Washing hair

Hair washing is becoming a total nightmare with Sarah, was 2 in September.

Does anyone use the hair shield thing? Where can i find it? Does it work?

I've tried the jug thing, but she doesnt understand to put her head back.

I let her choose her own shampoo this week. she wants to use the shampoo to wash her body, and pleads with me: "No washing hair, Mommy, PLEASSSSSE!"

I've let her wash my hair and shown her there is no reason to get worked up. Nothing has worked.

As a result I try to do it as quick as possible and get it over with.
