Men shampoo >> women shampoo

I recently saw a insta reel about a girl using her bf based brand shampoo for men and her hair got super long and dense and she said girls are getting scammed? Is that true? I see these type of stuff everywhere where mens stuffs are always better. If that's true why we all not just raid them? I now to want to try some of men stuffs to know whether it's true or not, so girlies and guys if u have any recommendations for clothes, hair or skincare that men uses plz tell me the product to buy! Especially hair products! ヾ(☆▽☆)
