Firstly, find a new hairdresser as the advice you have had is rubbish!!!
Natural curl or wave is beautiful when the correct technique is applied. I would recommend that you buy (if you have not already got some) some of the latest magazines with curly hairstyles in. You could also look at the style gallery
on the site. ...More >
Here are some very important factors to remember with curly hair.
1. Adding layers into your hair can increase the volume and width of your hairstyle. Curly hair does not like this!
2. This impact’s on the styling routing and overall look of the finished style.
3. As there are many ways of technically cutting curly/wavy hair for a desired look, without actually seeing the amount of curl you have, it is difficult to recommend which technique should be used for best effect.
Weave cutting internal layers into curly/wavy hair place layers inside your style ( in the interior) and will not increase the volume or width as they open spaces within your hair cut to allow your curl/wave to fall more freely, looking more natural (Gloria Estefan).
Skimming internal layers into your internal shape with a blade or razor can increase or decrease curl depending what you want?
As I said above a good stylist SHOULD be able to advise what are your best options and give you something beautiful.
