Nioxin Diamax Advanced Hair Thickening Serum is a powerful leave-in treatment formulated to boost the thickness and fullness of each hair strand. Ideal for those experiencing thinning hair, this lightweight serum helps reinforce hair resilience, making it more resistant to breakage and styling stress. It penetrates deep into the hair to support strength from within, leaving hair looking visibly fuller, more voluminous, and healthier over time, without weighing it down or leaving residue. Suitable for daily use on fine or thinning hair, and gentle enough for color-treated or chemically processed hair, while still delivering noticeable thickening results.
