My parting on the crown of my head is thinning, so I'm asking about the cost of hair loss treatment.

I think it's because I've been under a lot of stress lately, but I've suddenly been losing handfuls of hair every time I wash it, and it makes my heart sink every day. As you can see in the photo, the scalp along my parting line at the crown of my head looks visibly white and bare; it looks lifeless and I feel like I'm going to get depressed. Topical scalp essences and supplements just aren't enough to handle it, so I'm seriously considering hair loss injection treatments that are said to soothe the scalp and strengthen hair roots. I've heard it's a long-term process and you need to go consistently for several months for fine baby hairs to grow in. Roughly how much should I budget for the treatment costs on a monthly basis? If anyone has any tips on whether paying for a package deal makes the cost a bit less burdensome, please share them! 🤗
