Their durability and longevity in travel containers also make shampoo bars an ideal environmentally conscious, plastic-bottle free choice for hair care while on the go.

Natural Ingredients

Made from natural ingredients like coconut oil and shea butter, ain’t shampoo bars pretty nifty for moisturizing and strengthening gray locks without any of those harsh detergents? Natural extracts of soothing aloe, nourishing avocado, and moisturizing glycerin, plus flower essences and herbal oils like rosemary and jojoba, give shampoo bars the power to cleanse gently while making hair softer and healthier.

Babassu oil, coconut oil, and purple pigments like lavender essential oil help neutralize yellow undertones while gently cleansing and moisturizing strands.

  2. Sodium lauroyl methyl isethionate
  3. Sodium methyl oleoyl taurate

Sulfate-free shampoo bars with moisturizing oils cleanse effectively while maintaining moisture balance. Slow graying and prevent brassiness with options free of synthetics. Focus on herbal, citric rinses for shine and color vibrancy.

Making the Switch to Shampoo Bars

Making the Switch to Shampoo Bars
Go for it and make the switch – you won’t regret leaving bottles behind! Here are 5 tips to help make the transition to shampoo bars smooth:

  1. Start with a small bar – They last much longer than bottles so you likely need less than you think.
  2. Get used to less lather – Bars make lush, creamy lather but it’s different from bottled shampoo.
  3. Focus shampoo at roots – Concentrate lather there then let it disperse through lengths.
  4. Give it time – Hair and scalp need a few weeks to adjust to the new formula.
  5. Store it dry – Let bars dry between uses to extend life.
