This will be my very first review on MUA. After an exhaustive search for a flat iron spray/heat protector ( and lots of $$$ spent), I had almost given up and accepted my dry, damaged, highlighted hair. But something compelled me to check MUA once again and this time I BELIEVE I may just have found my HG product. AG Hair Care's "Firewall " spray is a miracle for me. I use it on my air dried hair as I'm flat ironing it. The most recent t time I used it, I first applied Matrix Moisture Cure Spray on my towel dried hair ( combed it through), then I applied some Garnier Fructis Sleek & Shine Smoothing Milk from mid length to ends, concentrating on some more damaged areas. Then, I twist it into curls and let it air dry. ( I have losely curly/wavy hair that is about 6 inches past my shoulders. Tends to frizz because of damage from coloring/highlighting). Then, when it's completely dry, I spray the ends of each section as I'm flat ironing it. And I must say ( with complete sincerety)that this is the ONLY one that has not made my hair stiff, oily, sticky, crunchy, dull or dry!! All I'm left with is silky, shiny & sleek hair that still feels like my hair !! If I could give this product more than 5 lippies, I definitely would!
