The Care Straight Brush is STRAINIA's founding innovation — engineered around the way unruly hair actually behaves. Its Y-shaped pressing structure gradually guides hair from a wide entry zone into a progressively narrower, more ordered press zone, applying controlled, even tension with every stroke. Softer bristles in the entry section ease the hair in gently; firmer bristles in the press section do the smoothing work. The result: visibly smoother, more manageable hair — no chemicals, no heat required.\u003c\/p\u003e\u003cp\u003eThe body is curved in the opposite direction to a conventional brush, following the natural shape of the head to deliver linear force evenly across each strand.

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.

It begins inside the hair fibre — in distortions of structure and uneven moisture distribution that no amount of smoothing serum can permanently fix. The STRAINIA Care Straight Treatment was developed by STRAINIA JAPAN and a professional salon research team to address the root cause: targeting the internal distortion of the hair fibre and equalising moisture from cortex to cuticle. The result, with daily use, is hair that progressively becomes straighter, smoother and easier to manage — not despite itself, but naturally.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e93% of users reported noticeable improvement in hair texture\u003c\/strong\u003e in an in-house study of 60 participants.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Fibre Correction\u003c\/strong\u003e — Targets and helps correct internal hair fibre distortion, supporting straighter, healthier-looking strands with consistent use\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrizz, Waviness \u0026amp; Uneven Texture\u003c\/strong\u003e — Reduces all three simultaneously by addressing their shared root cause — moisture imbalance and structural irregularity within the strand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeratin \u0026amp; Silk Nourishment\u003c\/strong\u003e — Hydrolyzed Keratin (Wool) and Hydrolyzed Silk AMP deeply nourish and strengthen, restoring what daily styling and environmental exposure remove\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFive-Ceramide Complex (EOP, NG, NP, AG, AP)\u003c\/strong\u003e — Replenishes the hair’s full lipid barrier, sealing in moisture and protecting against ongoing damage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat-Activated Smoothing\u003c\/strong\u003e — Meadowfoam Delta-Lactone activates with blow-dry heat to improve hair alignment and enhance the straight-hair effect\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBotanical Scalp Support\u003c\/strong\u003e — Chamomile, Roman Chamomile, Cornflower, Linden, Calendula and St. John’s Wort extracts soothe the scalp and support a healthy hair growth environment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for Resistant Frizz Patterns\u003c\/strong\u003e — Formulated to address multiple frizz types, including complex and resistant curl and wave patterns\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cp\u003eAfter shampooing with STRAINIA Care Straight Shampoo, apply an appropriate amount to mid-lengths and ends.
