I have to admit this is the best i have done with a curling iron.
Edited to add: The hair i am wearing for my extensions is Janet Alco Remy Yaky. Very good hair, very little tangling and shedding. I have had it for i think a month now and i have washed it many times with no issues. Very costly, like 79.99 per pack for 14 inches but it is now my go-to hair for extensions. I am going to reuse and get another pack or an even fuller look.
