Founders of S.T.R.A.N.D.™

Dr. Kindred and Susan L. Peterkin also co-founded S.T.R.A.N.D.™, a stylist education organization that bridges the gap between hairstylists and dermatologists to address hair loss and scalp concerns.

Deep Moisturizing line uniquely formulated with two standout active ingredients:

  1. Panthenol (Pro-Vitamin B5)

    The moisture

    A humectant that draws in moisture and holds it, leaving hair smooth, soft, and hydrated wash after wash.

  2. Moringa Seed Oil

    The nourishment

    Pressed from the seeds of the moringa tree, this lightweight, antioxidant-rich oil has been prized for centuries. It conditions dry strands and adds softness and shine without weighing hair down.
