Okay, the user is asking about a two-year-old who cries and struggles during hair washing. Let me start by understanding why this happens. Toddlers often fear water in their eyes or ears, or maybe they had a bad experience before. The parent is probably stressed too, trying to get through bath time without tantrums.

First, I should consider the child's perspective. Water near the face can be scary. The parent might need strategies to make the child feel more in control. Like letting the child hold the showerhead or choosing when to tilt the head back. Also, using a soft washcloth or a tear-free shampoo could help. Maybe the water temperature is uncomfortable? Suggesting a check on that might be useful.

Then there's the emotional aspect. The child might associate hair washing with discomfort. Building trust is key. Maybe the parent can gradually introduce the steps, rewarding calm behavior. Turning it into a game or using a special toy could distract the child. Singing songs or telling stories might make it more fun.

I should also think about the parent's frustration. They need practical, easy-to-implement solutions. Breaking down the process into smaller steps—like first just wetting the hair a little, then next time more—could reduce resistance. Emphasizing patience and consistency is important because change won't happen overnight.

Another angle: the child's autonomy. Letting them choose the shampoo scent or a special towel gives them a sense of control. Maybe the parent is rushing, so reminding them to go slow and praise any cooperation, no matter how small, can build positive associations.

Also, checking the shampoo type. Baby shampoo is milder, but even then, some might irritate. Recommending a no-tears formula specifically designed for sensitive eyes could prevent the stinging sensation that causes fear.

Lastly, reassurance that this phase is normal and temporary. Parents might feel guilty or stressed, so validating their feelings and encouraging persistence with a positive outlook can help them stay consistent.
