Okari Persimmon Shampoo

It’s not a hygiene problem, it’s chemistry. After about 40 your scalp produces 2-nonenal — an oil-based compound that ordinary shampoo slides straight over, and your hair holds on to it. You can wash every day and it still comes back. Persimmon tannin is what actually binds and removes it.

Fragranced shampoos, dry shampoos and hair mists either mask the smell or soak up surface oil — none of them touch 2-nonenal. Persimmon tannin is the one ingredient shown to bind it and rinse it away at the source.

Use it in place of your normal shampoo. Lather into wet hair and scalp, massage gently — focusing on the roots and the areas that hold buildup — leave it for 30 seconds, then rinse thoroughly. Repeat if you’ve gone a few days between washes. Follow with conditioner on the lengths if you normally do.

We use tannin from unripe kaki persimmons, picked in a short window early in the season when the tannin concentration is at its peak. It’s then slowly extracted and fermented the traditional Japanese way (a process called kakishibu). That potency is what lets it bind and wash away 2-nonenal — ripe fruit, or a cheap splash of persimmon, simply can’t.

Five core ingredients, each with one job: Persimmon tannin removes the odor at the source; green tea extract slows new odor forming between washes; hydrolyzed collagen helps mature hair stay strong and smooth; coconut oil and sodium hyaluronate hydrate the lengths and the scalp; and a sulfate-free amino-acid base clears buildup without stripping. No SLS, no parabens, no synthetic perfume — just lavender.

Most use ripe fruit or only a trace of tannin — which does about as much as regular shampoo. Okari uses concentrated tannin from unripe persimmons, where it’s strongest, so it’s actually potent enough to work.

Yes — it was formulated for mature hair first. It’s sulfate-free, so it’s safe on colour and won’t strip the scalp, and coconut oil, hydrolyzed collagen and sodium hyaluronate keep it comfortable. If you have a diagnosed scalp condition, check with your doctor as you would with any new shampoo.

No. Because it’s sulfate-free it cleanses without stripping, leaving hair soft and the scalp comfortable rather than tight and itchy. It’s designed for regular use.

Soft lavender — light and clean, not a heavy perfume. It works by removing odor at the source rather than covering it, so what’s left is a faint lavender finish that fades into just-clean hair.

Yes — plenty of customers do. It looks and lathers like an ordinary shampoo, so you can simply swap the bottle into the shower. No routine change and no awkward conversation.

Yes — and the pillow is usually where people notice it first, because your head rests on it for eight hours. That smell is 2-nonenal transferring off your scalp and hair. Remove it at the source and there’s nothing left to transfer.

Yes. On thinner hair the scalp is more exposed, which is exactly where 2-nonenal is produced — so it often works faster. The sulfate-free base rinses clean without leaving weight or residue behind.

Your nose adapts to your own scent, so the best signs are other people — someone hugging you without reacting — and your pillowcase staying fresh between washes. Most people also notice their roots stay clean a day longer than they used to.

Each bottle is 8.45 oz / 250 ml — about a month if you wash every other day, closer to three weeks if you wash daily. Most people take the 3-month supply so they’re not reordering constantly.
