I recommend beauty accessories.

This is a scalp massage hair brush that I use frequently. I didn't really notice it when I was younger, but as I get older, I've become more worried about hair loss. I've bought and tried everything that's supposed to be good for it, but I think scalp massage is the most important thing, so I use it consistently every day. It feels a bit ticklish yet subtly refreshing, and my scalp doesn't hurt or get irritated. If you're worried about hair loss like me, I think it would be a good idea to buy and try this. It's best to massage your scalp after washing and caring for your hair. Of course, if the condition has progressed, it's best to go to the doctor, but using various accessories like this to prevent or manage it is very helpful, so please give it a try!
