Your scalp is skin, and just like the skin on your face, it has a protective barrier and a diverse microbiome that work together to maintain hydration, comfort, and resilience. When that balance is disrupted by harsh cleansers, environmental stressors, or product buildup, the scalp can become dry, itchy, irritated, or excessively oily. 

HH Science™ Scalp Barrier + Biome formulas were developed to gently cleanse while helping support the scalp’s moisture barrier and a healthy scalp environment, leaving hair softer, stronger, and healthier-looking with every use.

Eliminate excess water. Apply a small amount of shampoo to the palm of your hand and massage into the scalp vigorously, working through the hair to the ends. Rinse thoroughly. Repeat if necessary. Follow with Barrier + Biome Conditioner for best results.
