I have rather thick, wavy, hair that frizzes easily. I had my hair chemically straightened once, and it worked beautifully. Now my hair has grown out and chemical treatments are just too expensive here in the US. I have read the reviews for both SEDU/CHI straighteners online and both look amazing. Are they really as cracked up as they are said to be? And do they keep hair healthy even if used almost everyday? I used to straighten my hair with a regular CONAIR wal-mart straightener and it dried and damaged my hair. Also, is the SEDU/CHI straightener time effective as well? As in, under 20 minutes?

right now im leaning toward sedu. it has better reviews. let me know what you think.
