A Sneak Peek of Zenagen

Jared Reynolds is the man behind the success of the Zenagen hair loss treatment shampoo. During his medical studies, he began to notice his hair thinning and falling out. Armed with the knowledge he gained from his studies, he started looking for solutions to overcome his hair loss.

He found that a combination of the best nutraceuticals and an effective delivery system is the key to a natural and effective solution for hair loss.

In 2008, Zenagen was founded with the mission of making full use of plant-based ingredients to create safe and effective hair care products. Zenagan has also won the Top Award For Best Emerging Brand of Products at the 2012 HBA Global Expo for Health and Beauty.

This cruelty-free, vegan formula comes from years of proven-research to tackle the root causes of hair loss for all hair types and textures. Zenagen hair care products are divided into two lines, Revolve and Evolve. To learn more about them, let’s move on to the next section.

Zenagen Revolve and Evolve Lineup

Revolve and Evolve are the two main systems of Zenagen products, each designed to address your specific hair problems.

In short;

  • Revolve is aimed more at treating hair loss and
  • Evolve is designed to reverse the effects of hair damage.

Zenagen also offers a range of styling products, which includes the Strengthening Leave-in Conditioner, Thickening Volume Foam, Light-as-air Leave-in Cream, Thickening Texturizing Powder, and Flexture Paste, as well as hair accessories.

This review will prioritize Revolve and Evolve which consist of shampoo and conditioner. Let’s start with the Revolve line.

Revolve Hair Loss Treatment

Zenagen Revolve is highly recommended for you, if you are trying to stop hair thinning and/ or loss. This system is also suitable for those who want to take preventive measures against hair shedding, and those with thin hair who are looking for a way to thicken and add more density. Its sulfate-free shampoo is great for all hair types, including colored hair, and does not contain parabens, gluten, and alcohol.

Zenagen Revolve Hair Loss Treatment is suitable for those who experience hair loss due to:

  • Alopecia areata, caused by an autoimmune reaction in which the body attacks the hair follicles.
  • Androgenetic alopecia, caused by a combination of genetics and hormones. Otherwise known as male/ female pattern baldness.
  • Telogen effluvium, e.g. Hair loss caused by Covid-19, stress, hormone changes, postpartum, post-chemotherapy, and certain medications.
Zenage Revolve Thickening Shampoo for Men

The main ingredients of the Revolve system are Saw Palmetto, Red Clover, Brahmi, and Aloe Leaf Juice. This formula will help reduce hair shedding in 2-6 weeks, and in 3+ months your hair will appear fuller and thicker. But it’s important to remember that everyone’s results will vary, depending on the type of hair and the type of hair loss you have.

Zenagen Revolve Thickening Shampoo for Women

Use Revolve every other day or 2-3 times a week, and let it sit for 5 minutes before rinsing so the formula penetrates your scalp. Follow with Revolve Hair Loss Conditioner (Unisex) by focusing on the scalp and ends to condition and soothe scalp inflammation and irritation. It also enhances manageability and allows hair to shine without weighing it down.

Evolve Repair Treatment

Evolve is a two-step repair system (shampoo and conditioner) made from natural ingredients to promote hair growth 40% faster. This system can be used by all hair types, including those who might NOT be experience hair loss. Just like its counterpart, Evolve is also free of parabens, SLS, and gluten.

Who is it for?

  • Those who live in densely populated areas experiencing hair damage due to air pollution.
  • Anyone with dry, brittle, or damaged hair from bleaching, hair dye, or heat tools.
  • People who live in regions with humid climates that can cause unknown heat damage.

Evolve is designed to repair hair damage and create an optimal scalp environment for your hair to grow faster and healthier. This system also can retain your hair’s natural moisture, keeping it hydrated and shiny even after the first shampoo. The Evolve formula consists of a blend of Ginger Root, Lavender, Alpine Willowherb, and Grape Seed Extract, which work to stimulate stem cells, leading to faster hair growth.

Use this system 3-4 times a week by leaving the shampoo on your scalp for 5 minutes. Then follow with Evolve Repair Treatment Conditioner to restore strength and resilience of your damaged hair. With regular use, you will see longer and healthier hair after 4-8+ weeks.

In short, these two systems have different formulas and benefits from each other. It’s better to take one that suits your current hair condition. Even though both of them help hair growth, if you experience hair loss, use Revolve instead of Evolve which is more focused on repairing damaged hair.

Let’s take a closer look at their active ingredients in the next section.

Things to Consider Before Buying Zenagen Shampoo

After you learn about Zenagen’s features and key ingredients, you need to know some things to consider before investing in their shampoo. Taking the right product will maximize the benefits for your hair since their shampoos have different formulas and purposes.

Should I Take Revolve or Evolve?

Revolve and Evolve are made with different formulas because their benefits are also different.

On Revolve

The Revolve formula uses nutraceuticals and anti-aging ingredients that target DHT, the hormone that causes 95% of hair loss. Thus, Revolve is more suitable for those who experience hair loss and thinning hair. To reduce and stop hair loss, take Revolve for maximum results.

On Evolve

Meanwhile, Evolve is a hair repair and growth system. The formula is crafted to repair and even prevent damage to your hair, so it’s suitable for you with damaged or chemically-treated hair. It also helps to accelerate your hair growth 40% faster, making it longer and thicker.

If you are not experiencing hair loss and want to speed up hair growth, take Evolve instead of Revolve although it can also promote hair growth.

I am a Woman But Can I Take Revolve Shampoo For Men?

Yes, there is nothing wrong with using the opposite gender’s shampoo.

However, there is a reason why this shampoo is designed based on gender. Women’s Revolve is created with a higher concentration of anti-inflammatory ingredients than Men’s. One of the enhanced ingredients is Red Clover, which is widely used to reduce hair loss due to menopause. Women with menopause not only lack estrogen, but DHT production also increases.

Red Clover works by targeting scalp inflammation and blocking DHT, this is why the concentration is increased in Women’s Revolve. When the formula was tested on men, it did not work as effectively with lower concentrations of ingredients. Thus, it is better to take shampoo from the right line to maximize work and get the benefits that suit your hair needs.

Benefits of Zenagen Shampoo

We discuss how Zenagen shampoo works to improve your hair loss by blocking DHT as well as the real-life experiences of users. By using its nutraceutical ingredients, Zenagen is likely safe for everyone, including pregnant or breastfeeding women. Zenagen shampoo works from the hair follicles down to the ends of the hair, so it’s not only great for reducing hair loss, but also for your overall hair health. Let’s take a look at the science behind Zenagen shampoo.

Zenagen Revolve System Blocks DHT

The reason why Revolve works so well against hair loss is that the nutraceutical ingredients in it penetrate deep down into your hair follicles, not just in the top layer of the epidermis. Revolve directly targets DHT or dihydrotestosterone, the natural hormone in your hair follicles that are the main cause of 95% hair loss in many people.

After being converted from testosterone by the help of 5-alpha reductase (5-AR), DHT then travels through the bloodstream and connects to receptors in the hair follicles on your scalp. This is why DHT can cause hair loss and stunted hair growth because it shrinks hair follicles so they are unable to sustain healthy hair. Since there are no agents to help remove it, over time, DHT will multiply and accumulate, causing hair loss in both men and women.

This is exactly where Revolve comes into play. Its exclusive nutraceutical ingredients penetrate deep into your hair follicles with a green tea delivery system that stimulates your scalp. Thus, the formula helps remove DHT from your hair follicles thereby providing a healthy environment for your hair to grow. Moreover, Revolve’s plant-based nutraceutical ingredients also prevent and block DHT production forever, making it effective against hair loss as well as restoring hair fullness and shine.

How Zenagen Evolve Works in the Hair Growth Cycle

The main function of Evolve is to repair hair damage and optimize the scalp environment to promote longer and stronger hair growth. The use of nutraceutical ingredients stimulates the efficiency of stem cells to grow your hair faster. Evolve also works in your hair growth cycle by extending the anagen (growth) stage and accelerating the telogen (shedding) stage i.e. Stage 1 (growth) and Stage 3 (shedding) below.

Thus, your hair follicles will stay in the growth stage longer and stay that way for a long period.

Besides the plant-based ingredients, Evolve also contains important amino acids: PCAs, Alanine, and Histidine, which can repair, moisturize and protect the hair cuticle. As your hair’s texture is improved by PCAs, Alanine works to lock in moisture in your hair so it gets the natural shine it needs. Histidine acts as a hair protector from external factors, such as pollution, helping to keep hair cuticles tightly closed.

Again, this process takes time and it may be different for everyone. So you should be patient to see visible results after regular use of the Revolve or Evolve system. Now let’s take a look at the real-life buyer experiences below.

Possible Side Effects of Zenagen Shampoo

Even though it is made from plant-based nutraceuticals, that does not mean that Zenagen is free from side effects. Some people may experience allergic reactions or other side effects. Following are the possible side effects of Zenagen Shampoo.

  • Zenagen Shampoo contains fragrance. It may be liked by some people but those with sensitive skin might complain about the smell.
  • The product contains ammonium lauryl sulfate, which has the potential to over-dry, especially if you have very sensitive and dry skin.
  • If you’re allergic to phenoxyethanol, you may experience skin rash or in severe cases, anaphylaxis might occur. People with eczema should consult with a doctor before taking Zenagen shampoo.
  • The shampoo contains lots of derived-plant ingredients that may cause allergic reactions for some people with certain allergies to those plant-based ingredients.
  • Redness, itchy, swelling, or flaky skin/ scalp may occur due to the methylchloroisothiazolinone ingredient in the product.

By observing the ingredients and learning about your skin/ hair allergies, you will get to know that you’re not at a risk. Now, let’s check the alternatives to Zenagen Shampoo.
