Deep Treatment Comb — 4x the Penetration Power of Treatment, Just by Combing

After washing, up to 80% of treatment product typically stays on the comb — never reaching your hair. And wet hair, being at its most vulnerable, sustains damage every time an ordinary comb drags through it. The STRAINIA Deep Treatment Comb was engineered to solve both problems at once. Its specially coated stainless steel pins minimise friction while distributing product evenly from root to tip. Its mineral-containing resin body neutralises the electrical stress difference between the inside and outside of the hair, allowing care ingredients to penetrate four times deeper than manual application. The result: visibly smoother, more supple hair — even after blow-drying.

How the Deep Treatment Comb Works

• Even Distribution Without Friction — Specially coated SUS304 stainless steel pins allow care products to be worked through wet hair gently; friction is minimised so hair is less stressed and product is distributed optimally from roots to tips
• Mineral Stone Resin Body — The comb body is made from high-performance ABS resin containing Iio stone powder, which neutralises the electrical potential difference between the inside and outside of the hair — opening the pathway for deeper moisture absorption and sustained moisture retention
• Dual-Length Pin System — Long pins ensure even distribution of care throughout the hair; shorter pins gently loosen, smooth and add suppleness — working together to detangle and deeply condition simultaneously
• 4x Better Absorption — The combination of technologies drives treatment ingredients four times deeper than ordinary combing, maximising the results of every product in the STRAINIA ritual
• Relaxing Scalp Massage with Every Use — Each pass through the hair delivers a gentle scalp massage, promoting circulation — effortlessly and simply

How to Use

During hair care: After applying a treatment, mask or care product, gently glide the comb through hair section by section. This ensures maximum moisture absorption and an intense, well-conditioned result. Compatible with all STRAINIA products and other haircare brands.

During hair washing: Use the comb during shampooing to gently massage the scalp and promote blood circulation. A light massage before rinsing can improve the care effect and shorten washing time.

As a detangling aid: Applied to dry hair, the comb quickly and painlessly detangles knotted curls and intertwined waves without pulling or breakage.

Materials

Body: High-quality Japanese ABS resin containing Iio stone powder. Pins: 100% stainless steel, SUS304.
