I used this when my baby had craddle cap and after a few uses maybe 3-4 times all the craddle cap went away!

I feel like it was a little too much for my LO's head, she was quite upset the two times I used it. Then my toddler got ahold of the brush and tore the foam off very easily

To be clear, this doesn't treat or prevent cradle cap. It's useful to remove the scaly bits on your baby's scalp once they're ready to start falling off. We found the lice comb looking tool to be the only one that does anything. We like to wet our baby's hair at the beginning of bath time and by the time the bath is over, you can gently brush the thin comb on your baby's scalp and it'll loosen any scales that are ready to fall off.

I'd give it a 5/5 if they just sold the comb by itself.

My baby's cradle cap was gone by the third bath. :-)

My sons cradle cap was very severe, it covered his whole scalp and extended down his face to his eyebrows. It broke my heart seeing him so uncomfortable, it was itchy I’m sure! We tried all the home remedies, but nothing seemed to improve. I ordered this comb and used it with a doctor recommended shampoo (Nizoral). After the first use, nearly all of the thick, crusty scales had come off his scalp, and his face was totally clear. I couldn’t believe it! After 2 uses, it was 100% gone. We keep his head moisturized throughout the day with a little bit of coconut oil. You would never know now just how bad it was after just a few days. This brush it amazing!
