Decibel: Thickening and Volumizing Treatment

DECIBEL™ Hypertrophy Thickening & Volumizing Treatment is a progressive intensive treatment designed to give hair more volume, body, and a visibly thicker appearance, without buildup. It is the most concentrated step in the DECIBEL™ thickening routine.

Its formula contains the 140dB™ Complex, the brand's exclusive technology. DECIBEL™ states that the ingredients used in this technology have been shown to increase hair thickness and volume by up to 74%, with effects that can last for over 20 shampoos. The formula also helps detangle, repair, and protect the hair fiber.

🧬 Key Technology – 140dB™ Complex

The 140dB™ Complex is an exclusive composition of acids and peptides developed by DECIBEL™ to act on each fiber and give it a thicker, more voluminous appearance. The brand describes its action as progressive and buildup-free, meaning that results develop with use rather than simply depositing a heavy layer on the hair.

The Thickening Treatment represents the step in the routine where the highest concentration of this technology is delivered.
