21 to Grow: Formulated with success in mind

At Replenology, we understand the emotional toll that hair loss can cause for both men and women at any age. It can affect our life at home, at work, and in every way we interact with friends and family.

We also understand the frustration you feel when products promise to solve the problem but end up letting you down. Did you know that the leading drug on the market focuses on only one root cause of hair loss, has a 75% rate of failure and the potential for unwanted drug side effects?

Replenology is the only certified environmentally responsible, natural and vegan nutrient replenishment system for thinning hair, scientifically formulated to address more than 21 known causes of hair loss.

Replenology restores the missing essential nutrients that deplete with age, which you need for hair growth. Our system truly goes to the source of your hair loss and gives you the best opportunity to overcome the challenge of your thinning hair.


Created in-lab by scientists with decades of experience in molecular biology
and cell stimulation, our four components work together day and night to
synergistically create the perfect environment for full, lustrous hair.


A Hair Loss Solution That Benefits Your Whole Body

At Replenology, our scientists are dedicated to specifically identifying natural, plant based nutrients scientifically shown to be essential for hair growth, but are not found in a normal daily diet or in other hair loss products.

We are fully committed to providing a solution to hair thinning and loss that is beneficial to your whole body. You can rest assured that we fully understand how devastating hair loss can be. Our devotion to overcoming your difficult challenge with a healthy and environmentally responsible solution ensures that you can now have the best opportunity for success.
