All three claim to protect your hair from heat while leaving it soft & shiny.
Tresemme Heat Tamer Spray
I spray this in my hair before blow drying it then I spray a little bit before ironing it. I find that it does it's job at leaving my hair with a nice shine. The smell is nice. The only down side is I find that I can't spray this stuff anywhere near my roots are they'll be a greasy mess. Also I find that once I spray this in my hair and straighten it I have to wash it that night.
CHI iron guard
I've had this one for years & only managed to use half the bottle. This stuff leaves my hair greasy & kinda sniff, like hairspray would do. Overall I bought this when all the hype was going on about chi. I don't like it at all. I think it's overpriced and horrible quality. The smell is okay tho.
Got 2b guardian angel- gloss finish flat iron balm
I just bought this Friday & used it twice. I love the way it smells. Leaves my hair soft & touchable. Also adds a nice healthy shine to my hair. I find that it also helps prevent flyaway's & frizz. Overall this is my favorite heat protector.
