Most gentle shampoo?

Si

My son has a hemangioma (strawberry) on his head and it’s beginning to look dried out, my question is, what is the most gentle baby shampoo you moms have found?

I currently use baby bum on him and he does amazing with it, but I’d like to prevent his strawberry from drying up more. Thanks in advance!

Picture of it attached to show what it looks like.

1- doctor said the size was normal due to it being on his head, it’s just more prominent due to its location.

2- dark spots are where it is no longer getting blood flow because it’s starting to go away.

3- it’s NOT an infection, I posted asking about it on a group I’m in on Facebook and people assumed it was an infection, it’s not. He’s been seen for it both by his doctor and triage nurses. He has a dermatologist appointment this month too!

And yes, he’s had it since birth😩
