This hair treatment system combines a 120ml Neo Hair Lotion with a derma roller device. The lotion is designed for hair growth and scalp treatment, while the derma roller helps improve product absorption and stimulate the scalp. The complete system aims to address hair loss and promote healthier hair growth. Since this is a personal care product, detailed usage instructions should be followed carefully. The Neo Hair Lotion should be applied directly to the scalp, while the derma roller can be used to enhance absorption. For best results, the system should be used consistently as part of a regular hair care routine. As with any personal care product, patch testing is recommended before full application.
