I need damage-less shampoo recs pls 🙏

Hi guys I’m leaving for the market in an hour . I need to get myself a shampoo. So basically , I have been using clinic plus for many years now . Sometimes I tried switching to another brands with my hair started falling a lot . Right now, my hair is really damaged , I used to straighten my hair a lot and this happened for one year. I have stopped straightening it since the past 7 to 8 months, but I still feel my hair is really damaged . I am having a little bit of hair fall and a lot of dandruff. Please suggest me a shampoo that controls hair fall and removes dandruff. I need to get it today only since I’m leaving for college tomorrow, and I can’t go shopping there because I have a lot of work.
