Now this tip is not for everyone. But I’m a hippie tightarse and shampoo bars are now up to $15 or much more.
When staying somewhere for a short time I used to throw a bar of the sensitive version in my backpack as a spill proof 2 in 1.
As Dove is a non-soap detergent bar it’s milder and has a ph closer to neutral (unlike soap/soap based shampoo bars) so isn’t really damaging. Other syndet bars may work as well.
They’re very cheap and harder to waste than liquid. The individually sold bars are plastic free packaging. And while a little too drying on my face and a little too gentle for my body, in a pinch they very much can be multipurpose.
If you’re already confident with using shampoo bars give it a go.
Disclaimers
I wouldn’t advise it for anyone with dry hair or scalp issues that could be exacerbated. I switch between this and silicone free liquid shampoos so no idea if exclusive use causes long term problems.
Also - if you’ve been using shampoo or products containing ‘cones and change to any shampoo or cleanser that doesn’t contain them, your hair will be rough and crappy for a while because the shiny waterproof coating is being removed to show the damage and dryness it caused underneath.
Be careful of soap based bars. They’re advanced territory or just plain bad.
There’s also a particular way to wash hair with bars so if you’re unfamiliar look into it. Piling your hair up on your head and scrubbing suds into the lengths causes dry stripped hair and tangles with anything you use so please don’t just do that.
Wet your hair and the bar, rub the bar in your hands and press/wipe the little bit that comes off onto your scalp in sections. Back, front, sides, crown. Reloading your hands for each.
Lather well into your roots with fingertips and let the suds rinse out through your lengths to gently clean them. Make sure you rinse very thoroughly. Repeat if needed.
