I don't know really but if you do get bangs of any kind or cut your hair it will get curlier than it already is. So be sure to take that into account.

dont do this...
it will be really hard to straight them everyday and if your hair are so curly and frizzy the straight may not last,so i suggest you no

For starters to keep your curly hair looking nice and less frizzy, I recommend this. I have it and it works pretty well when it comes to frizzy hair:



However, I don't know if going with side bangs is a safe decision.

Um I wouldn't do side bangs I guess because your hair even if straightened will blend in with the curly hair. If anything I would get regular bangs if you wanted bangs

Once you can put down the straightening tools and products, you can embrace who you are and work to get the best possible curly version of you.

I have long, thick, curly frizzy hair and I have bangs. Not hard to look after at all. I've always had bangs and didn't realise people thought so deeply about them.
You don't need all those products everyone's talking about. You just shampoo, condition, dry and straighten it. All those products are a waste of money.
