Three targeted systems. Three distinct hair concerns. One science-led approach.
Your hair needs aren't one-size-fits-all. Neither should your hair care be.
Developed by molecular biologist Jared Reynolds, Zenagen brings together advanced formulation science and targeted hair and scalp care to support different hair needs.
Whether you're looking for visibly fuller hair, improved strength and manageability, or longer-lasting color vibrancy, choosing the right system starts with understanding what your hair needs most.
Here's how Revolve, Evolve and Eclipse compare.
Revolve: For Thicker, Fuller-Looking Hair

Best for: Fine, thinning or low-density-looking hair, including hair experiencing changes in visible fullness.
Revolve is Zenagen's scalp-focused thickening system, designed to support the appearance of fuller, healthier-looking hair.
Unlike a traditional wash-and-rinse shampoo, Revolve features a five-minute scalp-contact protocol as an intentional part of the routine.
The routine:
Apply Revolve Shampoo to wet hair and scalp, massage thoroughly and leave on for five full minutes before rinsing. Follow with Revolve Conditioner as directed.
For additional scalp-focused support, incorporate Zenagen Densifying Hair Serum into your routine according to its usage instructions.
Why choose Revolve?
If your primary concern is visible thinning, reduced fullness or fine hair that lacks density, Revolve is the system to explore.
Evolve: For Damaged, Dry or Fragile-Feeling Hair

Best for: Hair experiencing dryness, dullness, breakage or the visible effects of heat styling and chemical processing.
When hair becomes damaged, it can feel rougher, appear duller and become more difficult to manage.
Evolve is Zenagen's strengthening and conditioning system, formulated to help improve the appearance and feel of compromised hair.
The routine:
Apply Evolve Shampoo to wet hair and scalp, following the recommended five-minute contact time. Follow with Evolve Conditioner, concentrating on the mid-lengths and ends and allowing it to remain on the hair for the recommended time before rinsing.
Why choose Evolve?
If your hair's biggest challenge is damage, dryness or fragility rather than visible thinning, Evolve is designed to help improve softness, strength and manageability.
Eclipse: For Color-Treated Hair

Best for: Color-treated hair that needs help maintaining vibrancy, shine and overall hair condition between salon visits.
Color is an investment. Your hair care should help you maintain the look you love.
Eclipse is Zenagen's dedicated color-care system, designed with the needs of color-treated hair in mind.
The routine:
Use Eclipse Shampoo and Conditioner according to the product directions, focusing on consistent cleansing and conditioning care between salon appointments.
Why choose Eclipse?
If maintaining your salon color's appearance, shine and vibrancy is your top priority, Eclipse is the system designed for you.
Revolve vs. Evolve vs. Eclipse: At a Glance
| Your Primary Hair Concern | Zenagen System |
|---|---|
| Fine or visibly thinning hair | Revolve |
| Dry, damaged or fragile-feeling hair | Evolve |
| Color-treated hair and vibrancy maintenance | Eclipse |
What If You Have More Than One Hair Concern?
Hair needs aren't always limited to one category.
You may have fine, color-treated hair. Or hair that feels damaged while also experiencing changes in fullness.
The key is to identify your primary hair concern and choose a system designed around that need.
For example, if visible thinning is your main concern, Revolve may be your starting point, even if your hair is also color-treated.
If your priority is maintaining color vibrancy, Eclipse may be a better fit.
A Zenagen salon professional can help you evaluate your hair's condition and choose a routine that fits your goals.
