Why did I make the switch from Pantene, Garnier, Suave, etc to Solid Shampoo? The real question is Why didn't I make the switch sooner!
Solid Shampoo can have tons of benefits, if you look carefully you can find brands that are vegan, cruelty-free, and chemical-free. The most common and toxic chemical in shampoo is the sulfate, and many organic shampoo bars don't contain this.
Another reason why shampoo bars are great is the travel-ability. A small block can last months, and doesn't break TSA's liquid travel rule. No more exploding or leaking tiny hotel shampoo bottles all over your suitcase. And with that, there's no need to carry a giant bottle around while backpacking or travelling- a small, lightweight block is all you need.
Things to Consider:
Shampoo bars need time to dry, and a container. If you leave moist bars in their container and close the lid they will get soggy and run out quicker- and it can be a pain to get all the gunk out of the bottom. Therefore, after each use I leave my shampoo bar on top of the tin for a few minutes (be careful no one uses mistakes it as soap or showers with it out in the open) . In you can leave it out to dry on your bunk.
Most people take time to transition, many people are turned off by the idea that your hair might be nasty for a few days or even weeks while starting solid shampoo. This is natural. Regular shampoos contain chemicals that strip your hair of natural oils, causing your scalp to over-produce the oils. This means more greasy hair for you, and more showers, and more spending money on shampoo. Some people also get a "waxy coating" on their hair from certain solid shampoos, but many times this just means you haven't adjusted or you are using the wrong type of bar for your hair. I didn't have any trouble transitioning to solid shampoo, but I did a lot of research to try and avoid the "greasy stage."
