With the shampoo for hair growth stimulation and the complete Long & Strong line, you can effectively and gently stimulate your hair growth. The hyper-performing formulas with Centella Asiatica, Marine Density Infusion, and biomimetic peptides nourish the scalp, strengthen the hair from the roots, and support the natural growth cycle.

Keune's Long & Strong line is energized by Centella Asiatica, Marine Density Infusion, and biomimetic peptides. Centella Asiatica improves scalp circulation, Marine Density Infusion strengthens hair and increases density, and biomimetic peptides extend the growth cycle. Together, they ensure stronger, fuller, and healthier hair.

You can stimulate hair growth with the Long & Strong products. The shampoo gently cleanses and prepares the scalp for growth. The conditioner nourishes and strengthens hair, reducing breakage. The Densifying Leave-in Treatment supports hair density and extends the growth cycle without rinsing. The hair growth serum works directly on the scalp: apply it section by section, massage it in, and leave it in for maximum stimulation.
