I second the Frida mom anything. They have a two step regimen with the comb and it cleared right up. You can also use breast milk if you’re breast feeding
And coconut oil. Light massages. My sons cradle cap is disappearing using both
Some baby or hair oils , Dr eddies happy cappy
We used the tubby Todd cradle cap stuff. It’s been helpful
With my oldest I just used regular baby shampoo and worked it in with a regular baby brush then combed through to get any loose flakes. took about 2-3 weeks to completely go away. With my baby she had cradle cap and dry scalp so I just used cooking olive oil and a regular baby brush to work it in let it sit about 10 minutes washed her hair with regular baby soap and used a brush to really work it in to get the olive oil out and combed through for any loose flakes. Both the cradle cap and her dry scalp were gone in 5 days
Frida baby oh crap cradle cap! Used it once and it cleared my daughter’s hair up!
