DD (12) has bum length wavy-ish hair that can frizz/knot easily. It will blow dry nicely but then that effect wears off. She had it straightened at the hairdressers once and it looked good for days. I don’t want to buy straighteners and encourage that as she is still young and I know they are terrible for hair. I also think she would burn herself 😆 I am wondering if a hot paddle type brush would work well, not for daily use but on the days she wants to smooth her hair a bit. Looking at GHD glide or similar? Any recommendations?
