Active Ingredients:
Hyaluronic Acid: retains moisture in the hair, giving it elasticity and softness. Silicone Polymers: smooth the surface of the hair, reducing frizz and making it easier to comb. Ceramides: strengthen the hair fiber, preventing breakage and split ends.

Target Audience:
The Fundamental Filler Serum is ideal for those looking for a versatile and effective product to moisturize, soften, and protect the hair against damage caused by heat and pollution. It is suitable for daily use as part of a hair care routine.
