ELLE editor review: “I’ve been using the Dr. Groot Hair Thickening Conditioner, along with the shampoo and scalp rinse, consistently for about a month now. I am absolutely obsessed with how healthy, soft, and strong it has made my strands feel! Plus, I’ve noticed dramatically less shedding since adding the brand to my routine. I just started my second bottle.”—Emma Aerin Becker, associate beauty commerce writer
