Summary

Permanent hair dyes are commonly used in over the counter direct to consumer products and within hair salons. Allergy, also known as contact dermatitis, to hair dye is a well known phenomenon. Herein, we seek to decrease the risks of allergy to hair dyes by testing a novel version of p-phenylenediamine (PPD) with less allergy potential.

Conditions

  • Contact Dermatitis
  • Allergy; Dermatitis
  • Dermatitis
