I have naturally VERY curly hair and hate it!  That is why I always straighten my hair with a flat iron after it is washed.  Because of this, my hair has years of damage (including split ends and breakage).  Since I have been using this product my hair seems to have Strengthened.  I really did not expect to notice any difference but I do not have as many split ends as I used to.  I am planning to use this product until I fully understand if it is helping my hair.  At this point I believe my hair is stronger, but I am not sure.  I like the fact that Dove has a conditioner exactly like this...
