Is it safe to receive hair loss treatment after childbirth?

Exactly 100 days after giving birth, my hair started falling out like crazy, and it’s becoming unbearable. Every time I wash my hair, clumps of tangled hair come out onto my fingers, and looking at the floor while drying it just makes me sigh, so even vacuuming feels like a struggle. My hairline is thinning in patches, revealing my bare skin underneath, so I’m embarrassed to even go to the convenience store in front of my house without a hat. Everyone says it will naturally grow back over time, but I’m terrified that it might harden and leave those empty spots forever. Since breastfeeding is almost over, I’m looking into hospital treatments and heard that exosome injections are fast for scalp regeneration. I want to rush to the hospital right away because they say it directly stimulates the hair follicles, but I want to know if receiving it postpartum will help fine baby hairs grow back without irritating or straining the scalp, what the cost is per session, and what the recommended treatment frequency is.
