Blow Out

This is my third blow out since I have been natural.  I did this one myself.  I used the tension method with the concentration attachment.  I forgot to measure my mane so I have no numbers to report right now.   Maybe I will blow it out again in another three months.  It took a good hour to blow this out and I did not like the blow dryer.  Actually, I didn't like the buttons.  The buttons are not compatible with slippery fingers.  So what do you think?
