Hair Botox

Hey y'all! I got a hair botox treatment in November of '25 and have noticed my ends have appeared a lot thinner. Photos 1 and 2 are a year before the treatment (Nov '24) and photos 3 and 4 are post (Feb/March '26) . For context, I was nursing during photos 1 and 2 and I regularly get trims every 12-15 weeks no changes in my routine/products and I typically do twist outs. I am wondering if anyone has experiencing similar breakage after this treatment and any advice (I don't plan to get the treatment again) going forward? Thank you!
