Making your own DIY shampoo bars has beauty, health, environmental and financial benefits convincing enough to stop you from ever buying drugstore shampoo again. 

Firstly, DIY shampoo bars are the best way to avoid using harsh chemicals in your hair and on your scalp. Making them means you can choose all-natural ingredients that are both kind to your hair and the planet. Plus, you can tailor your DIY shampoo bar to suit your hair care needs exactly. 

Shampoo bars are also a much more sustainable hair care option than drugstore shampoos. The plastic packaging of normal shampoo ends up as single-use plastic waste, contributing to around 550 million empty shampoo bottles in American landfills every year. Homemade shampoo takes out the need for plastic packaging, therefore significantly reducing plastic pollution. 

If these benefits are not convincing enough, consider that they’re also a huge money-saver. Making your own shampoo bars at home, using natural ingredients you probably already have at home, is going to massively reduce the cost of your monthly drugstore shop. 

Follow these DIY shampoo bar recipes for how you can sustainably keep your hair clean and healthy.
