frizz, especially after blow drying. Over the years I have spent a fortune on products to try to avoid the fuzz, but most did little, or only weighed my hair down, making it look and feel oily. The John Freida Frizz-Ease Thermal Protection Serum is the only serum I have come across that truly works, while still being light weight and non-greasy.
This lightly oily textured serum is a great little multi-tasker. It can be used to protect against heat, prevent and smooth frizz, and add shine. It works just as well used on wet or dry hair, and before or after styling. I have tried it each and every which way, and it works well regardless. I find it works best for my needs as a finishing product, once my hair is styled and dried. I simply rub a 5c piece size squirt between my hands well, and work it from the ends up.
After using it, my hair feels like silk and has a whole heap more shine to it. Most importantly, though, my hair is instantly more sleek, without losing any movement or volume.
I will say, that although this product adds shine and makes hair feel healthier and more moisturised, it does not do a lot to add or retain moisture in the the hair. If you suffer from frizz too, you may have a similar issue to myself in that the mid-lengths and ends of the hair can be very dry. To prevent and lessen future frizz, I would recommend using a light leave-in conditioner, or moisturising hair oil (I use argan oil) on towel dried hair, especially if you are going to be heat styling. It also should go without saying that if you use this after styling, you will need to use another heat protecting product before you use any kind of heat.
