The Specific Application of DHA and DHB in Hair Coloring for Blondes
Tianjin, China – August 21, 2025--Blonde hair (including platinum, sandy, dark blonde, etc.) has a very light base with minimal pigment, making it the ideal candidate for products based on DHA (1,3-dihydroxyacetone) and DHB(L-Erythrulose).
1. Desired Effects
Deepening and Adding Warm Tones: Adds warm golden brown, honey blonde, caramel, or strawberry blonde tones to overly pale or ash-blonde hair.
Creating a "Sun-Kissed" Effect: Produces natural-looking highlights and lowlights, as if the hair has been naturally lightened by the sun throughout the summer. This effect, known as "balayage" or "ombre" in French, is achieved chemically rather than through hand-painting techniques.
Evening Out Tone: Corrects uneven coloration, brassiness, or fading caused by sun exposure, swimming, or other factors.
2. Application Methods
Shampoo/Conditioner/Spray Form: Users apply the product as part of their daily hair care routine. The color builds up gradually with each use, offering high controllability and minimal room for error.
Mousse/Gel Form: Applied like a styling product to dry or damp hair, providing stronger and faster color results. Often used for creating targeted highlights.
Professional Salon Service: Stylists mix DHA and erythrulose in varying ratios, sometimes incorporating other botanical colorants, to create customized "sun-kissed" effects for clients.
3. Usage Process and Precautions
Preparation: It is recommended to cleanse hair thoroughly before application (avoid conditioners or oils) to ensure even product adherence.
Even Application: This is the most critical step. Ensure every strand is evenly coated to avoid patchy results.
Development Time: Color begins to develop within 4–8 hours and reaches its final result within 24–72 hours. Keep hair dry during this period.
Market Product Examples
Many well-known brands have launched hair color products based on DHA and L-erythrulose, which are particularly popular in the European market.
Christophe Robin: Their "Shade Variation Care" series is a salon-grade option offering multiple shades for different base colors (blonde, brunette, etc.).
Maria Nila: Known for an extensive color range and eco-friendly, gentle formulations.
Kao Lieseille: Their bubble hair color series, popular in Asian markets, also utilizes this technology to create subtle tones.
Many other professional and niche brands, such as Oway, Phyto, and John Masters Organics, offer similar product lines.
Conclusion
For individuals with blonde hair, DHA and L-erythrulose offer an extremely safe, gentle, and natural-looking hair coloring alternative. They perfectly meet the demand for ammonia-free, peroxide-free, and low-irritancy hair color products, especially suited for those seeking subtle, gradual color changes and scalp-friendly solutions.
The core technology lies in the synergistic effect of these two sugar molecules: DHA provides speed and intensity, while L-erythrulose ensures natural tones and longevity. Together, they create the highly sought-after, sun-kissed effect that mimics the natural lightening of hair under the sun.
