Zenagen Thickening Hair Serum The Zen Restorative Complex utilizes the natural healing power of plants to create a blend of non-toxic, natural ingredients that work to neutralize free radicals and offer a wide array of health benefits. This powerful anti-aging hair serum soothes scalp inflammation and targets hair loss at the source to grow thicker, fuller hair. When plant-based ingredients are harvested from plants, typically most of the potency is compromised during the process, and the effectiveness of the product is weakened. Adaptipure ingredients are extracted using a high-quality, cold-pressed system resulting in the ingredients being in the top 1% for potency, quality, and effectiveness. Our hair serum is formulated exclusively with 100% adaptipure ingredients and is clinically proven to help stimulate faster and denser hair growth within 3 months. This is a lightweight, residue-free serum with a smooth-watery consistency. When applied, the serum is quick to dry and will absorb into the skin without leaving behind an oily or greasy residue.
