Is it possible to care for the scalp at home?

Hello, I used to blog, so I used to get regular head spas through sponsorship. But now that I've been blogging less, I've naturally stopped getting head spas, and I think my scalp has gotten a lot more dead skin cells.

Are there any home scalp care methods? I'm concerned about dead skin cells, and my hair is thin and weak. If anyone is already practicing scalp care at home, please recommend any good methods or products.

I, too, want to regain my healthy scalp and hair through scalp home care. Facial skin is important, but the scalp is also part of the body. A healthy scalp will lift my face and improve my complexion, so I want to focus on that!
