Review (2/5): Seems like quality has changed for the worse.
My toddler took a solid two years to get any hair worth brushing; we used this brush and loved it. It brushed her exceptionally fine hair very well and wasn't too rough.
We needed a second brush to take with us in our "car essentials" bag so I recently ordered it again. Something has changed between my original order and now; the density of the bristles is much thinner now. I'll upload a picture. I much prefer the older brush that I ordered September 12, 2020 (the brush in the right in the picture, labeled old) compared to the more sparse brush I ordered May 16, 2021 (left brush in picture, labeled new). Disappointing!
