Glycerin is naturally formed during the cold-process soap-making method. Glycerin is a natural humectant (softener and moisturizer) which helps draw and retain moisture into the skin and scalp. It is believed to penetrate hair and skin, softening and swelling it, making it water retentive.
Daily Hair Tip
Gently scrubbing your scalp w/your fingertips or fingernails when showering is a fab way to give dandruff the brush off. When combined w/ a good dandruff treatment shampoo, light finger scrubbing removes dead skin cells from the scalp.
