SNCA Products SGA-7 is a semi-noncorrosive acid wash with an enzyme specifically for human scalp regeneration. The scalp hair follicles are covered by natural oils that inhibit hair growth. SGA-7 simply dissolves the heavy oils and in combination with our enzyme growth stimulator, hair now has a chance to grow. We are completing several years of intense trials and the results are amazing. Our shampoo and conditioner will aid in the most natural approach for healthy and manageable hair. Our hair relaxer product line also addresses extremely curly hair and will straighten without the need for heat, significantly improving hair health without the use of toxic alternatives.
