Questions, answered

Find the right routine with confidence

Clear guidance on choosing, using, and evaluating My Hair Science formulas.

Which My Hair Science product is right for me?

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.

What is the difference between Kenogen Men and Kenogen Women?

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.

How long should I use a hair-care routine before evaluating it?

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.

What does Clinical Derm add to a routine?

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.

How does Alizard differ from conventional hair dye?

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.

What if a product is not right for me?

My Hair Science offers a 30-day money-back guarantee. Email support@myhairscience.com with your order information for help. If you experience irritation or have a diagnosed scalp condition, discontinue use and consult a qualified healthcare professional.
