Questions, answered
Clear guidance on choosing, using, and evaluating My Hair Science formulas.
Choose Kenogen Men or Kenogen Women for a scalp-conscious routine for thinning-looking or weakened hair. Choose Alizard Brown or Black for gradual gray blending, based on your natural starting shade. Choose Clinical Derm when focused scalp cleansing is the priority. Each product page includes more detailed guidance.
Both are melatonin-based hair and scalp formulas from Vivipharma, but each is designed around the needs and routine preferences of its intended user. Select the formula that matches you and follow the directions shown on its product page and packaging.
Hair and scalp routines require consistency. For Kenogen, Vivipharma describes a 12-week efficacy period. Cosmetic results vary by person, so follow the product directions and evaluate changes over time rather than after only a few washes.
Clinical Derm is positioned as focused scalp cleansing and care. It can be a useful option when your main goal is maintaining a clean, comfortable scalp environment. Review the Clinical Derm product page for complete directions.
Alizard is a cosmetic, two-part gray-blending routine designed to create a gradual change over repeated applications. Choose Brown for brown starting shades and Black for black or very dark starting shades. It is not presented as a permanent one-step color treatment.
