The STRAINIA Care Straight Oil goes further. Developed by leading Japanese hairdressers specifically for very dry, frizzy and damaged hair, its formula is built around pure Japanese liquid silk and highly concentrated keratin — two actives whose molecular structure closely mirrors that of human hair, allowing them to penetrate the shaft rather than simply coat it.\u003c\/p\u003e\u003cp\u003eThe result is genuine structural repair: the cuticle is smoothed, hair breakage is reduced, and the hair emerges supple, shiny and noticeably more resilient. Four premium vegetable oils — rice bran, jojoba, camellia and safflower — work alongside to deliver deep moisture, restore the hair’s natural protective barrier and keep it elastic and strong against external stressors.\u003c\/p\u003e\u003cp\u003eTwo heat-active lactone ingredients complete the formula. On contact with blow-dryer or straightener heat, they bond with the hair to seal in moisture, protect the cuticle from heat damage and deliver long-lasting smoothness — while also significantly reducing blow-dry and straightening time.\u003c\/p\u003e\u003ch4\u003eKey Ingredients\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsostearoyl Hydrolysed Silk\u003c\/strong\u003e — Pure Japanese liquid silk; penetrates the hair shaft to smooth the cuticle and reduce breakage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsostearoyl Hydrolysed Keratin (Wool)\u003c\/strong\u003e — Highly concentrated keratin that strengthens the hair structure from the inside out\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRice Bran Oil (Oryza Sativa Bran Oil)\u003c\/strong\u003e — Rich in vitamins and fatty acids; deeply nourishes and adds shine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJojoba Oil (Simmondsia Chinensis Seed Oil)\u003c\/strong\u003e — Mimics the hair’s natural sebum; balances moisture without heaviness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCamellia Oil (Camellia Japonica Seed Oil)\u003c\/strong\u003e — Traditional Japanese hair oil; penetrates deeply for softness and lustre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafflower Oil (Carthamus Tinctorius Seed Oil)\u003c\/strong\u003e — Lightweight oil that restores the hair’s natural protective barrier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eγ-Docosalactone \u0026amp; Meadowfoam Delta-Lactone\u003c\/strong\u003e — Heat-activated actives that bond with hair under heat to seal moisture and provide lasting smoothness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eHow to Use\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eOn damp hair (recommended):\u003c\/strong\u003e After shampooing, apply to towel-dried hair.

The Care Straight Oil embodies this: instead of masking frizz with a surface coating, it works from within, using ingredients that mirror the hair’s own building blocks to restore it to its most beautiful natural state.\u003c\/p\u003e\u003ch4\u003eFull Ingredients\u003c\/h4\u003e\u003cp\u003eIsododecane, Triethylhexanoin, Rice Bran Oil, Simmondsia Chinensis Seed Oil, Camellia Japonica Seed Oil, Carthamus Tinctorius Seed Oil, Isostearoyl Hydrolyzed Silk, Isostearoyl Hydrolyzed Keratin (Wool), Isostearic Acid, Isononyl Isononanoate, γ-Docosalactone, Meadowfoam Delta-Lactone, Caprylic\/Capric Triglyceride, Tocopherol, Fragrance\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents:\u003c\/strong\u003e 60ml\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e Japan\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Onsen Hair Spa","offers":[{"title":"Default Title","offer_id":59164374237529,"sku":null,"price":39.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1033\/2690\/8761\/files\/18_1ea094aa-1c7f-4572-9153-f174c4e98184_png.webp?v=1787750071","url":"https:\/\/onsenhairspa.com\/products\/strainia-care-straight-oil","provider":"Onsen Hair Spa","version":"1.0","type":"link"}
