Rated 5 out of 5 by from SPIRULINA PROTEIN I love this heat protected. It’s Lightweight. Perfect for dry hair leaves. No residue. Smells amazing. It doesn’t make your hair. Feel sticky since it’s super weight.

Rated 4 out of 5 by from Versatile with an out of this world scent This is a versatile heat protectant! It is great to spray on damp hair for a frizz- free, long lasting blowout or on dry hair for smooth and luminous thermal styling. The sweet woody scent is an added bonus of you are a fragrance fanatic like me. It sits between a warm sweet vanilla gourmand perfume and a smoky cedar cologne.

Rated 5 out of 5 by from BEST HEAT PROTECTANT This is one of my favorite heat protectants! I love that it’s an aerosol spray because it evenly coats the hair! I also love the biggest size bottle they have it last me forever! I recommend this to all my clients because most people are only using a spray directly after the shower but not before extra heat styling!

Rated 5 out of 5 by from My favorite styling product! I'm obsessed with this product and my clients are obsessed with this product. I keep this at my station and on set. I love that the product can be used on both wet and dry hair and it works with all hair types. It makes the hair soft and helps with frizz and everyone always compliments on how great it smells. Definitely it must have especially if you style hair with irons often.
