Depends On Your Hair--can Be Too Much Of A Good Thing
i'm growing out my hair (now past my shoulder) to donate to pantene lengths and needed a way to tame my hair without flat-ironing or japanese straightening which can damage hair. i have wavy asian hair and when let to dry after washing, twists and warps into all sorts of different unflattering waves.
my foray into pricy blow dryers came last month when i used my sister's $100 rusk speed freak. loved the results...fast and quiet. it left my blow out manageable, light with just the right amount of volume with minimal frizz. the best part was the blow out lasted into the second and third day (with a tiny bit of dry shampoo). at no point did my hair appear or feel oily (except for a little bit on the roots--that's where the dry shampoo comes in). i have never gotten sooooo many compliments in three days and thought well, if a $100 dryer works this well, something like the sedu 3600i would be even better.
the following week, after my purchase and a shampoo later i blew out my hair with the sedu the same way as i always have--round barrel brush and a tiny amount of chi silk infusion at the tips. it was very lightweight, easy to maneuver, and the buttons on the backside was great for not getting in the way but made it difficult to change settings quickly. also, the cool shot button was very awkward in that it's not raised from the handle. anyhow, the blow out was fast, easy and awesome! i did have the ionic button on the whole time and my hair was sleek, straight, shiny and felt not dried out. there was still some frizz up top from where some new growth was coming out. anyhow, at the end, i was in love! my hair felt silky, soft and looked like a commercial.
however, not 4 hours later, the ends started to curl again with my hair going limp and losing whatever body it had right after the blow dry (my other experiences with other blow dryers didn't have my hair go limp this quickly). then a few more hours after, my hair from root to tip felt and looked slick and oily. i don't know if it's the strong ionic output but it was odd. i blew out my hair again and the same happened another time. someone had suggested that i switch the ionic on and off but i thought for this price and what all goes into a blow out, i just didn't want to add another layer of complexity to the blow out like how much time and when and what temperature to change the ionic output.
other than that, it is an amazing blow dryer--just not for my hair after more than a few hours. i am planning on buying the rusk speed freak.
