Unless you happen to have an atopic skin condition, psoriasis, etc. A bunch of the "shampoos" are combined with conditioner which means they're neither a good shampoo nor a conditioner. (Because those two are contradictory. Shampoo is to remove stuff from hair and skin, conditioner is to deposit.) It also happens that quite a few shampoos have a lot of aggressive alcohol or phenolic preservatives. Certain people are sensitive to these (most are not). Some "men" shampoos also have wrong pH, way too acidic, causing skin and hair problems in the long run. Some even with pH of < 3. (Properly should be between 3.5 and 5.5) And then there is the difference in strength of surfactant (SLS etc.) but that should affect just the dose. So yes, they're definitely all the same. /s The actual grift there is using weird oils, fruit additives which do nothing or just make the shampoo worse.
