Hello Mari, this is Kelly with Dyson. Thank you for your review. It can take some time to get used to the different settings, features and attachments Dyson supersonic provides during your drying session, not to mention your normal way or habit of drying your hair with traditional hair dryers. While everyone is different, we certainly wouldn't expect hair to become frizzy as a result of using Dyson Supersonic. The Dyson Supersonic hair dryer will feature intelligent heat control, which means it will monitor and control the temperature at all times. This helps prevent extreme heat damage and protects hair's natural shine. It also will feature negative ions to help prevent hair from becoming frizzy.

I'm happy to inform you that Dyson Supersonic hair dryers features 3 different attachments - a smoothing nozzle, styling concentrator, as well as a diffuser for use with achieving varying hair styles. Dyson Supersonic also features 4 precise heat control settings to also aid in drying, styling hair, as well as locking in your hair style. While the smoothing nozzle works well with working sections of your hair with a gentle airflow that can be used with just your hand, styling hair can be done with the styling concentrator as well as a brush.

With regard to the hair getting tangled, since the dryer does have intelligent heat control, it monitors and controls the temperature at all times. When the dryer is held away from your head the dryer reads the temperature of the room and not your hair; this also causes your hair to blow all around which can lead to damage and tangles. In light of this, it may be necessary to use the dryer directly against your hair with a low speed/heat setting (to start with) using either your hand, a paddle brush or roll brush to control the movement of your hair.
