Nah that's just what Maybelline want you to think, and you do think it, so they have won.
I haven't used shampoo on my long hair that is mid back length now. It's not at all greasy. It was for a month when I had short hair and gave up on shampoo.
Also I no longer have dandruff and my hair is more manageable, so I don't need product in my hair either.
I "shampoo" with conditioner once a week and just use hot water the rest of the time.
That sounds disgusting no matter how many times you want to say it's actually not that bad. I will fall for big Shampoo propaganda because I don't want to feel extremely gross. That's why I get my advice from people irl with healthy hair. I also suggest telling this to your barber next time you get a haircut.
Sure. I would have agreed before I knew better. To think you know better without experience though is pure ignorance. You can ignore people wit experience and keep listening to marketing all you want though. Whatever.
Also, my barbers always comment on how healthy my hair is and ask how I do it, and it takes very little effort to do (negative effort considering I'm removing something else).
Nah you don't, I didn't use it for a long time and my hair was great! There's a period after you stop where your hair is greasy, yes, but after ~a month it settles down a lot. You still need to wash it with hot water but, if anything, in my experience it was more resilient to missing a day of washing than it is now that I'm using shampoo/conditioner again.
Edit: I should say though this is probably not for everyone. Depends on your hair type and how healthy your scalp is.
