i have amazingly curly, frizzy, thick hair. i like to have it curly sometimes but i'd like to be able to make it straight. usually when i straighten it, it ends up really frizzy and some straight parts and some wavy and then curly parts in the back. what kind of straightener would work best, and what are some products i can use to take away the frizz and leave it shiney and completely straight?What are the best straighteners and products for very curly thick hair?
Use Biosilk on wet hair, then dry completely, then flat-iron with a CHI.What are the best straighteners and products for very curly thick hair?
get it japansese straitened at a hair salon. if you want it curly, then you can just use a curling iron.
Look up the Sedu brand straightener and read the reviews. I recommend the 1'; versus the 1.5'; because you can use it to better add some curl to the bottom if you want. It's durable and fantastic, heats up fast.. You'll see the rest. I love mine!
