Today, we will talk about one of the most effective hair growth stimulators found in cosmetics: Redensyl. Here is everything you need to know about this potent ingredient.

What is Redensyl?

Redensyl is an innovative ingredient that stimulates hair growth and enhances hair thickness and density. It is the result of extensive research by Induchem Laboratories (Switzerland and USA) on the role of hair follicle stem cells (HFSCs) in the hair growth cycle. They discovered that HFSCs are essential for initiating the growth phase of the hair, and therefore they developed Redensyl as an activator of these stem cells.

What is Redensyl made of?

Redensyl is obtained from a combination of botanical ingredients and contains 0.005% dihydroquercetin-glucoside (DHQG), 0.0009% epigallocatechin gallate-glucoside (EGCG2), 0.005% glycine, 0.002% zinc chloride, 0.015% metabisulfite, and 50% glycerin. To understand how Redensyl works, you first need to understand the hair follicle structure and how it produces hair. We will try to explain this in very simple terms.

Understanding the hair growth process

The hair follicle is surrounded by two main structures: the inner root sheath (IRS) and the outer root sheath (ORS). While IRS forms the hair shaft, ORS includes a region known as the bulge, which contains stem cells responsible for regenerating follicles in the growing stage. In simple words, these ORS stem cells (ORSc) have the potential to form new hairs.

Another essential structure is the dermal papilla, situated at the very bottom of the hair follicle. Dermal papilla contains blood vessels with the role of delivering nutrients to each follicle and hair shaft.

In order to grow hair, the hair follicle undergoes cycles of degeneration and regeneration. These phases are called anagen, catagen, and telogen. At the beginning of each new anagen phase, the follicles start a regenerating process that requires a reservoir of follicle stem cells. While in the anagen phase, the hair is actually growing until it enters the catagen phase, marked by the end of the reproduction of ORS stem cells. In the telogen phase, most ORSc are in a dormant state, and the hair follicles remain inactive for about 3 months before the whole cycle repeats. Once follicle stem cells become activated, they produce new hair shafts.

How Redensyl stimulated hair growth

Induchem’s laboratories have discovered that stem cells are the key to stimulating hair follicles to produce new hair. Based on this finding, they have created Redensyl, a product that activates hair follicle stem cells (HFSCs). Redensyl reduces the resting phase of the hair cycle and increases the number of hairs in the growing phase. This leads to healthy hair growth by shortening the telogen phase and boosting the anagen phase.

Redensyl formulation explained

Redensyl contains DHQG, a compound that activates the two main cells responsible for new hair growth. According to research, DHQG increased the cellular metabolism of dermal papilla stem cells from 12% to 24%, and the activity of ORS stem cells from 28% to 44%. Redensyl also has EGCG2, a compound that reduces inflammation, which can affect hair quality. The other two compounds, glycine and zinc reinforce the hair shaft structure. 

How to use Redensyl?

You can find Redensyl as an active ingredient in some hair serums and oils. Get yourself a Redensyl product and apply it as follows:

First, wash your hair well with warm water. Then apply small amounts of the product on the areas of your scalp that need it. Gently massage your scalp to spread the product evenly and then rinse off with warm water. Do this for three months and see if your hair condition improves.

Is it safe?

Redensyl is bio-processed, so it has little to no side effects at all. Most studies suggest that Redensyl is a safe ingredient for hair growth.

Frequently asked questions

  1. Does Redensyl thicken hair?

    Yes, Redensyl thickens the existing hair, making it appear denser and voluminous

  2. Which is best, Redensyl or minoxidil?

    Minoxidil and Redensyl are both treatments that can help you grow more hair, but they work differently. Minoxidil is a medicine that widens the blood vessels and increases the blood flow to your follicles, which stimulates the hair follicles. Redensyl is a natural ingredient that activates the stem cells in your hair roots, which boosts the hair growth cycle. Both of these treatments have scientific evidence to support their effectiveness, but minoxidil has an advantage. Minoxidil is approved by the FDA and has been tested in more studies than Redensyl.

  3. How long does it take for Redensyl to work?

    Depending on your condition, it may take between 2 to 6 months to notice changes. Most studies performed on Redensyl reported visible improvements in hair count, density, and thickness after 3 months of daily use.

  4. Is Redensyl approved by the FDA?

    No, Redensyl is not FDA-approved. However, Redensyl does not lack scientific evidence, and its effects on hair have been proven in clinical trials multiple times.

  5. Can you mix Redensyl with other ingredients?

    Yes, you can use Redensyl with other treatments or ingredients to boost the results, including minoxidil. In fact, minoxidil can act as a booster for Redensyl and, when used together, may encourage faster hair growth. Besides, Redensyl works great with Capixyl and Procapil, the other hair growth stimulators.

  6. Is Redensyl a DHT blocker?

    Redensyl does not block DHT conversion. If you suffer from androgenic alopecia, it’s best to use a DHT blocker such as saw palmetto together with Redensyl.
