Hair loss is and will remain a daily concern in many people’s lives, but fortunately, Redensyl is here to help. People are spending colossal amounts of money in an attempt to make their hair grow faster, which in most cases turns out to be in vain. While the hair recovery market was valued to reach $934 million by 2023, the American Hair Loss Association claims that 99% of all products marketed are completely ineffective. This has driven experts around the world to find alternatives to combat hair loss, hence Redensyl.

Everyone’s seeking products with active ingredients to boost their hair. Women especially seem more interested in hair care products than in drugs and laser treatments, mainly because the tolerance rate is higher. Since hair products are classified as cosmetics, they do not need FDA approval before entering the market, which means their effectiveness cannot be proven. Yes, that’s right. There is no way to prove that a product is effective or not but to check the active ingredients in its formulation. If the product includes ingredients proven to promote hair growth, it may worth a shot. If not, you’d better avoid it. 

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


What is Redensyl?

Redensyl is a breakthrough ingredient clinically tested to encourage hair growth in men and women and is mostly found in serums because they absorb better in the scalp. Redensyl was developed from Induchem Laboratories (Switzerland and USA). Induchem’s center came up with Redensyl after analyzing the hair follicles’ stem cells (HFSCs) role in the hair growth cycle. They confirmed that HFSCs have a crucial function in initiating the hair’s growth phase, thus the need for an activator of hair follicle stem cells became a primary concern for them.

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. You must probably have never heard about DHQG and EGCG2, and they may seem very confusing at first, but they actually have specific roles in stimulating hair follicles and maintaining hair thickness. If you want 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.

Hair loss & Redensyl

hair follicles structure

The hair follicle is surrounded by two main structures – the inner root sheath (IRS) and the outer root sheath (ORS). While IRS helps shape and mold the newly developing hair shaft, ORS includes a region known as the bulge, which contains epithelial stem cells responsible for regenerating follicles in the growing stage. Practically, 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. Similarly, hair follicle dermal papilla cells (HFDPc) form an instructive niche for the stem cells to form new hair.

In order to grow hair, the hair follicle undergoes cycles of degeneration and regeneration due to stem cell involvement. 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 migrate along with the ORS to the follicle base, where they produce new hair shafts.

How Redensyl work for hair loss?

After years of research, the conclusion was reached: stem cells play a major role in stimulating hair follicles to produce new hair. Knowing this, Induchem’s laboratories have developed Redensyl with the role of reactivating hair follicles stem cells (HFSCs) and dermal papilla fibroblasts. If HFSCs activity increases, the telogen phase’s duration will decrease, followed by an increased ratio density of hairs in the anagen phase. It will practically shorten the resting phase while more hair will be moved in the growing phase, ending up with a fast and sustainable production of new healthy hair. One study, led by T. Matsuzaki and K. Yoshizato, validated that “dermal papilla cells and dermal sheath cells have the ability to induce and form hair bulbs under preferred environmental conditions.”

Redensyl formulation explained

DHQG, used in the formulation of Redensyl, can stimulate the stem cells cellular activities in the ORS and dermal papilla, the two primary cells involved in new hair formation. In their study, Induchem’s laboratory claims that the metabolism in derma papilla stem cells was improved from 12% to 24%, while the propitiation of ORS steam cells has improved from 28% to 44%. Also, because an irritating scalp is more prone to be losing hair, they’ve used EGCG2 due to its anti-inflammatory properties. One research in 2007 reported that EGCG might help prevent or treat androgenetic alopecia by promoting hair growth in follicles and dermal papilla cells’ proliferation. The other two compounds, glycine, and zinc are added to reinforce the hair shaft structure. 


Does Redensyl really promote hair growth?

Yes, Redensyl is actually among the fewest ingredients that make sense to use for hair growth and thickness. Induchem Laboratories demonstrated via clinical investigations that Redensyl effectively treats androgenic alopecia and more generally treats various hair loss conditions in men and women. They concluded that Redensyl works in 3 months by promoting hair follicles’ conversion into the growing phase, with up to 28,000 new hairs observed by the end of this period. As per their report, more than 71% of people involved in their investigations were declared satisfied with their hair loss conditions after treated with Redensyl.

Redensyl clinical studies for hair loss

Induchem Laboratories found out that, after 7 to 10 days, the hair follicles treated with 1% Redensyl produce faster and healthier hair than untreated follicles or treated with Minoxidil. Studies show +214% more hair in patients treated with Redensyl, compared to +118% for the Minoxidil group. In another study, they’ve treated 13 men suffering from hair loss with Redensyl, while the other 13 have been given a placebo hair lotion. After 3 months of treatment, Redensyl increased the percentage of hairs in the anagen phase by +9% and decreased the telogen phase’s hairs rate by about 17%. Among the Redensyl group, 12 out of 13 people were responders to the treatment and reported denser, thicker, and fuller hair.

How to use Redensyl?

Redensyl is found as an active ingredient in the formulation of hair serums and oils. Get yourself a Redensyl product and apply it as follows. First, rinse your hair thoroughly with warm water. Then place dropper on the scalp target areas and move through, squeezing gently to disperse small drops, not full droppers. Massage into scalp to ensure even distribution and then rinse off foam from hair with warm water. Do this for three months and notice if your hair loss condition is improved. 

Does Redensyl have side effects?

Because Redensyl is plant-based and bio-processed is believed to have little to no side effects at all. Most studies conducted on Redensyl haven’t reported any harmful side effects, suggesting Redensyl is a safe and risk-free ingredient for hair.

Final words

Let’s get it straight: hair loss is treatable in very few cases, especially with serums. It will take a long time to see results no matter what treatment you use. Even with Minoxidil or Redensyl, you have to apply the treatment for longer periods continually – at least three months. Compared with other hair care ingredients, Redensyl does not lack evidence and is actually clinically tested to promote hair growth.

Quick questions

  1. Does Redensyl thicken hair?

    Yes, besides reducing hair loss and encouraging new hair growth, Redensyl also thickens the existing hair, making it appear denser, voluminous, and healthier when used regularly.

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

    Depending on your hair loss severity, 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.

  3. 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. At this very moment, the only treatments for hair loss approved by the FDA are minoxidil and finasteride.

  4. Can you mix Redensyl with other ingredients for better results?

    Yes, you can use Redensyl in conjunction 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 two breakthrough formulas for hair growth.

  5. Is Redensyl a DHT blocker?

    No, Redensyl does not have any mechanism to stop DHT conversion. If elevated levels of DHT cause your hair loss condition, it's best to use a DHT blocker such as saw palmetto together with Redensyl. 

  6. Which is best Redensyl or minoxidil?

    As they have different mechanisms to stop hair loss, it's difficult to compare them. Minoxidil is a vasodilator used to expand blood vessels and boost blood flow to the scalp in order to stimulate hair growth. Both minoxidil and Redensyl are research-backed treatments, and their effects on hair were demonstrated in clinical studies. However, compared to Redensyl, minoxidil is an FDA-approved treatment and has been subjected to more trials. Besides, no studies directly compared Redensyl with minoxidil, but rather in a combination of Redensyl, Capixyl, and Procapil, which was found to work better than minoxidil alone.
