Kao’s ‘melt’ Unleashes Deep Series: The Secret to Silky-Smooth, Radiant Hair
Kao Corporation is expanding its high-premium haircare brand, “melt,” with the launch of its new “Deep Series,” specifically formulated to address hair with accumulated damage from repeated coloring and heat styling. This innovative series, featuring a “Nano-penetration care formula” designed to deeply replenish and repair compromised hair, will be available nationwide on March 14, 2026, with an early release starting February 7, 2026, through Kao’s official online channels.
The “melt” brand, introduced in spring 2024 with the core concept of “Resting Beauty”—transforming haircare into a cherished personal time—has already garnered significant acclaim. Its “Moist Series” for dry and frizzy hair, launched in April 2024, and the “Smooth Series” for wavy hair, released in March 2025, have achieved a combined shipment exceeding 7 million units. This success highlights a growing consumer desire for self-care rituals that extend beyond mere functionality.
Recent research indicates that many individuals, especially those with an active interest in beauty and self-care, face increasing hair damage. This damage stems not only from chemical treatments and heat styling but also from daily stressors like dryness, friction, tangles, and humidity. Recognizing this widespread concern, the “melt” Deep Series aims to provide intensive repair, transforming damaged hair into what the brand describes as “toro-tsuya” hair—luxuriously smooth and radiant from root to tip.
Unveiling the Deep Series Lineup
The “Deep Series” lineup consists of three key products, each meticulously crafted to deliver a concentrated repair experience:
-
Melt Deep Shampoo & Deep Treatment: These products incorporate the highest concentration of “Deep Repair Ingredients” within the “melt” series. The shampoo utilizes an amino acid-based cleansing component to gently yet effectively cleanse, while both the shampoo and treatment work to smooth the hair surface, protect against friction, and target internal damage cavities. The “Nano-penetration care formula” ensures that active ingredients reach deep into the hair’s protein layers, intensively repairing voids and promoting supple texture and beautiful shine.
-
Melt Deep Conditioning Water: This leave-in treatment features a “Deep Serum formula” that envelops each strand with a melting sensation. It penetrates deep into hair damaged by accumulated stressors, providing internal repair. Notably, this marks the first time “melt” conditioning water incorporates hair internal repair technology, working to soften hair that has become stiff from damage, making it more manageable and imparting a glossy finish.
All products in the “Deep Series” share a captivating “Mindful Aroma Water Lily & Wood” fragrance. This scent, which includes a blend of high-quality natural essential oils, combines fresh aromatic green notes with warm woody accents, creating an aroma that encourages deep relaxation—a perfect embodiment of the “Resting Beauty” philosophy. Consumers seeking a moment of mindful indulgence in their daily routine will find a haven in the ‘melt’ Deep Series, transforming hair care into a truly restorative experience.
Availability and Further Exploration
The “melt” Deep Series will be available nationwide from March 14, 2026. For those eager to experience the collection sooner, an exclusive先行発売 (pre-sale) will begin on February 7, 2026, via Kao’s official online shops, My Kao Mall, Rakuten, and Qoo10.
