Diamax Advanced Hair Thickening Serum from Nioxin is an innovative serum formulated to provide the appearance of thicker, denser hair from the first application. With advanced technology, this treatment penetrates deeply into the hair fiber, increasing the diameter of each strand for an immediate effect of volume and fullness.
Thanks to its formula enriched with strengthening ingredients, Diamax Advanced significantly reduces hair breakage, helping to preserve hair length and resistance. Furthermore, it acts on the scalp, providing hydration and protection against external factors that could weaken the hair.
This serum is ideal for those who have fine hair or those with signs of thinning and want to improve its density without compromising the lightness or natural movement of the strands. With continued use, hair becomes visibly stronger, healthier and more resistant, giving it a more voluminous and vital appearance.

Active ingredients:
HTX Technology – Increases strand diameter for thicker hair.
Caffeine – Stimulates microcirculation in the scalp for healthy growth.
Niacinamide – Strengthens and protects the hair structure.
Panthenol – Moisturizes and improves hair elasticity.

Hair texture and type:
Lightweight, quickly absorbed serum, leaving no residue.
Recommended for fine hair or hair with signs of thinning.

People with thin or weakened hair looking for more volume.
