Hi Jane,
If you have to use a blow "fryer",then it being on cool is better.  Try using a moisturizing shampoo and conditioner,deep conditioner and oil your ends to see if all that helps.  TLC and a reduction in using that blow dryer should help.!   There is a wealth of info.. here so browse around and soak up the info.!!

Hi jane,

I feel your pain, I can't always get away with not having to use the dryer, either.  When I do (anymore) it's always on the cool setting, but sometimes I just have to for time's sake.  I find it to be less damaging than using the heat setting, difinitely, but I wish I could do without altogether.  I also find that if I protect my ends with a little jojoba oil, that is a big help, too.  Have you ever tried using any kind of oil?  It really is a saviour to hair that damages easily, like mine.

I use a blow dryer as well.  I use it on the low setting and also, I only dry it to the point where my hair is damp and then I  let it air dry from there.  That may work for you if you continue to blowdry. 

If you do decide to purchase an ion dryer, just know that in order to operate the ion function, the dryer (at least mine anyway) must be on the high heat setting, so that may not prove healthier for the hair.
