5 Purple Shampoo Bars that will Instantly Tone Down Brassy Hair

Why Opt for a Purple Shampoo Bar?

Purple shampoos, regardless of their form, are designed to combat brassy tones in blonde and gray hair. Lately, more and more people have switched to shampoo bars as an alternative to traditional liquid shampoos. Here are a few reasons for that:

1. Environmentally friendly packaging

Switching to shampoo bars is a great option to reduce the use of plastic in your everyday life. Purple shampoo bars are an eco-friendly alternative to liquid purple shampoos that usually come in a plastic bottle.

By eliminating water manufacturers can offer more concentrated products. This results in smaller packaging, less plastic waste, and less carbon emission when the product is being transported. Shampoo bars usually come in a cardboard box or in a metal thin that later can be easily repurposed or recycled.

Purple shampoo bars are a way to keep the brassiness and yellowness away with a low environmental impact.

2. A little goes a long way

It is very likely to accidentally waste a liquid shampoo during its application. When using shampoo bars, unnecessary product waste is minimized.

Although they look small, shampoo bars last longer than standard liquid shampoos. A single bar can last you a couple of months. Just make sure to keep it dry between uses.

3. A Purple Shampoo Bar is an Ideal Travel Companion

Shampoo bars are compact and more convenient for travel than bulky shampoo bottles. A simple bar is small enough to take with you anywhere, saving considerably on space and weight when you are packing for your vacation trips. You also don’t have to worry about airport liquid limits or leaking bottles in your travel bag.

Metal thins they originally were packed in are perfect for storing when you travel. Make sure that the bar is dry before putting it in your suitcase, otherwise, it may melt.

4. Fewer chemicals

Liquid purple shampoos can contain harsh sulfate-based cleansers and other chemicals that can harm your color.

Shampoo bars contain fewer scary additives you can’t pronounce. Their formula with no added water eliminates the need for using synthetic preservatives.

By switching to shampoo bars, you will stop putting chemicals on your skin during your hair care routine. This can be a great benefit for people with sensitive scalps.

From Liquid to Solid Purple Shampoo: Tips for an Easier Transition

Be prepared to be on a little bit of a learning curve if this is the first time you use a shampoo bar. Your hair needs some time to adjust to the change in a product. They work better for thicker than for fine hair.

Wet the bar and your hair before shampooing. Rub the bar down the length of your hair in a combing motion. Repeat the motion a few times and continue to add water until good lather forms and thoroughly covers your hair. Then use your fingers to really work the lather around and to cover your entire head.

Another way is to rub the bar in your hands to build up a lather and then spread it over your wet hair and scalp. To make sure not to miss any spot, work the lather until you have a rich foam.

Keep the bar away from the shower to prevent mushiness. Use a soap saver to let the bar air dry between uses and extend its longevity.

When you are using a shampoo bar for the first time, it may leave your hair with an initial feeling of dryness. This might happen because shampoo bars don’t use wax and silicones to coat the strands. It can take a while for your scalp to adjust and start using its natural oil to moisturize and soften the hair.
