I used the hairbrush myself first, I was on the phone with my sister and as I was brushing.... goosebumps started from my scalp, to my cheeks... in a wave all the way to my very toes!! Not a snag, the happy hairbrush not only massaged and cupped my scalp, but it gently (magically) parted my knots in my fine hair! My 6 year old daughter - Dolly was ASTONISHED! She even played ‘hairdressers’ with her little friend... Dolly actually fell asleep cuddling her HAPPY HAIRBRUSH... No more battles, screaming or painful grooming of my girls fine, long wavy hair. X thank you
