- How To Use: Spray on affected area and massage into scalp. Apply 6 sprays, 2x daily, do not rinse. Wash hands with soap and water after use. Wait until dry to use styling products. For best results use in combination with Revita Shampoo and Conditioner. See growth and fuller, thicker hair within 90 days of consistent use. *Results may vary.
- Nanosome Technology: DS Laboratories formulas feature our proprietary Nanosome Technology. This technology used for encapsulation allows for the continuous release of the active ingredients creating higher efficacy with longer lasting results.

*by L***A on 26 December 2024*

Una dermatóloga me recomendó este producto y me va genial. Me he notado más volumen en la raíz ( muchísimos pelitos nuevos), no me reseca el cuero cabelludo como el Minoxidil y no me da picor. No tiene el mejor perfume (que tampoco huele mal), pero prefiero que sea eso el único fallo del producto.
