I hate mousse. I have tried it so many times and just hate the way it feels on my hair. I always end up throwing it out. I diffuse every day too and have no heat damage. I use high heat and the medium speed and have no problems but it may be like Helloitsio said, the gel might protect. Also if you diffuse to about 80% dry instead of all the way it really cuts down on the time and helps with no heat damage. Helloitsio how do you like your Sedusa? I have read so many mixed reviews that I'm wary of buying it but my regular deep bowl diffuser isn't working so well now that my hair is so long.
