I am worried about scalp and hairline troubles.

Lately, even though I'm using the same shampoo, I've been getting breakouts near my hairline.

I think the problem is probably that it wasn't washed properly, but if it's your face or skin, you could apply a blemish patch.

I thought using a trouble care product would work, but since it's for the scalp, it felt a bit tricky.

I have hair there, and breakouts appear right at the boundary between my scalp and facial skin.

How should I manage these ambiguous skin troubles?

I found scalp troubles especially difficult to manage.

The cause is unclear, and I don't know if it's irritation from the shampoo or due to oiliness.

I'm worried that using hair tonic or toner might make it richer.

I'm also worried that removing the oiliness through scaling might be too irritating.
