Please do not buy this!
I bought this from Sally's yesterday, and will be taking this back TODAY.  I does not get hot.  Put on high, hoping for a 15-30minute deep condition, and 1 hour later.....?  Still TEPID!.  THis cap is HUGE, it comes down to my nose, can't read, can hardly see while peering out from under the cap.  Do not waste your money on this.  I am going to purchase this ThermalSpa Professional Heating Cap from Amazon (like I should have done last week), and keep on trucking.  After I deal with Sally's.
