Jack59 Serenity Shampoo Bar — Vegan, Sulfate-Free for Sensitive Scalps

The Jack59 Serenity Shampoo Bar is a shampoo, pressed into a bar instead of bottled as a liquid. If your scalp gets itchy or your hair goes limp by afternoon, this bar cleanses gently while rice protein and panthenol work to strengthen and add shine. Bergamot, blood orange, patchouli and ylang-ylang essential oils turn a wash into something calming instead of just a chore, and spirulina powder colours the bar naturally, with nothing synthetic added. It's built for fine hair and sensitive skin — the jack59 serenity shampoo bar people search for when a regular bottle leaves their scalp tight or their strands flat.

Why Choose the Jack59 Serenity Shampoo Bar?

• Made for Sensitive Scalps: The formula is designed to calm an itchy, reactive scalp instead of aggravating it, using gentle surfactants rather than harsh sulfates.
• Strengthens Fine Hair: Hydrolyzed rice protein and DL panthenol work into the strand to add strength and shine without weighing fine hair down.
• One Bar, Fewer Bottles: A single bar replaces roughly 3 plastic shampoo bottles and lasts through 80+ washes, so the plastic never enters your bathroom to begin with.
• Cruelty-Free and Certified B-Corp: Jack59 is Leaping Bunny approved and Certified B-Corp — sustainability claims backed by an outside audit, not just a label.
• Naturally Coloured, Chemical-Free: Spirulina powder gives the bar its colour instead of a synthetic dye, keeping the ingredient list shorter and cleaner.

• Zero-waste beginners looking for a natural and organic shampoo swap that still performs
• Travellers who want a spill-proof, TSA-friendly bar instead of a liquid bottle

FAQs

What is the Jack59 Serenity shampoo bar made with?

It's a vegan bar built around sodium cocoyl isethionate and cocamidopropyl betaine for gentle cleansing, plus hydrolyzed rice protein and panthenol for strength and shine. It's scented with real bergamot, blood orange, patchouli and ylang-ylang oils and coloured with spirulina powder instead of synthetic dye.

Is the jack59 serenity shampoo bar good for sensitive or itchy scalps?

Yes — it was formulated specifically for sensitive skin and to relieve an itchy scalp, using gentler surfactants than many liquid shampoos. It also skips synthetic dyes and is gluten-free.

Will this shampoo bar work for fine hair, or will it weigh it down?

It's designed with fine hair in mind — rice protein and panthenol add strength and shine without the heavy buildup some conditioning bars leave behind.

How does a shampoo bar compare to a bottle of liquid shampoo?

One bar replaces roughly 3 plastic shampoo bottles and lasts through 80+ washes, so it works out to a similar cost per wash while keeping that plastic out of the bathroom entirely. Our guide to shampoo bars versus liquid shampoo breaks down the switch in more detail.

Is Jack59 Serenity Shampoo Bar cruelty-free and vegan?

Yes — Jack59 is Leaping Bunny approved and Certified B-Corp, and the Serenity bar contains no animal-derived ingredients. You'll find it alongside our other bars in the natural and organic shampoo collection.
