“Jack of all trades; master of none”

Soap and conditioner have opposite and incompatible roles. Soap strips away dirt and oils. Conditioner replaces the oils stripped away by soap that your hair needs, to maintain health.

You don’t really need separate shampoo and body wash, you could wash your hair with standard bar soap. You do need separate conditioner.

Shampoo+conditioner combined together can either clean or apply oils to the hair, but chemically, it cannot do both, despite marketing.

3 in 1s are very water down. If all you want to do is remove grease from your hair and body, they are fine. You could use any generic men’s body wash for the same effect.

If you’re more concerned about your appearance and scent, them specialized products will give longer lasting and more noticable affect. Most people that use the all in ones don’t particularly care if their hair has that extra bounce, or it looks shiny for the rest of the day if not longer. And also, they probably don’t have longer hair that needs extra protection so brush or combs can glide through them and split ends are usually not an issue with shorter hair.

Various special products do more than all that even, but for most guys and some girls even with shorter hair, it’s not worth the extra hassle to apply them all when basically any form of soap will remove the excess oil and leave them smelling clean.

Well, If you’d like a woman’s perspective- it will do nothing but strip your skin and hair like extra strength laundry soap. Soap in general is really good at removing oil and dirt but it doesn’t distinguish. That is why conditioner is needed, to put back what the shampoo took out. Mixing them together make them both ineffective. As for soap, most body washes may make your skin soft, or have a certain scent - but you still have to wear lotion after. It’s the body wash’s conditioner so to speak. Shampoo can be modified to be less damaging, be safe for color, skin conditions or treat dandruff.

That’s why 3-1 is a gimmick. You don’t have to have 113 products. Just a shampoo, a conditioner, any soap at all and a good lotion.

I get 3 in 1 but only use it as face and bodywash. I have long hair that doesn’t play nice if I don’t use decent shampoo and conditioner. But the 3 in 1 stuff isn’t any more expensive than other bodywashes and there’s enough fuzz everywhere else that I like a little conditioner in my soap.

How else do you increase market share? Invent a need and product fill it

Scalp is skin so any wash that’s safe for one is okay for the other. Hair is a different beast entirely. The ends of long hair are much older than the cells on your skin, and they need moisture plus detangling. However if you have very short hair the damage done by using a cheap 3 in 1 product will be cut off before it becomes noticeable.

Go ahead and try a few 3 in one, see if you like any. But I would suggest diluted apple cider vinegar for hair, and biodegradable soap for the body, that’s as simple as I’ve been able to get it.

They’re mediocre products only used by men who don’t give a fuck and suicidal women (I’m the former sometimes). If you have long hair, for instance, the “shampoo part” of this magic liquid will barely wash anything.
