Using the entire bundle enhances the potential for hair growth due to the combined effects of the derma stamp, scalp massager, and the Mane Elixir Blend. The derma stamp and scalp massager individually stimulate the scalp, potentially boosting blood flow and making it a more receptive environment for the nutrients and active ingredients in the Mane Elixir Blend. This combination of mechanical stimulation and nutrient delivery can lead to more effective results compared to using the products individually.
