Protect Your Hair From Heat Damage!
It is very important to protect your hair from heat!
Blow dryers, flat irons and curling irons weaken and/or destroy vital proteins in your hair as well as deplete your hair’s natural oils.
Blow dry damage can be prevented by using products containing glycerin and propylene glycol because these actives retard water evaporation.
Iron damage can be reduced by using conditioners formulated with low molecular weight conditioners that can penetrate into the hair like cetrimonium chloride. Another study (see Reference 2) showed that exposing hair to heat in the presence of such a conditioning agent actually caused an increase in tensile strength (the force required to break a hair). This is because the heat reacts with the conditioning agents and cross links some of the protein chains inside the hair.
When Looking for thermal protector try finding a product with low alcohol content.
A few of my favorite protectors are by Pureology and Enjoy.

The best part is that these products aren’t just going to keep your hair from getting fried, but they are also going to add shine, de-frizz, help straighten your hair or enhance natural curls — depending on the style you’re going for. Once applied, you can heat style your hair with confidence.
