Some people notice a short adjustment as the scalp rebalances after years of synthetic shampoo — usually a week or two. Most feel the difference from the very first wash. If your hair has heavy silicone build-up, a single clarifying rinse beforehand smooths the switch.

All of them — straight, wavy, curly, coily, fine or thick, color-treated or natural. Shikakai has been used across every hair type for 4,500 years. It's gentle enough for daily use and effective enough for build-up-prone scalps.

Most shampoo bars are just solid versions of regular shampoo — same synthetic surfactants, pressed into a puck. Hikakai uses zero surfactants. It cleans with natural plant saponins, so it never strips your scalp or triggers the grease cycle that makes you wash more.

60–90 washes per bar — roughly 3 months for most people washing a few times a week. That works out to a fraction of the cost-per-wash of bottled shampoo, with none of the plastic.

Warm, earthy and natural — no synthetic fragrance. A subtle herbal scent from the Ayurvedic botanicals that fades clean after rinsing, leaving no artificial perfume behind.

Every order is backed by our 30-Day Money-Back Guarantee (100 days on the complete ritual). If it's not for you, contact us for a full refund — even if the bar's been used.

Your refill ships automatically every 60 days at the subscriber price. Skip, pause, reschedule or cancel anytime from your account — no fees, no lock-in.

Yes. Because there are no harsh sulfates or surfactants, Hikakai is gentler on color than conventional shampoo and helps it last longer.
