Chlorine sticks to your skin/hair and keeps drying it out long after you leave the pool. Sonochi uses peach leaf extract, a plant-based ingredient known to help reduce chlorine-related damage. We then boost hydration with real honey — a natural humectant that pulls moisture into the skin/hair and helps lock it in. This keeps skin/hair soft and smooth, instead of dry and irritable after swimming.

We focus on clean, thoughtfully chosen ingredients that actually work. Sonochi uses plant extracts like peach leaf and yuzu, real honey for hydration, gentle amino acid-based cleansers, and moisture-boosting ingredients like hyaluronic acid. We avoid harsh chemicals and unnecessary fillers — because as swimmers ourselves, we know fighting pool chemicals with more chemicals just doesn’t make sense.

Yes — and it does it at the source. By removing chlorine buildup instead of just covering it up, Sonochi helps eliminate that lingering pool odor. Then it leaves behind a warm, fresh honey scent that lasts, so you smell clean and refreshed instead of like chlorine or the locker room.

Honey is one of nature’s best moisturizers. It’s a natural humectant, meaning it draws moisture into hair and skin and helps lock it in. After swimming, chlorine strips away hydration — honey helps bring it back, leaving hair softer, smoother, and shinier, and skin feeling comfortable and refreshed. It also gives Sonochi that warm, fresh scent swimmers love.

Yes — Sonochi was created for daily swimmers. Our gentle formulas use mild cleansers and hydrating ingredients so you can wash once or even twice a day without drying out your hair or skin. It’s made to keep things balanced, hydrated, and healthy no matter how often you swim.

Sonochi was created by college swimmers who experienced chlorine damage firsthand and couldn’t find products that truly worked for daily pool life. We partnered with experienced manufacturers in Japan to develop high-quality, carefully formulated products using proven ingredients. Every formula is built around performance, clean ingredients, and real swimmer needs — not trends. We made Sonochi because we wanted something better for ourselves, and now we’re sharing it with you.

Most swimmers notice a difference right away — hair feels softer, smoother, and less dry after the first wash, and skin feels more comfortable instead of tight. With regular use, hydration improves, chlorine smell stays away, and hair becomes stronger and shinier over time as moisture and repair ingredients do their job.

If you swim daily, the Post Practice Trio (shampoo, conditioner, and body wash) is the best choice. It gives you full chlorine care from head to toe — removing buildup, restoring moisture, and keeping both hair and skin healthy after every swim.
