[Concern] Seborrheic dermatitis scalp hair loss precursor symptoms?

Hello, this is Sunja 🥲

 

Recently, I think I used the wrong shampoo, and my scalp has become extremely sensitive. Not only my scalp but also my face, I wondered if the perfume I received as a gift was the problem, but even when I didn't use the perfume, my condition didn't improve, so I thought about what had changed, and it turned out to be the shampoo.

 

One day, my scalp started to itch so badly. It was okay for a little while after washing and drying, but then it started again 😨

 

It was dried thoroughly, and I used cool air instead of hot air because hot air is not good, but there is no sign of improvement.

 

In fact, over the past few days, my hair has started to fall out significantly. When I wash my hair, the drain gets clogged, and even while drying after washing, hair falls out in clumps. When I brush my hair in the morning, it also falls out in clumps. I'm really worried that all my hair might fall out. First of all, I have severe scalp itching, and today, pimples started to form along my hairline. They are hard, red, and extremely painful to touch... So today, I bought a common over-the-counter medication called Nizoral.

 

 

I used the purchase for the first time today, but I'm still itchy and scratching.

 

It seems like my hair is falling out and new hair isn't growing back, and it's really thinning and sparse, but I'm still worried because it's falling out so much.

 

Concern (Question)

 

Does seborrheic dermatitis of the scalp sometimes progress to hair loss?

What kind of shampoo can be used daily for seborrheic dermatitis of the scalp?

Are there any others experiencing the same symptoms who have seen improvement? If so, what methods did you find effective?
