Unlock the full potential of your hair with the SAI Botanical Hair Growth Serum, a harmonious blend of nature’s finest botanicals and clinical innovation.
Each drop nourishes the scalp, supports healthy follicle activity, and enhances natural shine—delivering the foundation for fuller, thicker, more radiant hair.

Infused with Rosemary Extract to revitalize the scalp and Ginger Root Extract to restore balance, this serum also contains Densidyl™, a powerful fusion of Chlorella Emersonii and Spirulina Maxima that energizes follicles and promotes density.
