Liked the Air Styler. I have soft but frizzy curls so a 10 minute brush on damp hair made my hairs straighter (Please Note - Am not talking about Poker Straight which only Flat irons can give you!). Pretty much liked it as it makes my hair less frizzy and more straighter so I can keep them open without looking messy.
Girls with VERY curly hair should avoid it as the difference is not worth the price.
If you have a Wavyhair you are going to love it and best fussfree hair-dryer for all hair types... More detailed review here: http://curious-and-confused-me.blogspot.in/2015/03/philips-hp8658-essential-care-air.html
It definitely do not fry your hair like straighteners and do not feel as heavy as blow dryers. It is combination of two and this is what makes it perfect for every "other" day use. I have frizzy dry wavyhair then too I love it. Put it on second heat setting, and you'll get the straight hair not poker straight silky shiny as we see on advertisements but manageable hair for sure. If you're worried about heat that'll burn your hair. Well , keep this device moving and do not keep it near scalp. I use it with heat protect-ant sometimes and 5 inch away from the scalp. Because my waves start forming on lower ends and I do not want heat to mess with hair growth.
Go for it if you want a casual hair dryer with an attached comb..the comb is not dense enuf to hold ur hair tight as normal brushes does...so if u hav thin hair it is almost a lousy dryer...if u hav 'really' thick & dense hair then it is better as the comb will hold d hair lil tight..& d power is less (650W) compared to normal dryers (900+W)..so hair will have a naturally wavy look dan a straight look.. product looks really classy & elegant..
