Frizzy ends when straightening
I alternate wearing my hair naturally curly and then straighten every other time I wash (I wash twice week). I don't use shampoo and use 100% pure argon oil. However when I do the straightening with a blow dryer with round brush attachment the ends still get frizzy. I already cut off about an inch. Opinions if I should keep trimming the ends down - my hair weighs down better with more length, unfortunately, I would love a shorter cut but every time I cut it a few inches below my shoulders I get that "pyramid" look that is not pleasant.
